[Dovecot] Configuring for virtual users
by Gerard Seibert 10 Dec '06

10 Dec '06

I haven't tried this yet; however, I would like to know if it would work. Using Postfix, I am setting up numerous virtual users. These users obviously do not have an account on the mail server. I have created a "domain.net" account. Assuming that Postfix is properly set up to deliver to the specified accounts, which will be held under the "domain.net" directory, will this work in the dovecot.conf file: # default_mail_env = maildir:/var/mail/%d/%u or do I need to modify it somehow? -- Gerard

[Dovecot] Full text search indexing
by Timo Sirainen 10 Dec '06

10 Dec '06

There are now two full text search backends in CVS HEAD: - squat: My own full text search index based on ideas from Cyrus Squat indexes. Supports substring searches. - lucene: Uses CLucene library. It should be pretty easy to add support for more backends. As I've explained a couple of times already, IMAP RFC says that searches are done by matching substrings, so the Lucene backend isn't fully RFC compliant. Currently it's anyway used to optimize standard SEARCH BODY/TEXT rules, but I'll probably make it optional and instead add new X-NONEXACT-BODY/TEXT rules. Then it will be possible to use both Lucene and Squat backends to optimize different searches (eg. Lucene for your modified webmail and Squat for standard IMAP clients). The Squat index finally worked better than I thought. It has two limitations: - Search strings must be at least 4 characters long - Those 4 characters can't contain spaces So eg. searching for "ip add" doesn't work, but "ip addr" does. By "doesn't work" I mean it fallbacks to the slow old way of going through all the mails. The space limitation exists only because I thought that such searches are going to be rare, and this reduces the index size by 20-50%. So the Squat indexing works by looking at 4 character blocks. So when searching for "address": - Get a list of UIDs for "ress" - Filter out UIDs which don't appear for "dres" - The same for "ddre" and "addr" - Open all the messages that are left in the UID list and drop out the messages where the whole "address" word doesn't exist. I think searching the words backwards usually finds fewer hits and makes the search faster. As for the index sizes, indexing my dovecot mbox with 7495 messages and size of 32479980 bytes it produced: dovecot.index.search : 2166526 bytes dovecot.index.search.uids : 6074155 bytes So that's about 25% of the mailbox size. Last I checked, Cyrus Squat took about 120% (with different messages). Anyway as you can see the uids file is larger than the search trie file, so the number of messages is more important in determining the index size than the number of bytes. The initial index build is pretty slow, but adding new messages to the existing index should be pretty fast. The new messages aren't indexed until client does a SEARCH BODY/TEXT. I'm not sure if the messages should be optionally indexed immediately as they're seen (or even added by Dovecot LDA). Oh and another difference to Cyrus Squat is that Dovecot's version indexes 16bit characters and not bytes. So non-English messages get indexed much more nicely. If you want to try this yourself, you'll need to add: protocol imap { .. mail_plugins = fts fts_squat } plugin { fts = squat }

In the > mean time this user is trying to establish pop3 on a 24/7 basis $-) If you are not selective on which users get the message (i.e. you want this notice to go out to all POP users), then you can do what the previous poster said and make a read-only mailbox and redirect the user's INBOX to this file (via symlinks, or dovecot.conf or what-have-you). This is probably the easier route. Another easy solution might to use tcp-wrappers and reply to all connections to port 110 with -ERR Please contact ... Some (most?) mail readers will pop this message to the user. Another solution which I employed (for another reason) is to make your own mini-dameon which enters into a fake POP session. Just allow any authentication information and server up your fake notice. The POP3 protocol is fairly simple and you only have to implement a small subset of commands: user(noop), pass(noop), list, stat, retr, top, rset(noop), noop(noop), dele(noop), quit. I return a "OK" for most of these commands and most of them are noops. I wrote a patch for qpopper to do this but you could probably modify the source to make it a stand-alone server: http://www.math.ubc.ca/~tam/Software/Qpopper.M2W/m2w.patch For the curious, the reason why I had to make this bizarre patch: http://www.math.ubc.ca/~tam/Software/Qpopper.M2W/ Joseph Tam <tam(a)math.ubc.ca>

Or, you can block the particular user at the firewall. Or if you have a special someone who is allowed POP3 you can give them an alternate port to login with, and not listen at all on port 110 if it really bothers you. -- Kenny Dail <kend(a)amigo.net>

[Dovecot] specifying INBOX with maildir for mail_location
by Post Master 08 Dec '06

08 Dec '06

I'd like to store all of my mail in maildir, but I want to store the inbox and indices on fast storage and everything else on deep storage. Does the following configuration value for mail_location accomplish this? mail_location = maildir:/data/deep/%Ld/mail/%Ln:INBOX=/data/fast/%Ld/mail/%Ln:INDEX=/data/fast/%Ld/indices/%Ln ------------------------------------------------------------------------ If not, does the following configuration accomplish this with namespaces? mail_location = maildir:/data/fast/%Ld/mail/%Ln:INDEX=/data/fast/%Ld/indices/%Ln namespace private { separator = / inbox = yes hidden = yes prefix = location = } namespace private { separator = / hidden = yes prefix = ??? location = maildir:/data/deep/%Ld/mail/%Ln/??? } ------------------------------------------------------------------------ Actually, I can't quite finish the namespace configuration. I'd like to set something like: prefix = * location = maildir:/data/deep/%Ld/mail/%Ln But I suspect the '*' won't actually match everything, and even if it did, I suppose it would also match the inbox. I began with listing any and every typical folder in its own namespace like: namespace private { separator = / hidden = yes prefix = drafts location = maildir:/data/deep/%Ld/mail/%Ln/drafts } namespace private { separator = / hidden = yes prefix = templates location = maildir:/data/deep/%Ld/mail/%Ln/templates } namespace private { separator = / hidden = yes prefix = sent location = maildir:/data/deep/%Ld/mail/%Ln/sent } and so on, but that doesn't seem very elegant. Also, namespaces scare me for client compatibility. Am I missing something obvious?

[Dovecot] Extra inbox problem
by Stephen Allen 07 Dec '06

07 Dec '06

One of my users (who uses Outlook) has lost all her folders that were inside her INBOX. She collects her mail by IMAP. I have confirmed that she has no folders in her INBOX. However, if I use Pine, I can see a couple of extra folders, "INBOX." and "Junk Email." that I don't think should be there. There already folders by that name but without the dot on the end. If I look in "INBOX." I can see the folders she's missing and the folder that they contain etc. I backed up and moved the files listed under .maildir, and Dovecot recreated them, but it made no difference to the problem. I don't understand why those extra folders appear in Pine, but not Outlook. Kind regards, Steve

[Dovecot] rc15 dumped core
by Hans Morten Kind 07 Dec '06

07 Dec '06

We have been running rc15 since Sunday experiencing no trouble, but today one user crashed. rc15 on Solaris-5.9, the server had app 6GB free memory at the time of the crash, app 70% idle running with an avg.load at 4 of 8 processors available. The USER's INBOX was quite smooth, app 13MB containing 320 messages. The core dump was accompanied with these log-entries: Nov 23 2006 12:27:00 [local3.error] IMAP(USER): Corrupted index cache file imapindex/USER/.imap/INBOX/dovecot.index.cache: invalid field header size 12:28:23 [local3.error] IMAP(USER): mremap_anon(1164206080) failed: Not enough space 12:28:23 [local3.error] IMAP(USER): mremap_anon(8192) failed: Invalid argument 12:28:24 [local3.error] child 17510 (imap) killed with signal 10 12:28:25 [local3.info] imap-login: Login: user=<USER>, method=PLAIN, rip=000.177.00.21, pid=19178 We have been observing a few of the 'invalid field header size' messages while running rc15. But as this USER, others seem to recover after the message has been logged. The messages from 'mremap_anon' have never been seen before. Actually '1164206080' looks very much like a timestamp, differing 75223 seconds from the time of the crash ... spooky I will start running the supplied code for memory debugging on this user and I enclose a back trace from the crash. The interessting stuff from the back trace is probably that hdr (and so cache->hdr) is 0xffffffff so that hdr->continued_record_count gives no sense (Cannot access memory at address 0xb) but cache->index->map->records_count is 320 Still on this and another server running rc15 (Sol5.8), we have thousands of happy users beeing served very fast by Dovecot. hmk

[Dovecot] rc15 sort bug

07 Dec '06

Hi, ive come across what looks like a bug in how dovecot sorts the mail when sorting on subject. We noticed this on our current beta8 version, and I can also reproduce it in rc15. One of our customers has hundreds of emails with subjects like this: Subject: 20060823 Kanglaonline-NSCN(IM) cadres violating Tml truce: NSCN(K) Subject: 20060824 LSE - Shell jv denies 3.2 bln usd fraud claims by Nigerian parliament Subject: =?iso-8859-1?Q?20060824_Ibinda_-_Onze_militares_angolanos_mortos_em_comba?= Subject: =?iso-8859-1?Q?20060824_Gingaocultural=2C_VoA_-_Deputados_constatam_clima?= Some of the Subject lines are encoded, some arent. All the encoded Subject lines end up being sorted wrong. Here is a UID SORT output: * SORT 3 4 5 10 20 26 27 28 29 30 33 35 36 37 39 43 44 46 47 58 59 60 83 85 87 8 8 89 90 93 112 113 115 116 118 124 126 127 130 131 132 134 135 137 139 140 141 1 79 205 206 208 209 210 211 212 215 217 226 237 238 240 241 250 282 283 285 291 2 92 293 314 315 316 317 318 319 320 321 328 329 330 337 355 377 378 379 380 381 3 82 383 384 385 407 411 413 423 427 398 409 367 374 376 371 348 372 353 369 400 3 66 352 396 50 370 354 402 347 404 412 415 356 419 408 414 420 388 243 251 21 386 31 1 2 7 6 9 8 349 13 11 12 32 15 34 14 16 22 23 18 17 25 24 19 45 38 48 397 40 3 49 41 40 42 421 56 82 54 53 51 55 52 57 86 63 64 61 62 65 67 71 66 77 76 72 74 75 68 70 84 69 73 80 81 78 79 91 92 128 133 94 97 98 95 96 242 100 102 99 101 1 03 249 114 105 104 247 108 106 107 109 111 375 110 117 387 322 129 125 136 122 1 21 123 144 143 120 233 119 138 142 166 214 149 156 153 155 152 158 159 165 162 1 51 157 154 148 150 160 145 146 147 161 410 418 417 163 164 172 168 173 171 170 1 69 167 178 174 175 176 177 180 184 181 182 186 183 185 213 389 230 232 207 231 2 29 246 216 234 248 225 390 189 275 277 187 340 204 200 197 195 194 192 193 191 1 99 198 196 416 188 190 391 350 201 218 202 245 203 361 228 279 239 220 224 221 2 23 222 235 244 219 280 236 281 278 252 254 304 351 256 257 253 255 274 276 273 2 64 265 263 261 262 258 272 260 259 294 357 227 290 269 286 358 266 270 271 268 2 87 267 288 284 289 359 310 309 307 303 305 306 373 295 300 297 298 296 299 311 3 12 302 308 301 313 332 325 326 324 323 333 346 327 331 362 334 339 335 336 360 3 41 344 338 345 342 343 401 365 392 363 368 399 394 405 395 406 422 424 425 426 4 29 428 393 For instance, UID 112 is an encoded subject and should appear after UID 111 later on in the output.

[Dovecot] Pre-rev1 compatibility

What about adding some compatibility for pre-rev1 IMAP4 clients which are still around (e.g., CDE dtmail, even in Solaris 10)? Especially, the understanding of command FETCH message (... RFC822.HEADER.LINES (parameters)) instead of FETCH message (... BODY.PEEK[HEADER.FIELDS (parameters)]) (with correspondingly changed replies) would be desirable and shouldn't be too difficult to implement.

[Dovecot] quota question
by Kenny Dail 06 Dec '06

06 Dec '06

I'm afraid I'm being a little confused by the whole quota setup with dovecot. I see references to quotas about, but I'm not certain how many of them apply to 1.0rc15. I currently have the conf setup as indicated on http://wiki.dovecot.org/Quota So, in my setup, I'm using Postfix, Maildrop and Dovecot. Mailstore is on NFS. Dovecot is handling the pop3 and imap connects. There seems to be some trouble in the quotas because Courier counts quota one way and Dovecot in a different way. Quotas are stored on a per user basis in the MySQL DB. The trouble I'm getting is that very frequently the quota being reported is quite different from reality. This leads to erroneous over quota delivery errors. So what is necessary to make sure the quotas work as they are supposed to in my environment? Once again thank you very much for your help. -- Kenny Dail <kend(a)amigo.net>

Hey guys, Running rc15, I have maildir quotas working with deliver - however I seem to be unable to get the maildir quota ignore option to work. Am trying to ignore a user wide directory "Maildir/Filtered/", where detected virii/spam gets sorted to. Does deliver take notice of the maildir ignore option ? Applicable line from dovecot-sql.conf: user_query = SELECT CONCAT('/var/mailstore/',Domain,'/',Partition,'/',Email,'/') AS home, CONCAT('maildir:/var/mailstore/',Domain,'/',Partition,'/',Email,'/') AS mail, 5000 AS uid, 5000 AS gid, CONCAT('maildir:storage=10240:ignore=Filtered') AS quota FROM Mailbox WHERE Email = '%u' AND Status = '1' As a side note is there a configurable variable/template to set the "Your message was automatically rejected by Dovecot Mail Delivery Agent" messages. Or is customization only possible by modifying the source ? Regards __________________________________________ Dean Manners

[Dovecot] maildirsize update error
by Maykel Moya 04 Dec '06

04 Dec '06

According to [1], Trash is a reserverd folder name. When moving a message to it, maildirsize should be update with a negative byte count. If I move a message from any folder to Trash, maildirsize gets two lines, one positive and one negative. The problem is that a user can't move messages to Trash while being overquota because the positive entry goes before the negative. I'm using dovecot-1.0rc14.

Will it know which files are mbox folders, so it doesn't try to convert other files in the home directories? When are the e-mails converted? Are the old files deleted? Is this configuration snippet valid? default_mail_env = maildir:~/Maildir convert_mail = mbox:~/:INBOX=/var/mail/%u If I can do that, it seems like an easy change. Andrew

[Dovecot] Performance Tuning Recommendations for Dovecot
by Jack Stewart 04 Dec '06

04 Dec '06

Hi, I'm wondering if anyone has some performance tuning recommendations for Dovecot. We are currently building a series of department e-mail/imap servers and we will be replacing our central core in the coming summer. The department servers are relatively small 100-200 users and the central server is modest - around 7000 accounts. They will be using local filesystem or SAN for the backend storage. So far, enabling hard links seems to be a big win. I'm curious if there are others out there that people have found useful. I am considering putting the indexes on memory disks but I haven't scoped out the requirements for the central system yet (i.e. it is unclear to me how large the index will be for approximately 13 million messages take take up roughly 800GB of disk space. Any pointers are greatly appreciated. Sincerely, ---Jack Stewart

[Dovecot] Deliver bounces messages if can't write to logs
by Francisco Reyes 04 Dec '06

04 Dec '06

I am new to using Dovecot's LDA deliver. One particular item which I think may be improved.. If one uses logs instead of syslog and if Dovecot/Deliver can't write to the logs, mail is bounced. In contrast if it can't connect to the authentication socket auth-master, it defers. Shouldn't mail be deferred if access to the log files fails due to rights? Doesn defer makes more sense than to bounce in this case? In all likelihood it was postfix that bounced/deferred, but I believe it has to do with what response postfix got from deliver.

[Dovecot] Enabling different quota limits for different users for /etc/passwd as userdatabase on FC3
by ankush grover 04 Dec '06

04 Dec '06

hey friends, I am running my company's mail server on FC3 which comprises of Postfix + Dovecot + MailScanner + Clamav + Squirrelmail + MailWatch + Spamassassin. I am using Dovecot 0.99.13-3 version on FC3 and I want to implement Quota limits for the users. I am using userdatabase as /etc/passwd file (auth_userdb = passwd ) and password database as pam(auth_passdb = pam) for dovecot. I read the documentation of dovecot but the quota example for /etc/passwd is missing. I want to have different quota limits for different users for example Quota limitation will depend upon the users, well there will be a global quota limit which will takes place if there is no limit specified for that particular user. Can anybody guide me how to configure quota's for different users in dovecot for /etc/passwd as userdatabase and pam as password database. Please let me know if you need any further inputs. Thanks & Regards Ankush Grover

[Dovecot] / and . in folder names
by Magnus Holmgren 04 Dec '06

04 Dec '06

Right now, trying to create folders with "/" or "." in their name can yield strange results, because Dovecot simply turns every occurrence of the current folder hierarchy separator in a folder name given by the client into a "." (or so it seems). If the folder separator isn't ".", clients can try to create folders with names containing ".", and Dovecot will convert those "." back to the folder separator on listing. It will look like there is an intermediate folder, but Dovecot is unaware of it. If the folder separator isn't "/", clients can try to create folders with names containing "/", which will simply fail. Judging from to http://www.courier-mta.org/?maildir.html, Courier encodes "." and "/" in the names of the directories the folders are stored as on disk. This means that that of "." and "/" that isn't the folder separator can be used in folder names, but it also means that Dovecot has to be able to perform the recoding. Has any thought been given to this? -- Magnus Holmgren holmgren(a)lysator.liu.se (No Cc of list mail needed, thanks) "Exim is better at being younger, whereas sendmail is better for Scrabble (50 point bonus for clearing your rack)" -- Dave Evans

[Dovecot] Deliver Root Setuid
by Láďa 03 Dec '06

03 Dec '06

Hi, I just configured my Postfix installation to deliver via Dovecot LDA. But because I use separate uids for virtual domains I had to set deliver to be setuid root. Altough I find this as frequent answer to this problem with deliver LDA I am not a 100% sure - basically because I try to avoid root setuids as much as I can. What should be better solution - to have all mailboxes with one owner or this setuid binary? My main reason for separate uids was filesystem quotas for whole domain. But my mail partition resides on XFS so I can do the same with directory quotas and I also noticed changes in quotas which should be also per domain in some next release or with patch. Thanks for any advice and also thanks for all great work on Dovecot. Láďa

[Dovecot] [IDEA] Shared Folders via LDAP Lookups
by Gavin Henry 03 Dec '06

03 Dec '06

Hi All, We've been thinking a lot about the 2 different ways dovecot implements shares; namespaces and symlinks. We currently use the symlink version for our clients and they use the create_dovecot_shares.pl tool we did at: http://dovecot.org/tools/ Our idea is either in the namespace declaration or if a folder has a dovecot-shared file/symlink, have a ldap lookup defined in say, dovecot-ldap-shares.conf or dovecot-ldap.conf, that queries a dn and looks for memberUID or a group dn, then those uids/groups can get into the IMAP maildir. Obviously the original folder would need to be owned by some predefined user, e.g dovecot etc. Then it's just a simple matter of adding a new memberUID/group to the share listing. We can do a custom dovecot.schema if needed (for say a dovecotShare attribute etc.), as long as we get dovecot a Private Enterprise Number from: http://www.iana.org/cgi-bin/enterprise.pl If Timo hasn't already got one, but I can't see one in: http://www.iana.org/assignments/enterprise-numbers Thoughts? -- Kind Regards, Gavin Henry.

[Dovecot] small mbox and index files problem
by Paul Shackel 03 Dec '06

03 Dec '06

Dovecot version: 1.0-0_33.rc15 built by atrpms Operating system: Redhat EL4 CPU architecture: x86 Filesystem you used: mailboxs via nfs to fileserver using xfs Just upgraded from 1.0-0_20.rc7 to 1.0-0_33.rc15 built by atrpms and we had previously set mbox_min_index_size to 1024 (1Mb) and now all mailboxes (mbox format) that are under this size are not able to be opened and throw an "Internal error occured. Refer to server log for more information." using either Thunderbird or Outlook Express, both of which are recent versions. The small mailboxes can be opened after turning mbox_min_index_size setting back to 0, at which time it creates indexes. There is nothing in the syslog file. I am looking in the right place as I can see the dovecot startup message. paul --

Re: [Dovecot] dovecot:IMAP(user) killed with signal 6
by Spil Oss 03 Dec '06

Thanks Timo! Since I've been running rc10 again dovecot stopped aborting. By the way, when I used the create_shares.pl script, it created a symlink for every file in the directory to be shared. Simple symlinking the dir seemed to 'almost' work but for the keyword file errors. Upgrading to rc15 fixes the problem as well, the Permission Denied message still comes up, but dovecot no longer aborts. Will try the create_shares.pl script again and see where my symlink-config is wrong. FWIW I wouldn't want any undocumented behaviour in dovecot just because I'm a stupid twat... Kind regards, Spil.

[Dovecot] Problem with rc10, perhaps 11-15
by Steven F Siirila 03 Dec '06

03 Dec '06

I don't recall if I mentioned this on the list, but when you are configured with mbox format, and a user has no Dovecot index files yet, and the config is such that mbox_min_index_size is set to non-zero, non-default (128 in my test case), dovecot deliver fails. Commenting out "mbox_min_index_size" fixed the problem, and the indexes then get created. This problems exists in RC10 -- I'm mentioned this in case it still exists in the latest revs so it can get fixed before release. -- Steven F.

[Dovecot] IMAPS works, IMAP does not
by Peter Lindgren 03 Dec '06

03 Dec '06

Hello! I have a simple (I think) problem. I have had IMAPS working fine for a long time. Now I want to start to use IMAP and STARTLS, since my mobile SonyEricsson P900 can't use IMAPS directly. But I can't connect even locally to the IMAP port (143), no-one listens there according to netstat (*.imaps is in LISTEN state). I have the following settings in my /etc/dovecot.conf: protocols = imap imaps ssl_cert_file = /etc/ssl/dovecotcert.pem ssl_key_file = /etc/ssl/private/dovecot.pem disable_plaintext_auth = no login_user = _dovecot login_greeting = Dovecot@casiopea ready. mail_read_mmaped = yes mmap_no_write = no protocol imap { login_greeting_capability = yes } protocol pop3 { } auth_verbose = yes auth default { mechanisms = cram-md5 digest-md5 passdb passwd { } userdb passwd { } user = root } I have restarted (SIGTERM) dovecot to be sure that dovecot is restarted. I still run 1.0beta3 on OpenBSD. TIA, Peter -- Peter Lindgren, dataingenjör E-post: peter "at" norrskenkonsult punkt com http://www.norrskenkonsult.com

[Dovecot] shared folder
by T. Horsnell 03 Dec '06

03 Dec '06

The dovecot wiki says: The only way to implement shared folders with Dovecot 0.99.x is to create a "shared userid" which all of the users log in to read mail. Does this mean that folders owned by that shared uid can be *simultaneously* manipulated by multiple users logged in to that shared uid? This doesnt seem to be the case on my dovecot-0.99.11-4.EL4 system, and before investigating further I just wanted to check whether it should be possible or not. Cheers, Terry.

[Dovecot] Nested folders in FS supported yet?
by Sweth Chandramouli 03 Dec '06

03 Dec '06

The last time I checked, dovecot didn't support having nested IMAP folders be implemented via actual nested maildir folders in the filesystem, but that feature was on the "someday maybe it'll happen list", IIRC. I can't find any recent mention of that feature or its absence on the web or in the list archives; is it still on the someday list? (If it isn't implemented yet, does anyone know of an IMAP server that DOES support it?) Thanks, Sweth. -- Sweth Chandramouli sweth(a)ethicalhomes.com - http://EthicalHomes.com/ Thinking about buying a home, but feel like the local real estate market has left you behind?

[Dovecot] Can't remove folder
by Leroy van Logchem 03 Dec '06

03 Dec '06

Hello, Here is a 'me too' somewhat like: http://www.dovecot.org/list/dovecot/2006-January/010759.html Example scenario: /u/username/Mail/subfolder/somebox subfolder is a directory somebox is a mbox When I use Thunderbird's "Delete folder" function on the somebox the message appears: "Target mailbox doesn't allow inferiour mailboxes". Thunderbird, by default, tries to move it to Trash instead of deleting it directly. When I change the preference to "Remove it immediately" it works. Which component is at fault here: - limitation of a mbox only setup? - thunderbird should know - limitation of the imap protocol to advice the client it's mbox backed - feature of dovecot, could it be fixed or worked around somehow -- Leroy

[Dovecot] Logging
by Steven F Siirila 03 Dec '06

03 Dec '06

In trying to determine why someone was unable to use port 110 w/STLS (POP) I had great difficulty finding the session in which the user switched to this port from using port 995. This is because Dovecot does not log any port number information. Furthermore, it isn't obvious to me if it logs whether a session was negotiated SSL (via STARTTLS w/IMAP or STLS w/POP) or started out SSL (ports 993 and 995). If this seems reasonable, I can whip up a patch to log this information. However, I'd rather see Dovecot 1.0 released first. -- Steven F.

[Dovecot] authentication
by eric 03 Dec '06

03 Dec '06

Good evening from Aotearoa; First some details: Clients are all Outlook2003 on XP yawn Server is Suse 9.3 Samba, postfix, fetchmail and dovecot 1.0 rc13 I succesfully installed Dovecot on my test network at home, but at the job site its a mystery. I seem to be able to get one client to authenticate but not another. And only if i created a password file consisting of logins and no passwords. Dovecot won't use standard unix passwd successfully.

[Dovecot] Problems using Squirrelmail / Dovecot / Sendmail / Fedora Core 6 - ERROR: Connection dropped by IMAP server
by Alexander Lapajne 03 Dec '06

03 Dec '06

Hello I just installed Fedora Core 6 and I'm having problems with SquirrelMail. I'm using Squirrelmail/Dovecot/Sendmail and when I log into Squirrelmail and try to view any folder that contains any messages I get: ERROR: Connection dropped by IMAP server. Query: SORT (ARRIVAL) ISO-8859-1 ALL Now, I've tried to disable server side sorting in Squirrelmail but that only leads to a new error message: ERROR: Connection dropped by IMAP server. Query: FETCH 1:* (FLAGS UID RFC822.SIZE INTERNALDATE BODY.PEEK[HEADER.FIELDS (Date To Cc From Subject X-Priority Importance Priority Content-Type)]) I'm using the default setup and POP3 mail is working. Using Thunderbird I can read email using POP3. So the problem only appears when using Squirrelmail. I had the exact same setup in Fedora Core 5 and it was working perfectly. Same config files and everything. _________________________________________________________ Flyger tiden iväg? Fånga dagen med Yahoo! Mails inbyggda kalender.

[Dovecot] %s service variable substitution
by Jim Horner 02 Dec '06

02 Dec '06

I'm using 1.0rc15. We switched over to using deliver LDA and using dovecot's sasl implementation for postfix... In our ldap configuration we were using (similar for password filter) user_filter = (&(objectClass=mailUser)(mail=%u)(mailSettingValue=%s)) The problem is these new services, namely deliver and postfix, are accessing the authentication mechanisms and I am not sure what to put in ldap so the %s can match. Each user currently only has a mailSettingValue=IMAP. This can be expanded for multiple entries. Thanks, Jim

[Dovecot] Quota's with Thunderbird
by Richard Mayhew - Nashua Mobile Broadband Division 30 Nov '06

30 Nov '06

Hi, Does anyone know how to get Thunderbird to correctly report the mailbox quota's? I know Dovecot is correctly enforcing the quotas on the mailbox when using Thunderbird, but Thunderbird reports that the "server does not support quota's" when trying to view the usage? Is Thunderbird expecting something different? Viewing the mailbox through Squirelmail, the quota's are reported correctly, so I would thnk that Thunderbird is where the problem lies. Regards Richard

[Dovecot] lmtp: help needed
by Leonardo Lanzi 30 Nov '06

30 Nov '06

Hi all, parsing the mailing list archive, it seems that the lmtp-server will not be developed soon, so I'm looking for someone that could help me in writing one, even if not the best one. That's why: I've just started to study dovecot, as I was recruited, just about forced, to help The System Manager of our University in the global e-mail migration - more than 37'000 users, 440 mailing lists, everything synchronized with administrative databases and so on - from open-vms (yes... you have not sight problems: OpenVMS ... please don't blame us). In particular, we have (we'd like so much) to directly deliver from a front-end load-balanced anti-spam&virus all "good" messages into maildirs, updating at the same time the indexes for dovecot. Our idea is to write an lmtp, possibly not from scratch; we have already a threaded server, recently born as a raw smtp server to test the antivirus and antispam system under heavy load (before to start the migration), that can be converted to lmtp protocol, but we lack of information on the dovecot API for delivering in a "dovecot-way". As often occurs, we have not months to get it done, therefore _any_ kind of suggestion will be very much appreciated. Thank you all for the help, and patience! -- Leonardo Lanzi Department of Physics - University of Florence - Italy -- PS - Examples of help: 1. "The code is self-explaining, but obviously you're too old to learn: accept to be in the mist, and switch to cyrus" 2. "the following n-functions ... of deliver can accept your data from memory and do all the job" 3. "I've already done everything, download it at the following url..." 3a. "I've already done everything, but you must send me, _before_, your smtp stressing server, or all your tests on latency of irq handlers with 2.6 kernel, or at least one 18-year-old scottish-malt-whisky bottle!"

[Dovecot] Subfolders with Thunderbird and maildir?
by Andrew Z 30 Nov '06

30 Nov '06

I setup a test dovecot-1.0-0.beta8.2.fc5 and left most of the settings as the defaults. In Thunderbird 1.5.0.8 Windows, when I tried to create a subfolder named "subfolder" under INBOX, it showed up as the same level a INBOX and with the name "INBOX^subfolder". I was able to manually create a subfolder using "mkdir ~/mail/test_manual_subfolder; touch ~/mail_test_subfolder/blah" and then subscribing to it. That's too much work. :) Now when I try to create a subfolder of a non-inbox folder, nothing happens (not even an error). Screen shot: http://img452.imageshack.us/my.php?image=subfoldersthunderbird15ao6.png The Dovecot system is Fedora Core 5 x86 and an NFS client for /home. I'm considering switching from Trustix, UW-IMAP, and mbox. I'm also considering changing INBOX to a Maildir (not /var/spool/mail/%u). Andrew

[Dovecot] MAILDIR environment
by adcx＠server101.com 29 Nov '06

29 Nov '06

from docs/mail-storages.txt: "Also as a special case, if MAILDIR environment exists, maildir storage is used with the directory specified in it." Forgive me if this seems obvious, but is this talking about setting MAILDIR as an enivornment variable? I have it set on my system in both /etc/profile and ~/.bash_profile: MAILDIR=/path/to/maildir/ export MAILDIR and have confirmed this worked by running 'echo $MAILDIR'. I've logged the user in question out and then in again, as well as restarting dovecot but it still defaults to checking ~/Maildir when the user logs in. Setting the location using default_mail_env is not an option here as I need the fallback behaviour that occurs when default_mail_env is not set. Any advice appreciated.

[Dovecot] Redundant shared mail store?
by Jasper Bryant-Greene 29 Nov '06

29 Nov '06

Hi guys I'm about to embark on a project replacing a legacy single mail server running proprietary software with a cluster of Dovecot servers. We clearly need a shared mail store for these servers, but we are not happy with simply using a server running NFS as this becomes a single point of failure. What have other people used? AFAICT our options are: * A shared block device (Fibre Channel, iSCSI, ATAoE etc) running GFS or similar to allow multiple servers to access it concurrently * Two or more NFS units, either with built-in support for replication of FS changes and failover, or with scripts for achieving this functionality I prefer option 1, although it's expensive. What have other people used? Do we have other options? TIA -- Jasper Bryant-Greene Director Album Limited jasper(a)albumltd.co.nz +64 21 708 334 / 0800 425 286 http://www.albumltd.co.nz/

[Dovecot] Quota problems on uidlist files
by James Nunnerley 29 Nov '06

29 Nov '06

Hi All, Please excuse me for this somewhat a slightly uneducated explanation of a problem we are experiencing. I'm more a web developer rather than a sysadmin, and have only recently been looking at how exactly dovecot works. We're having a problem when users/groups quotas are reached on our server platform. Our platform bases quotas on groups - i.e. domains, so a single user has a user username and group of their domain; and the domain has a set amount of space available. This means that if they then try and access their email, via either imap or in most cases webmail, it would seem that dovecot is unable to create the dovecot-uidlist file - which makes complete sense, because it's running as that user and under the group as detailed above.. We've tried changing a pre-existing file to have group ownership of nobody, but from what we can gather, this file is not actually updated, but deleted and recreated when changes occur. One solution would be to take the dovecot-uidlist file out of the mail directory structure, on which the quotas are enforced, but this is not configurable in dovecot. Alternatively, having someway of changing to ownership of the file would also get around this problem. Does anyone have any experience of either a work around for this, or something which we can change in dovecot that will allow users to create a dovecot file, even if they are over quotas? Many thanks James James Nunnerley Applications Developer Namesco Limited

[Dovecot] Authentication
by eric 29 Nov '06

29 Nov '06

Try as I may, I cannot get Dovecot to allow anything but blank passwords listed in a custom file I made for the purpose. It will not recognise anybody in passwd. Only using POP3 on an internal network so little danger of incursions. Once I created a password file with user names and no password, one user could login (from Outlook 2003) but another could not. Telnet test also fails to authenticate. I have allowed the group to write to the /var/spool/folder Syslog simply showed authentication failed. Relevant bits of my config: disable plain text = no mail extra group = users pop3 uidl format %08Xu%08Xv pasted direct from the help I have un commented auth user name characteres mechanisms = plain and I have set auth debug passwords = yes user = root System: Suse 9.3 Dovecot 1.0 rc13 Any ideas? -- John McC

Our users tend to use one of the following: Apple Mail Entourage (basically Outlook for Mac) Outlook Outlook Express Thunderbird and then there's the webmail system we provide. Apple Mail has virtually no limit on messages it will handle. I currently have over 500,000 emails in my Apple Mail. It stores email much like Dovecot; each email is in a separate file. This makes backups a breeze, which a reason to switch to a server that uses maildir. Entourage, Outlook Express and Outlook have problems if the data file exceeds 2GB. This is an ongoing problem and I'm hoping by keeping email on the server, the support headaches will be reduced. I'm not sure what limits Thunderbird has. I use Thunderbird to connect to the main directory for all email and it doesn't seem to have any trouble handling it. Currently, everyone is using POP3 but I want to move to IMAP. (Thunderbird is the only client that connects via IMAP on our systems) The motivation for moving to IMAP is primarily for spam handling. Instead of users contacting us for emails that might be caught as spam, the spam will be moved to a "junk mail" folder. Then the user can peruse the folder themselves to find any legit email improperly categorized as junk. Vacation messages is the other item that is prompting a change. Everyone is screaming for that feature.

[Dovecot] mailadm? authentication vs. authorization?
by David Lee 24 Nov '06

24 Nov '06

Does "dovecot" have anything similar to the UW IMAP "mailadm" group operation? From near the end of: http://www.washington.edu/imap/documentation/RELNOTES.html 'Support for SASL authentication identity vs. authorization identity in the IMAP and POP3 servers. If the user indicated by the authentication identity is in the "mailadm" group, he may specify any authorization identity and get logged in as the authorization identity user.' This allows an email administrator (member of group "mailadm") to sort out problems in a user's mailbox as that user identifier. (We try to train our users not to reveal their password to anyone, not even to our own staff. But sometimes, as staff, it is very useful to be able to do operations as a particular user to diagnose a problem.) -- : David Lee I.T.

[Dovecot] Two email accounts writing to one nfs shared home directory
by John McDonald 23 Nov '06

23 Nov '06

I use dovecot as a local imap server on my desktop machine due to the fact that my workplace only support POP3. I use fetchmail to pop, postfix to deliver, and dovecot for client access. At present I have a single email account which is the same as my system login and have postfix and dovecot setup to use ~/Maildir. The home directories on our system are served from a central file system, using nfs, which has full backup/disaster recovery policy implemented. I now need to setup a second separate email account for a specific task. Our sysadmins have setup this account for me on the POP3 server. The problem is that this account does not have a home directory on our system and therefore I can't write to ~/Maildir. What I would like to do is setup the same type of system for this second account without necessitating the creation of a home directory. That is, I would like a second Maildir folder in my own user account to which this second email account's messages are delivered. This way I will have full backup of the messages. What is the most straightforward way of achieving this? (or can it be done at all?) Thanks for the help. Regards, John McDonald.

[Dovecot] dovecont.conf and "Evolution Mail" configuration
by maria.freixes_graells＠alcatel.es 23 Nov '06

23 Nov '06

Hello people!! First, thanks very much to Ejay Hire and to John Peacock for your quickly answer!! Now, I've dovecot installed, I downloaded the source and I compiled them. It's running ok now. But.....as I am new in all these issues I have some problems with the configuration. I have a user called "webmaster" that have a mail into /var/spool/mail, I want to redirect these mails to the "Evolution Mail" program from my Linux Desktop. I have doubts in two ways: 1.- Is the dovecot.conf file correct? 2.- Are the "Evolution Mail" setting correct? Evolution Account Settings: Name: webmaster(a)bar.ses.alcatel.es Full Name: webmaster Email Address: webmaster(a)bar.ses.alcatel.es Server Type: POP Host: 159.23.98.66 Username: webmaster Server Type: SMTP Server Configuration: 159.23.98.66 ## Dovecot configuration file # If you're in a hurry, see http://wiki.dovecot.org/QuickConfiguration # '#' character and everything after it is treated as comments.

Exception to this are paths, they're just examples with # the real defaults being based on configure options.

This is the same as the old default_mail_env # setting. The default is empty, which means that Dovecot tries to find the # mailboxes automatically. This won't work if the user doesn't have any mail # yet, so you should explicitly tell Dovecot the full location. # # If you're using mbox, giving a path to the INBOX file (eg. /var/mail/%u) # isn't enough. You'll also need to tell Dovecot where the other mailboxes are # and where Dovecot can place its index files. This is called the "root mail # directory", and it must be the first path given in the mail_location setting. # # There are a few special variables you can use, eg.: # # %u - username # %n - user part in user@domain, same as %u if there's no domain # %d - domain part in user@domain, empty if there's no domain # %h - home directory # # See doc/variables.txt for full list.

Shared namespaces are meant for user-owned mailboxes which are # shared to other users, while public namespaces are for more globally # accessible mailboxes. # # REMEMBER: If you add any namespaces, the default namespace must be added # explicitly, ie. mail_location does nothing unless you have a namespace # without a location setting. Default namespace is simply done by having a # namespace with empty prefix. #namespace private { # Hierarchy separator to use.

[Dovecot] Which version of dovecat I must use quit mysql 14.12 5.0.24a?
by maria.freixes_graells＠alcatel.es 22 Nov '06

22 Nov '06

Hello everybody!! I'm new on linux machine configuration, and I have a question related to product versions. We've Linux seweb1 2.6.9-5.EL installed, but instead of install the mysql product from "Red Hat Interprise Linux 4" CD what is mysql-0:4.1.7-4.RHEL4.1.i386, we installed: *mysql 14.12 5.0.24a *So, now, when we tried to install dovecot, it needs mysql-0:4.1.7-4.RHEL4.1.i386, perl-DBD-MySQL-0:2.9004-3.1.i386 and postgresql-libs-0:74.6-1.RHEL4.2.i386. I don't want to install these packets from mysql because I'm afraid to crash the mysql that we've now working...... So, my question is, what I need to do in this case? Can I install the mysql CD version without interferring to our actual BD working: *mysql 14.12 5.0.24a? *Or....Which version of dovecot we must install in order to work with *mysql 14.12 5.0.24a. *I would be very gratefully if you could help me, beacause we afraid to crash the BD that is working now, and we don't know how to install dovecot in this case. Best regards, Maria

[Dovecot] assertion failed: (need_space == (uoff_t)-mails[idx].space)
by David King 21 Nov '06

21 Nov '06

I'm running Dovecot dovecot-1.0.r13 on FreeBSD (FreeBSD 6.1-RELEASE- p10). Mail is stored in mbox format (dovecot.conf after the msg). Procmail delivers mail to subfolders under ~/.mail, locking using dotfiles. One folder in particular for one user has an mbox file ~/.mail/Cron. Quite often, I'll see that procmail processes are stacking up because ~/.mail/Cron.lock exists, and they (rightly) refuse to deliver to a locked mailbox. It seems that dovecot is creating these lock files and then dying. The .lock file's contents refer to a PID that, by the time I see the lockfile, doesn't exist. It appears that dovecot is leaving behind the lock files, after exiting with a signal 6 (sometimes 11) and leaving behind messages in /var/log/maillog (and the end of this message). In dovecot.conf I have mail_drop_priv_before_exec = no, but I can't find the core file that I would expect it to dump, so I can't give you a backtrace. Hopefully the assertion in /var/log/maillog is enough. With ~/.mail/Cron perpetually locked, I'm not able to receive mail in this folder, and with any IMAP client that tries to access that folder having the IMAP server shut down, it keeps me from getting mail. Any ideas? # tail /var/log/maillog Nov 11 23:05:32 melchoir dovecot: imap-login: Login: user=<ketralnis>, method=PLAIN, rip=10.0.1.239, lip=10.0.0.1, TLS Nov 11 23:05:32 melchoir dovecot: IMAP(ketralnis): Disconnected: Logged out Nov 11 23:06:52 melchoir dovecot: IMAP(ketralnis): file mbox-sync- rewrite.c: line 405 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) Nov 11 23:06:52 melchoir dovecot: child 16929 (imap) killed with signal 6 Here is dovecot.conf: # cat /usr/local/etc/dovecot.conf | sed -E 's/^(.*)#.*$/\1/' | grep - Ev '(^#|^[ ]*$' protocols = imap pop3 imaps pop3s ssl_cert_file = /etc/ssl/mail-cert.pem ssl_key_file = /etc/ssl/private/mail-key.pem disable_plaintext_auth = no login_user = dovecot verbose_proctitle = yes first_valid_gid = 0 mail_extra_groups = mail default_mail_env = mbox:%h/.mail:INBOX=/var/mail/%u mmap_disable = no lock_method = fcntl mbox_read_locks = dotlock mbox_write_locks = dotlock fcntl mail_drop_priv_before_exec = no protocol imap { login_greeting_capability = yes imap_client_workarounds = delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep } protocol pop3 { pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth default { mechanisms = plain login passdb pam { } userdb passwd { } userdb prefetch { } user = root }

[Dovecot] RAID benchmarks
by Ethan Sommer 21 Nov '06

21 Nov '06

We (a small college with about 3000 active accounts) are currently in the process of moving from UW IMAP running on linux to dovecot running on a cluster of 3 or 4 new faster Linux machines. (Initially using perdition to split the load.) As we are building and designing the system, I'm attempting to take (or find) benchmarks everywhere I can in order to make informed decisions and so that when we need something faster we have something to compare it to. I've looked all over the Internet and I haven't seen very many good benchmarks running on recent hardware for things like this. Even simple things like how different raid levels perform with fast CPUs and really fast disks. We recently got the first of the cluster machines (which has the following specs: (from penguin computing) 2x 1.6ghz woodcrest (so 4 cores total) 2g ram (we may upgrade to more, depending on what we seem to need) 6x 15k SAS 73G hard drives. I've always read that RAID 10 is the RAID of choice for mail, because the checksums take time and whatnot, but on a system that fast I'm sure that's not an issue (which I could see from the cpu usage during benchmarks.) We were also wondering whether RAID6 would be a good option since it would give more redundancy. (raid6 allows 2 drive failures) All tests were run on ext3 with all 6 disks in the raid. Everything is using Linux software raid. I used bonnie++ to run the benchmarks, and here are the initial results we got: Output Input RAID "Per Chr" "Block" "Per Chr" "Block" RAID6 34628, 97983, 23316, 39077 RAID5 39559, 32715, 32036, 52231 RAID10 38816, 229062, 40645, 267418 I assume that mail running maildir (as we intend to do) is somewhere between writing one char at a time and writing huge blocks to fill 4g files. Since the Per Chr values seemed to have maxed out the CPU and we'll have 4 cores available, I tried the same thing running 4 copies of bonnie at once and adding the results. (I worked backwards and didn't bother with raid 6 for obvious reasons) Output Input RAID "Per Chr" "Block" "Per Chr" "Block" RAID5 37465, 37095, 102828, 174263 RAID10 111239, 128287, 93400, 230320 So, if our system is ever running full out, basically disk bound, it should be able to handle about 4X as many writes and at least as many reads using RAID10 than raid 5, and since raid 6 was pretty similar to raid 5 in the first tests, I assume it will be here too. I have the full bonnie results if anyone's interested. I also plan to come up with some basic benchmarks as we start to actually have dovecot working as we want it to. (Possibly using the macs in our labs and XGrid as a "client".. finally a use for that thing :) ) Do people have suggestions as to what to test for a primarily IMAP (+ a little POP) server? I was thinking of doing something similar to http://www.courier-mta.org/mbox-vs-maildir/ which selects a mail box, deletes and expunges a message, fetches a few messages, and then does some searches. Also, while I have the opportunity, are there any other benchmarks I should run? I suppose I could compare dovecot with mbox vs maildir, with indexing and without. Dovecot with indexing but the indexes deleted, etc. I could compare dovecot to uw imap. Anything else? I probably can't justify the time to get cyrus up and running. (I did that a few months ago when deciding which server to use...) Ethan Sommer -- -- Ethan Sommer Systems Administrator Gustavus Adolphus College 507-933-7042 sommere(a)gac.edu

[Dovecot] rc14 and rc15 performance issues
by Jeff A. Earickson 21 Nov '06

21 Nov '06

Hi, I am stuck at rc13 because rc14 and rc15 have both failed to keep up with imap connections on my (slow old) system. I have the problem where if a lot of people check their email at once (like at the top of the hour) then my load goes way up and things slow to a crawl. My setup: Solaris 10 on an E220R, mbox format, imap and imaps only. I also use "login_process_per_connection = no". Any suggestions? Jeff Earickson Colby College

[Dovecot] BUG: passdb checkpassword {} and lastauth file
by Max A 20 Nov '06

20 Nov '06

(Repeat, because on the first message there was no reaction) Hi. If checkpassword interface is used for working with vpopmail, function vpopmail "Record time and ip of last auth attempt" (--enable-auth-logging option for configure) won't work - the file "lastauth" is created in Maildir, but does not contain ip-address. If I had correctly understood, dovecot woldn't have set a enviroment variable TCPREMOTEIP for vchkpw. If changes are made in auth/passdb-checkpassword.c (a patch in attachment), everything will work.

[Dovecot] dovecot and ldap passwords.
by Mauro Sanna 20 Nov '06

20 Nov '06

Hallo. First of all I'm sorry for my bad english. I have a question about how dovecot use passwords. I have all my mail accounts in a ldap database. The user password are stored in form: {crypt}mypasswd. In dovecot-ldap.conf I have default_pass_scheme = CRYPT. All is working fine. The problem in the crypt scheme is that I can't have passwords more than 8 characters long. So I've tried to change the type of the ldap passwords in SSHA or SMD5, but in this way the users can't authenticate yourselfs. Dovecot doesn't understand SSHA or SMD5?

[Dovecot] Problem with rc10
by Steven F Siirila 20 Nov '06

20 Nov '06

I just upgraded our test server from rc6 to rc10... ISSUE #1 I noticed that we no longer are getting two "From_" lines. However, the one that was good (had the original sender e-mail address) is now gone. The one with "dovecot.deliver" remains. I attempted to add "-d test" to the mailbox_command line in main.cf as follows: mailbox_command = /opt/dovecot/libexec/dovecot/deliver -d test and things turned ugly and caused Postfix to defer messages: Oct 17 16:31:50 hostname postfix/local[7230]: D14632C9C: to=<someuser@somehost>, relay=local, delay=3.6, delays=3/0.02/0/0.62, dsn=4.3.0, status=deferred (temporary failure) I removed the "-d test" from the Postfix main.cf and the problem went away. So, how do I fix the "From_" lines? ISSUE #2 After upgrading, messages cannot be moved from the INBOX to a folder. Thunderbird claims there was an internal error and to consule the server logs, but I see nothing in the dovecot logs that would indicate what's going on. For example, I attempted to move a message into my Trash folder which did not currently have any index files. Here is a Solaris truss output of that attempt: poll(0x000B4C98, 2, 999) = 0 poll(0x000B4C98, 2, 0) = 0 poll(0x000B4C98, 2, 999) = 1 read(0, " D O N E\r\n", 3323) = 6 write(1, " 2 8 O K I d l e c".., 23) = 23 read(0, 0x000BC5BB, 3317) Err#11 EAGAIN poll(0x000B4C98, 2, 675) = 1 read(0, " 3 0 u i d c o p y ".., 3317) = 27 stat64("/home/sfs/Trash", 0xFFBFF5C8) = 0 alarm(120) = 0 fcntl(6, F_SETLKW64, 0xFFBFF308) = 0 alarm(0) = 120 stat64("/home/sfs/Trash", 0xFFBFF640) = 0 mkdir("/home/sfs/.imap/Trash", 0770) Err#17 EEXIST stat64("/home/sfs/.imap/Trash", 0xFFBFF4C0) = 0 stat64("/home/sfs/Trash", 0xFFBFF4C0) = 0 time() = 1161122396 open64("/home/sfs/.imap/Trash/dovecot.index", O_RDWR) Err#2 ENOENT open64("/home/sfs/.imap/Trash/dovecot.index", O_RDWR) Err#2 ENOENT write(1, " 3 0 N O I n t e r n".., 96) = 96 poll(0x000B4C98, 2, 588) = 0 poll(0x000B4C98, 2, 0) = 0 poll(0x000B4C98, 2, 410) = 0 Someone else using a different IMAP client caused these errors to occur (this is even after I wiped all of their dovecot index files): Oct 17 16:43:11 earth.tc.umn.edu dovecot: IMAP(kor): Corrupted transaction log file /home/kor/.imap/INBOX/dovecot.index.log: invalid indexid (1161121145 != 1156185395) Oct 17 16:43:11 earth.tc.umn.edu dovecot: IMAP(kor): Corrupted transaction log file /home/kor/.imap/INBOX/dovecot.index.log: invalid new transaction log sequence (6 >= 6) Oct 17 16:47:09 earth.tc.umn.edu dovecot: IMAP(kor): Corrupted transaction log file /home/kor/.imap/INBOX/dovecot.index.log: invalid indexid (1161121145 != 1161120959) Oct 17 16:47:09 earth.tc.umn.edu dovecot: IMAP(kor): Corrupted transaction log file /home/kor/.imap/INBOX/dovecot.index.log: invalid new transaction log sequence (2 >= 2) Oct 17 17:05:59 earth.tc.umn.edu dovecot: IMAP(kor): Corrupted transaction log file /home/kor/.imap/INBOX/dovecot.index.log: invalid indexid (1161121145 != 1161120959) Oct 17 17:05:59 earth.tc.umn.edu dovecot: IMAP(kor): Corrupted transaction log file /home/kor/.imap/INBOX/dovecot.index.log: invalid new transaction log sequence (4 >= 4) Here are our non-standard dovecot.conf items: protocols = imap imaps pop3 pop3s shutdown_clients = no syslog_facility = local6 ssl_cert_file = /etc/opt/openssl/certs/dovecot.pem ssl_key_file = /etc/opt/openssl/private/dovecot.pem default_mail_env = mbox:~/:INBOX=/var/mail/%u # Default namespace namespace private { separator = / prefix = location = mbox:~/:INBOX=/var/mail/%u inbox = yes hidden = yes } mail_full_filesystem_access = yes first_valid_uid = 100 max_mail_processes = 8192 mbox_min_index_size = 128 imap_client_workarounds = delay-newmail outlook-idle tb-extra-mailbox-sep pop3_uidl_format = %08Xu%08Xv protocol lda { postmaster_address = postmaster(a)umn.edu mail_plugins = cmusieve } auth_verbose = yes auth_debug = yes auth default { passdb pam { args = session=yes * } } I am now backing out to rc6 for now... we never saw this behavior on rc6. -- Steven F.

[Dovecot] Problems Creating Core Dumps
by Joseph D. Wagner 20 Nov '06

20 Nov '06

Dovecot 1.0.rc15 crashed on my FC4 server, but it didn't create a core dump. Upon further research, I found these lines tucked away in the /etc/rc.d/init.d/functions file: # make sure it doesn't core dump anywhere unless requested ulimit -S -c ${DAEMON_COREFILE_LIMIT:-0} >/dev/null 2>&1 The /etc/rc.d/init.d/functions file is a master file that is referenced by all of the init scripts, so I didn't want to change it. Instead, I created a file /etc/sysconfig/dovecot with the following line: DAEMON_COREFILE_LIMIT=unlimited If I'm reading the /etc/rc.d/init.d/functions file correctly, this should work, but my bash is rusty. I was hoping someone else could check my work. Joseph D. Wagner

[Dovecot] Backtraces without core dumps
by Timo Sirainen 19 Nov '06

19 Nov '06

Since getting core dumps seems to be difficult sometimes, especially with login processes, I've now added code to log the backtrace when Dovecot crashes in some assert check (or some other reason why it decides to abort()). This code works with Linux and Solaris, but I don't know about BSDs. Apparently there exists libexecinfo library which could be used. I think this code could be used to log backtraces also for segfaults, but that's more risky so I didn't do it yet. Maybe it should be done only optionally. If you're interested in trying, the code is now in CVS and in the latest nightly snapshot. When it crashes, it prints something like: Panic: file client.c: line 55 (client_create): assertion failed: (my_client != NULL) Error: Backtrace: ./imap [0x80b2ffa] -> ./imap [0x80b2ecc] -> ./imap [0x805bbb3] -> ./imap(main+0x426) [0x80634a6] -> /lib/tls/libc.so.6 (__libc_start_main+0xc8) [0xb7e53ea8] -> ./imap [0x80566a1] Looks like the symbol name resolving doesn't work all that great. But here gdb will help you: gdb ./imap (gdb) b *0x80b2ffa Breakpoint 1 at 0x80b2ffa: file failures.c, line 126. (gdb) b *0x80b2ecc Breakpoint 2 at 0x80b2ecc: file failures.c, line 185. (gdb) b *0x805bbb3 Breakpoint 3 at 0x805bbb3 (gdb) b *0x80634a6 Breakpoint 4 at 0x80634a6: file main.c, line 223. That went pretty well, except for some reason it couldn't figure out where 0x805bbb3 was. To get some kind of an idea about that, you can do: (gdb) x 0x805bbb3 0x805bbb3 <client_create+467>: 0x90909090 If someone knows better ways to do all of this, please tell me too :)

[Dovecot] Dovecot (unofficial) patches
by Egbert Jan 19 Nov '06

19 Nov '06

Dear list, As a recent dovecot addict, I'm a bit puzzled by the sheer amount of patches available. I have not seen the history of these patches and I could not find a README explainng the patches. Are all these personal wishes/nice to have things or are they (to be) incorporated in dovecot-final? I use rpmbuild to create new rpms from the latest tarball but in that process still several patches are included during the build. I wonder if they are still needed in rc15. I use the orignal spec file (the latest I could find) was created for rc7 and in there I see: Patch2 dovecot-0.99.10-mbox-patch Seems to be to change the order of ./Mail before ./mail Patch3 dovecot-CVE-2006-2414 Overview from CVE db:Directory traversal vulnerability in Dovecot 1.0 beta and 1.0 allows remote attackers to list files and directories under the mbox parent directory and obtain mailbox names via ".." sequences in the (1) LIST or (2) DELETE IMAP command. I'm not a spec file wizard, so I change as less as possible. Unfortunately the maintainer (Jerome Soyer) has never responded to my emails. My server runs Mandriva Official 2007.0 and Postfix 2.3.3 and dovecot rc14 (will move to rc15 soon). TNX EgbertJan (NL)

[Dovecot] TLS timeout with Thunderbird
by Jason Dixon 19 Nov '06

19 Nov '06

I'm trying to get dovecot working with various clients on my new mailserver. I installed the base rc2 that comes with OpenBSD 4.0, then upgraded to rc14 when I ran into problems with TLS and Thunderbird. The server has no problems with Mail.app on my laptop, but any connection attempts from Thunderbird timeout after the TCP handshake. 13:53:41.074438 66.x.x.2.50483 > 38.x.x.248.993: S 3787736038:3787736038(0) win 65535 <mss 1460,nop,wscale 0,nop,nop,timestamp 2064284084 0,sackOK,eol> (DF) 13:53:41.074554 38.x.x.248.993 > 66.x.x.2.50483: S 1565942120:1565942120(0) ack 3787736039 win 16384 <mss 1460,nop,nop,sackOK,nop,wscale 0,nop,nop,timestamp 2681405076 2064284084> (DF) 13:53:41.459434 66.x.x.2.50483 > 38.x.x.248.993: . ack 1 win 65535 <nop,nop,timestamp 2064284084 2681405076> (DF) 13:53:47.028621 66.x.x.2.50483 > 38.x.x.248.993: F 1:1(0) ack 1 win 65535 <nop,nop,timestamp 2064284096 2681405076> (DF) The only thing logged by dovecot is a disconnection event.

[Dovecot] Security hole #2: Off-by-one buffer overflow with mmap_disable=yes
by Timo Sirainen 19 Nov '06

19 Nov '06

Version: 1.0test53 .. 1.0.rc14 (ie. all 1.0alpha, 1.0beta and 1.0rc versions so far). 0.99.x versions are safe (they don't even have mmap_disable setting). Problem: When mmap_disable=yes setting is used, dovecot.index.cache file is read to memory using "file cache" code. It contains a "mapped pages" bitmask buffer. In some conditions when updating the buffer it allocates one byte too little. Exploitability: I think it's going to be pretty difficult to cause anything else than a crash, but I wouldn't say impossible. Only logged in IMAP/POP3 users can exploit this. In theory you might be able to exploit this for other users as well by sending them a lot of specially crafted emails, but this requires knowing what dovecot.index.cache file contains. Normally its contents can't be predicted, although perhaps with POP3 users it gets empty often enough that the exploit could be tried. Then again, the exploit requires having at least 4MB cache file, which won't happen with POP3 users before the mailbox has about 170k mails (if I counted right). With IMAP the cache file is used more, so it's easier to fill the 4MB with for example a lot of To-headers. Workaround: Use INDEX=MEMORY so the cache files aren't used at all. Fix: 1.0.rc15 fixes this. You can also use this patch: http://dovecot.org/patches/1.0/file-cache-buffer-overflow-fix.diff

[Dovecot] I/O leak
by Jim Horner 19 Nov '06

19 Nov '06

I upgraded from rc12 to rc14 last night... sifting through the logs I noticed the following. I point this out since it appears dovecot is in high gear bug-fix mode. This issue is not big for me; I rarely stop dovecot. My init.d script for dovecot is basically stop) killall dovecot imap-login I am guessing there might be a more graceful way to stop dovecot? Or rc14 fixed this? I see in rc14 changelog: - rc13 crashed if client disconnected while IDLEing but only user1 was IDLE.

[Dovecot] quota plugin enhancement request
by Michael Tibben 19 Nov '06

19 Nov '06

Hi am having a small issue with the quota plugin In Squirrelmail when a message is deleted, it seems to be copied to the Trash folder *before* it is deleted from the current folder. However if it is a large message being deleted and the mailbox is close to its quota limit, it means dovecot will deny the copy operation as the quota will be exceeded if the message is copied Because of this, I am wondering if it is possible to have an option for the quota plugin to track, but not enforce the quota. This is because I don't require quota enforcement on IMAP, as Postfix will enforce quota on incoming mail anyway. I hope this makes sense... Michael

[Dovecot] Is "Resource temporarily unavailable" an old problem?
by Ricardo Dias Campos 19 Nov '06

19 Nov '06

Hi. I've installed dovecot recently in a Fedora 5 Linux. It seemed to be OK but I begun to get the message "Can't connect to auth server at default: Resource temporarily unavailable". When I get the message, dovecot hangs. The problem is that "temporarily" is not quite true since the only way to get dovecot running again is to restart it. As a matter of fact, I cannot say that it never recovers. What I know is that it is out for a long, long time. Then a new problem arose: the time between hang-ups begun to diminish. Trying to find why I discovered that the number or dovecot-auth processes was too high (last time I got 169 processes, a lot of them <defuncts>). It seems that, if I kill all these processes, it takes more time before it hangs again. I looked up for messages in the Internet and I found a mail exchange between people from this list. The first hint I got was to upgrade dovecot. As I said, I'm using Fedora 5 and the version distributed with it was dovecot-1.0-0.beta2.7.i386. I upgraded it to dovecot-1.0-0.beta8.2.fc5.i386. I couldn't make any direct relantionship between this versions and the ones in dovecot site so I cannot tell what dovecot version I'm using in terms of dovecot site versioning. Any help is welcome. Thanks, Ricardo

[Dovecot] CHANGE REQUEST: Move config files out of main $sysconfdir
by Brian G. Peterson 19 Nov '06

19 Nov '06

Currently, dovecot places it's config files in $sysconfdir In Makefile.am, this is defines as: confdir = $(sysconfdir) It would be far more friendly to an already overloaded /etc/ directory, and easier to locate the files, to follow the now-common convention and place files in $sysconfdir / dovecot / ... on most systems this would mean: /etc/dovecot/ If there is only a dovecot.conf, it doesn't really matter, but when additional config files get added for ldap, sql, sieve, it starts to add up. Some distributions already make this change, but placing this change in the dovecot core would make it unnecessary for downstream packagers to make a change to the core dovecot distribution files.

[Dovecot] updated gentoo ebuild provides dovecot-sieve
by Brian G. Peterson 18 Nov '06

18 Nov '06

I'm hoping that there are some Gentoo users on this list who will chime in on a bug that is near and dear to my heart. We've created an updated Gentoo ebuild that adds a sieve USE flag and builds dovecot-sieve if the use flag is enabled. The gentoo bug is here: https://bugs.gentoo.org/show_bug.cgi?id=141743 and the ebuild is available as an attachment to that bug, or as a patch attachment (in case you're not running rc14, or just prefer the look of a unified diff) Any gentoo users on this list are urged to install from the ebuild/patch on the bug, and *report back* on the bug or this list, so that the Gentoo dev will know that it's safe to add this to portage CVS. Thank You. Regards, - Brian

[Dovecot] Dovecot LDA, LDAP, Postfix and Spawning programs..
by Jorgen Lundman 18 Nov '06

18 Nov '06

Qmail, when using LDAP, a user can specify delvieryProgramPath, or a .qmail file, to launch something like procmail. Qmail correctly setuid() to the uids set for the user in LDAP, as well as set up the common env vars (HOME, USER, MAILDIR). We moved to Postfix but found that it is quite lacking in the features supported when it comes to "virtual" users. No .forward, and if you set up an alternate transport, they are run as "any user but root, nor postfix, nor the virtual-user's uid". And worse, does not even supply the HOME/MAILDIR values to transport delivery plugin. (Forcing it to getpwnam() or similar). I have an option to make my own setuid program to query LDAP (postmap -q would work), setuid() and call, say, procmail. It has been suggested I can use "maildrop" as it can talk to LDAP. However, I picked "Dovecot" as my pop3/imap program due to an irrational dislike of Courier imap. So, if I tried Dovecot-LDA, would it support the user optionally having a ".forward" file, or perhaps the LDAP attribute deliveryProgramPath, or some other way to filter based on subject/body to sort, and/or forward, mail? If it can use LDAP, will it setuid() to the users uid (as set in LDAP, assuming I cook the LDAP conf entries correctly) when delivering(I'd hope so!) and running external filters? I am still running rc10, which works well but flips out regularly. (Previously mentioned 'too many files open' bug, some leaks in locks) I will upgrade when the LDAP changes are deemed stable.

[Dovecot] two assertion failures
by Mikhail Teterin 18 Nov '06

18 Nov '06

Hello! I was able to overcome the earlier-reported problems (of dovecot treating the standard mailboxes in /var/mail/ as directories) by specifying mail_location (continuing to use the 0.99-era dovecot.conf did not work). Then I started seeing assertion-failures like: file istream-raw-mbox.c: line 499 (istream_raw_mbox_get_body_size): assertion failed: (rstream->mail_size != (uoff_t)-1) these disappeared, when I disabled mmap-access (mmap is limited to 1Gb on FreeBSD/i386), although dovecot-0.99 worked... I can now get to my mail again, but every once in a while the following assertion kills the connection: file mail-transaction-log.c: line 273 (mail_transaction_log_close): assertion failed: (log->files == NULL) Please, advise... Thanks! -mi

[Dovecot] Auth checking also the service
by Alex 18 Nov '06

18 Nov '06

Hello everyone. I'm switching to dovecot from courier-imap and after some problems with Apple Mail client, now everything seems to be fine. The only problem that I have not solved yet is to check also the service (pop3, pop3s, imap, imaps) in the authentication phase. In courier-authlib I do this: MYSQL_SELECT_CLAUSE SELECT username, \ password, \ "", \ 1002, \ 1003, \ '/vmail', \ maildir, \ quota, \ name, \ "" \ FROM mailbox \ WHERE username="$(local_part)@$(domain)" \ AND active=1 \ AND $(service)=1 where $(service) can be pop3, pop3s, imap or imaps. Is it possible to do a similar thing in dovecot? Thank you in advance, Alex

[Dovecot] Help needed
by Ricardo Dias Campos 17 Nov '06

17 Nov '06

Hi. Days ago I sent a message to this list asking for help on a problem that seemed to me to be old: dovecot hangs and dovecot-auth posts log messages like: Nov 16 17:04:39 netuno dovecot: imap-login: Can't connect to auth server at default: Resource temporarily unavailable Nov 16 17:04:42 netuno dovecot: pop3-login: Can't connect to auth server at default: Resource temporarily unavailable Unfortunatelly when this happens the only way to recover is to restart dovecot. After I while I begun to clean the dovecot-auth processes (defunct or not) that remain in the process list and the cycle of running/hunging restart from 1 hang a day until it reaches 1 hang each 10 minutes, when I kill dovecot-auth again. I've seen some days ago some messages related to this problem but they were inconclusive, meaning that they didn't point to a solution. Any help is welcome. Thanks. Ricardo

[Dovecot] LDA Question
by Jeff 17 Nov '06

17 Nov '06

I need some advice about replacing maildrop with the Dovecot LDA. I need to replicate a setup that uses postfix+maildrop+spamassassin. We'll be using Dovecot 1rc13. In the current setup, maildrop reads a file called .mailfilter in each user's folder, then call spamassassin according to the user's preferences. The file is simple, and looks like this -- if ( $SIZE > 20971520 ) { EXITCODE=77 echo "Your email was rejected because it exceeded limit of 20 MB" exit } if ( $SIZE < 26144 ) { exception { xfilter "/usr/local/bin/spamc -u user(a)domain.com" } } exception { to "$DEFAULT/Maildir/" } What is the most straightforward way to have 'Deliver' do the same thing, without changing the way that SA gets called? Apologies in advance if this is a boneheaded question. I've been sorting through Sieve documentation and HOWTOs and I see everything but what I need.

[Dovecot] maildirsize update error?
by Maykel Moya 16 Nov '06

16 Nov '06

According to [1], Trash is a reserverd folder name. When moving a message to it, maildirsize should be update with a negative byte count. If I move a message from any folder to Trash, maildirsize gets two lines, one positive and one negative. The problem is that a user can't move messages to Trash while being overquota because the positive entry goes before the negative. I'm using dovecot-1.0rc14.

[Dovecot] Dovecot tries to create bogus files in /var/mail

The files in /var/mail/ are just that -- files (in the bad old Unix mbox format), and not directories, why is dovecot treating them as directories? Please advise... Thanks! -mi

[Dovecot] 1.0.rc13 released
by Timo Sirainen 15 Nov '06

15 Nov '06

http://dovecot.org/releases/dovecot-1.0.rc13.tar.gz http://dovecot.org/releases/dovecot-1.0.rc13.tar.gz.sig I'll just keep on making new releases now whenever something important is fixed. Hopefully there shouldn't be many left anymore. Most of the bugs fixed in this release were found by stress testing with my imaptest tool (http://dovecot.org/tools/imaptest.c) If you're interested in knowing how perfectly your Dovecot setup works (especially if you're using NFS), you could try the tool yourself also. I still see one crash with mmap_disable=yes, but it's pretty rare. Will see if I get it fixed before v1.0, but it's not that important. + deliver: If we're executing as a normal system user, get the HOME environment from passwd if it's not set. This makes it possible to run deliver from .forward. - Older compilers caused LDAP authentication to crash - Dying LDAP connections weren't handled exactly correctly in rc11, although it seemed to work usually - Fixed crashes and memory leaks with AUTHENTICATE command - Fixed crashes and leaks with IMAP/POP3 proxying - maildir: Changing a mailbox while another process was saving a message there at the same may have caused the changes to not be made into the maildir, which could have caused other problems later..

[Dovecot] 45second delays on log in
by Ben Marsh 14 Nov '06

14 Nov '06

Dear List Members, We have been running Dovecot as an IMAP server for web based access to email for our customers. At the moment, when the server is under load, some users are finding that it takes 45 seconds to log in. I was wondering if any of you guys would have any tips. I would love any information that would help solve or debug this issue. Background information: The server is Debian with kernel 2.4.31. We are running Dovecot 1.0rc6. I have reviewed the change logs and not found any changes pertinent to our situation from rc6 to rc14 (But maybe I am wrong). We have our own auth mechanism. This auth mechanism is the same used across our other products and we haven't had the same delays with the other products. From the information in the various log files the auth mechanism responds almost instantaneously but it still takes a long time for 1 OK Logged in. message to arrive on the screen when using telnet localhost 143 to login. All the mailboxes are stored over NFS. I have taken the step of moving the INDEXES from NFS to a local hard drive using default_mail_env = maildir:%h/mail:INDEX=/spare/%h in the config file. (/spare is a locally attached hard drive). We are using Maildir for our mailboxes so I am told that locking should not be a problem. A mailbox would never be accessed by two machines simultaneously due to the architecture of the system. In order to gain performance increases we also implemented an IMAP proxy between the webmail client and the imap server. This removes delays in all but the first attempt to access webmail. When logging into a user for which login has been verified to take about 45seconds deletion of the large numbers of messages seemed to speed up login for that particular mailbox indicating to me that it was other things that dovecot does after login and before the 1 OK Logged in. message is displayed that takes up all the time. Unfortunately this theory failed when I tried it with other users. I have also analysed the log files. of the 100,000 lines in the log file 49 were messages: Child 12040 (login) returned error 89 54 were messages: imap-login: Master sent reply with unknown tag 18 The actual number at the end of the message changes lots. The frequency of the extended logins would make it extremely unlikely that these messages are the problem. Any help is very much appreciated. Thanks, Ben Marsh

[Dovecot] Question regarding bounce messages on quota full.
by Mustafa A. Hashmi 14 Nov '06

14 Nov '06

Hi all, Using dovecot's LDA (debian backports package: 1.0rc2), users who have exceeded their quota when receiving messages see the message get bounced. This works fine for us, however, the sender is sent a message as follows: -- Start bounce text ERROR This is the Postfix program at host foo.domain.com I'm sorry to have to inform you that your message could not be be delivered to one or more recipients. It's attached below. For further assistance, please send mail to <postmaster> If you do so, please include this problem report. You can delete your own text from the attached returned message. The Postfix program <user(a)foo.domain.com>: Command died with status 11: "/usr/lib/dovecot/deliver" -- End bounce text Is it not possible to specify something a bit more civil for the sender? a "User is over quota" message works much better here. We're already running a script which notifies users when they approach a certain specified % that they're about to exceed quota, however, hoping they all comply is another thing entirely. Any assistance would be much appreciated. Regards, -- Mustafa A. Hashmi mahashmi(a)gmail.com mh(a)stderr.net

[Dovecot] NTLM authentication from Outlook
by Lars Skovgaard 14 Nov '06

14 Nov '06

Hi all I've enabled ntlm authentication in dovecot, and use dovecot sasl in postfix as well. Authentication with ntlm works well from Mac OS X Mail.app, as well as from Outlook Express, but fails with Outlook. Strangely enough, ntml authentication works in Outlook when using smtp (via postfix), but neither from imap or pop3 (both dovecot). As dovecot sasl handles all authentication against a mysql userdb, this strikes me as very strange. I've instructed my clients with Outlook to fetch mail using a ssl- encrypted connection, and to send using ntlm-authentication. This works, but I would like to have ntlm available as an option to all my clients, without forcing them to change mail-clients. I've turned on auth_verbose, auth_debug and auth_debug_passwords, and compared the passwordstring with the one calculated using dovecotpw, and they match. The only odd thing is that the username is returned from Outlook as an all-caps string, so user(a)domain.tld becomes USER(a)DOMAIN.TLD. I don't know if it matters, but I don't think so, as changing the user-login to an all-caps version doesn't solve the problem. Any hints will be most welcome. /Lars

[Dovecot] MacOS X and quota-plugin
by Lars Skovgaard 13 Nov '06

13 Nov '06

Hi all, I've installed dovecot 1.0 rc12 on a MacOS X client system with only a handful of users – all virtual – and would like to enable quotas. I've tried searching the wiki for information on how to do this, but haven't been able to find anything – which is why I turn to the list in hope there's someone out there who can point me in the right direction. I've compiled dovecot without any other authentication than sql and pam, and have enabled ssl, pop3 and dovecot lda (for use with postfix when I get around to it). The installation went smoothly, and dovecot is working great without quota-support. However, when I enable quota- support, the imap child-process crashes. Here's a few lines from the log, slightly altered to protect user-identities: Nov 8 23:05:09 SD-Server dovecot: imap-login: Login: user=<imapuser>, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:09 SD-Server dovecot: child 22662 (imap) killed with signal 11 Nov 8 23:05:09 SD-Server crashdump[22663]: imap crashed Nov 8 23:05:09 SD-Server crashdump[22663]: crash report written to: / Library/Logs/CrashReporter/imap.crash.log Nov 8 23:05:12 SD-Server dovecot: imap-login: Login: user=< imapuser >, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:13 SD-Server dovecot: child 22665 (imap) killed with signal 11 Nov 8 23:05:13 SD-Server crashdump[22666]: imap crashed Nov 8 23:05:13 SD-Server crashdump[22666]: crash report written to: / Library/Logs/CrashReporter/imap.crash.log Nov 8 23:05:16 SD-Server dovecot: imap-login: Login: user=< imapuser >, method=PLAIN, rip=192.168.2.10, lip=192.168.2.2, TLS Nov 8 23:05:17 SD-Server dovecot: child 22670 (imap) killed with signal 11 Nov 8 23:05:17 SD-Server crashdump[22671]: imap crashed Nov 8 23:05:17 SD-Server crashdump[22671]: crash report written to: / Library/Logs/CrashReporter/imap.crash.log This is what I have done in dovecot.conf to enable quota: protocol imap { mail_plugins = quota imap_quota mail_plugin_dir = /usr/local/lib/dovecot/imap } plugin { #quota = dict:storage=10240 #quota = dirsize:storage=10240 #quota = maildir:storage=10240 #quota = maildir:storage=10240 mysql:/usr/local/etc/dovecot-sql.conf #quota = fs:storage=10240 #quota = fs } As you might guess from the lines under "plugin", I've tried a lot of different combinations. If I enable ANY of the above lines under plugin, the child-processes die upon login. When all have been commented out, there's no more crashing – until I try to see how much space is available, then it crashes again. I've tried adding an extra "quota" field to my mysql userdb to handle quotas, but with the same result. mysql-query looks like this (as described in the wiki): user_query = SELECT home, uid, gid, 'dirsize:storage=' || quota_kb AS quota FROM users WHERE userid = '%u' As with the settings in dovecot.conf, Ive tried various combinations of dict, dirsize and so on, but without any luck.

Procmail writes to the folders, but it uses dotlocks, and I don't have logs of it crashing, whereas I do have logs of dovecot crashing :) I'm confused as to what the last sentence says, do you mean that you were able to reproduce the crash?

If nothing big shows up, v1.0 should be out in a couple of weeks. * Renamed default_mail_env to mail_location. default_mail_env still works for backwards compatibility. * deliver: When sending rejects, don't include Content-Type in the rejected mail's headers. * LDAP changes: * If auth binds are used, bind back to the default dn before doing a search. Otherwise it could fail if a user gave an invalid password. * Initial binding at connect is now done asynchronously. * Use pass_attrs even with auth_bind=yes since it may contain useful non-password fields. + passdb checkpassword: Give TCPLOCALIP and TCPREMOTEIP and PROTO=TCP environments to the checkpassword binary so we're UCSPI (and vchkpw) compatible. - mbox handling was a bit broken in rc10 - Using Dovecot via inetd kept crashing dovecot master - deliver: Don't crash with -f "". Changed the default from envelope to be "MAILER-DAEMON". - INBOX wasn't shown with LSUB command if only prefixed namespaces were used. - passdb ldap: Reconnecting to LDAP server wasn't working with auth binds. - passdb sql: Non-plaintext authentication didn't work - MySQL passdb ignored all non-password checks, such as allow_nets - trash plugin was broken

[Dovecot] Deliver: command time exceed limit
by Dominique Feyer 12 Nov '06

12 Nov '06

We use Dovecot on a cluster (10'000 domains, 30'000 account) without any problem with pop/imap. We use Dovecot 1.0 RC10 Now we use virtual transport from postfix for mail delivery. We need the Dovecot LDA for sieve support. We test this solution on some domains with success. But if we change the configuration of all our domains, we have a lots of bounce with this error in postfix log: postfix/pipe[24573]: 4F6D7CF11: to=<info(a)XXXX.com>, relay=dovecot, delay=1200, status=bounced (Command time limit exceeded: "/usr/local/dovecot/libexec/dovecot/deliver") If I watch the deliver activity with ps/awk/watch, I see that if deliver duration time exceed some seconds, the deliver process stay in memory but do nothing. Here a strace output of this case: Process 349 attached - interrupt to quit gettimeofday({1161965973, 768478}, {0, 0}) = 0 poll( Strace output nothing before the SIGKILL from postfix (command time exceed 1200 second), the end of the strace: [{fd=5, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}, {fd=9, events=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL}], 2, 2147483647) = -1 EINTR (Interrupted system call) +++ killed by SIGKILL +++ I'm not sure is this problem has a relation with our deliver problem. But in the deliver log /var/log/dovecot/deliver, I have a lots of message: deliver(info(a)labomex.com): 2006.10.27 18:29:28 Error: file_dotlock_replace(/var/mail/labomex.com/mails/info/.dovecot.lda-dupes) failed: No such file or directory deliver(info(a)labomex.com): 2006.10.27 18:29:28 Error: rename(/var/mail/labomex.com/mails/info/.dovecot.lda-dupes.lock, /var/mail/labomex.com/mails/info/.dovecot.lda-dupes) failed: No such file or directory Our dovecot.conf (lda parts): protocol lda { postmaster_address = postmaster(a)clm.net4all.ch #hostname = mail_plugins = cmusieve mail_plugin_dir = /usr/local/dovecot/lib/dovecot/lda sendmail_path = /usr/sbin/sendmail auth_socket_path = /var/run/dovecot/auth-master log_timestamp = %Y.%m.%d %H:%M:%S%t log_path = /var/log/dovecot/deliver info_log_path = /var/log/dovecot/deliver.info } We use on UID/GID per domain so every account of a domain use the same UID/GID. The mail storage is on a Debian Sarge NFS server with 2.4.27-3-686-smp. Indexes are stored localy on each POP/IMAP/LDA server. I don't understand why we have this problem. If somebody can help us, thanks a lots. Dominique Feyer

[Dovecot] Writing to mail directory
by Gerard Seibert 12 Nov '06

12 Nov '06

FreeBSD 6.1 Dovecot 1.0.rc12 Using Dovecot as an LDA produces this error message: // START ERROR MESSAGE // deliver(gerard): Error:open(/var/mail/.temp.scorpio.seibercom.net.812.03034e3c3c1ab1c8) failed: Permission denied deliver(gerard): Error: file_lock_dotlock() failed with mbox file /var/mail/gerard: Permission denied // END ERROR MESSAGE// Actually, there are dozens of similar messages for all of my accounts. One example is enough to see what I am referring to. I am using Postfix for my mail-server. If I change the permissions on the directory to '1777' the error goes away and everything seems normal. The problem is that I should not have to do that and I do not understand what the problem is. Has anyone else experienced this phenomena and come up with a solution? Thanks! -- Gerard "Off list mail from *.gmail.com is rejected/deleted unseen. Don't waste your time."

[Dovecot] Using Substring Width with Mailhome Variables
by Matthew Fisch 12 Nov '06

12 Nov '06

Hello All, I am currently running Dovecot v1.0.rc13 from dovecot-1.0-0_31.rc13.fc5.at.i386.rpm on Linux HOST 2.6.17-1.2157_FC5 #1 Tue Jul 11 22:55:46 EDT 2006 i686 i686 i386 GNU/Linux. I am trying to install Dovecot in a large mail hosting environment and running into troubles. I have specified my mail home in dovecot.conf as follows: default_mail_env = maildir:/mnt/fileserver/maildir/%0.1d/%1.1d/%d/%n I've also tried among other variations: default_mail_env = maildir:/mnt/fileserver/maildir/%0d/%1.1d/%d/%n The expected behavior here, is to resolve this to: /mnt/fileserver/maildir/a/b/abc.com/user However, Dovecot seems to resolve this to: /mnt/raidzone01/maildir/abc.com/bc.com/abc.com/user/ It appears to me using 'width' with a substring does not work as is advertised on http://wiki.dovecot.org/Variables. This page does describe I need to be using 1.0-tests, what is 1.0-tests? I've also tried the default FC5 package: 1.0-0.beta8.2.fc5. Did I misunderstand the syntax? Am I using the wrong version? I won't be able to use dovecot without support for this feature as I am hosting many thousands of domains and know not how else to resolve them all. Thanks for all your time in advance, Matt Matthew Fisch Your-Site.com

[Dovecot] RFC 2822 - message-id
by Tom Allison 10 Nov '06

10 Nov '06

I was porting some email from one imap server location to another and ran into a feature of something. One of them writes message-id as 'Message-Id' and the other writes it as 'Message-ID'. Because of this, all the messages are forever different. All mail is delivered from postfix and will be in the future. But I'm asking which of these syntaxes is correct or if there is a right/wrong way of writing the headers? RFC2822 doesn't come right out and say it, but all the examples therein are "Message-ID". RFC 822 says they are all the same. Both?

[Dovecot] Qpopper migration?
by Steve Goodman (lists) 09 Nov '06

09 Nov '06

Hello, As this is my first post to the list, first and foremost I'd like to thank Timo for writing great software; we've successfully moved to Dovecot for over 10,000 users from UW-IMAP and get great performance. On our overloaded staff POP3/IMAP server, we are looking at replacing qpopper+uw-imapd with dovecot, as an interim before moving them to the main Unix mailstore. The system is primarily POP3, with a small number of heavy IMAP users causing the system grief. There are a large number of POP3 users who leave messages on the server. What I want to ensure doesn't happen is that they are forced to download them again. Do I need to add anything specific in the pop3_uidl_format or am I barking up the wrong tree? Kind Regards, Steve

[Dovecot] SSL-read error in logfile
by Egbert Jan van den Bussche 08 Nov '06

08 Nov '06

Now most things seem to work (rc12 on Mandriva 2007.0), I've been looking more thoroughly at the syslog file. I see a 'syscall failed' at the end of a normal timed poll from the client. I wonder what it means. Sorry for the layout, it is messed up by the cut and paste. I have created the selfsigned cert and key in the /etc/ssl/dovecot/[certs,private] directories.

[Dovecot] Quota without dovecot LDA
by Riccardo Bini 08 Nov '06

08 Nov '06

Hi all, I use dovecot with maildir quota plugin + qmail + vpopmail but not dovecot LDA. My dovecot configuration: default_mail_env=maildir:~/Maildir:INDEX=/var/cache/dovecot/indexes/%h/%u:CONTROL=/var/cache/dovecot/control/%h If CONTROL env is set the maildirsize file is stored in /var/cache/dovecot/control/ but I use vpopmail as LDA. It's possible to add a setting in dovecot.conf to specify if dovecot LDA is active?? This is my pseudo-patch: src/plugins/quota/quota-maildir.c static const char *maildirsize_get_path(struct mail_storage *storage) { if (lda_enable) { return t_strconcat(mail_storage_get_mailbox_control_dir(storage, ""), } else { bool is_file; return t_strconcat(mail_storage_get_mailbox_path(storage, "", &is_file), "/"MAILDIRSIZE_FILENAME, NULL); } } dovecot.conf: lda_enable = no Ciao Rick

[Dovecot] How to give system and virtual users their own mail_location?
by Egbert Jan 08 Nov '06

08 Nov '06

Hi all. Now hopefully as a new thread because I still have this question. Apologies to Geert and Timo for my misbehaviour...(repling to the list and changing the subject). I hace Dovecot rc12 working on Mandriva 2007.0 now for system accounts and virtual accounts both imap and imaps can be used. Th problem now is that I cannot use both types of user at the same time. The 'mail_location = ' strings are very different: Real system users have their Maildir in /home/%u/Maildir/ but virtual users have their maildir in /home/virtual/%d/%n/. How can tell dovecot to use the first for /etc/passwd clients and second for mysql authenticated clients? Just adding two private namespaces does not work. That is for ONE user having more mailbox locations, isn't it? Thanks for any hints! Egbert Jan (NL)

[Dovecot] L4 probes..
by Jorgen Lundman 08 Nov '06

08 Nov '06

Probably a special case here, but everytime the L4 probes the port, a line as added to the log. This gets a bit noisy. If a random IP connects, I'd want to see it, but maybe it would be nice to have the option to silence the log entry from certain hosts. For now I patch it locally, but without any .conf finesse. For example: Nov 8 10:55:24 corppop01 dovecot: [ID 107833 mail.info] pop3-login: Disconnected: rip=172.16.253.5, lip=172.16.253.128, TLS handshake Nov 8 10:58:00 corppop01 dovecot: [ID 107833 mail.info] pop3-login: Aborted login: rip=172.16.253.5, lip=172.16.253.128 -- Jorgen Lundman | <lundman(a)lundman.net> Unix Administrator | +81 (0)3 -5456-2687 ext 1017 (work) Shibuya-ku, Tokyo | +81 (0)90-5578-8500 (cell) Japan | +81 (0)3 -3375-1767 (home)

[Dovecot] deliver feature request (filter)
by Neal Becker 08 Nov '06

08 Nov '06

I'm using maildrop for delivery, because I want to filter through spamassassin before delivery. Maildrop makes that trivial. It seems deliver can pipe (one way) to a command, but what is needed is to pipe: deliver -> spamd -> deliver which is what the maildrop xfilter does.

[Dovecot] Corrupted index cache file dovecot.index.cache: invalid record size
by bofh list 07 Nov '06

Hi, Our dovecot setup consists of two hosts running dovecot-1.0.beta9 with Maildir/indices stored on NFS(noac,actimeo=0 used). I am seeing these messages at times - but no real problems on the client side. Is this something to worry about? dovecot: Oct 17 10:33:31 Error: IMAP(user): Corrupted index cache file mailstore/user/Maildir/.mail.incoming/dovecot.index.cache: invalid record size Thanks!

[Dovecot] RC10 errors
by Eric Rostetter 07 Nov '06

07 Nov '06

I just installed a limited test of RC10 last night. So far, all is great except for errors being logged for one user (out of about 150 users total). This one user has not yet complained or anything, but the log file has repeated entries of the following format for him (host and username changed to protect the guilty/innocent): Oct 24 06:13:02 mail dovecot: IMAP(username): file mbox-sync-rewrite.c: line 405 (mbox_sync_read_and_move): assertion failed: (need_space == (uoff_t)-mails[idx].space) Oct 24 06:13:02 mail1 dovecot: child 18235 (imap) killed with signal 6 I find it most interesting that only 1 out of 150+ users is getting this error... And again, no complaints from the user. Setup is: wu-imap mbox files in /var/spool/mail (exported via NFS, but local to the dovecot server). Mail in ~/mail/ (NFS mount, foreign to devecot server). Indexes in /var/dovecot/indexes (local to dovecot server with no NFS at all). -- Eric Rostetter The Department of Physics The University of Texas at Austin Go Longhorns!

[Dovecot] rc13 soon
by Timo Sirainen 07 Nov '06

07 Nov '06

I think I'll just start making new releases whenever I've fixed something important. You'll have a while to report more bugs and then I'll make rc13 release, maybe in about 5 hours or maybe tomorrow. I updated already the nightly snapshot if you want to test the upcoming rc13. Changes so far: + deliver: If we're executing as a normal system user, get the HOME environment from passwd if it's not set. This makes it possible to run deliver from .forward. - Older compilers caused LDAP authentication to crash - Dying LDAP connections weren't handled exactly correctly in rc11, although it seemed to work usually - Fixed crashes and memory leaks with AUTHENTICATE command - Fixed crashes and leaks with IMAP/POP3 proxying

[Dovecot] rc12 dovecot-auth core dump with ldap
by Chris Wakelin 07 Nov '06

07 Nov '06

Hi, I've got a core dump during initialisation when I use 1.0.rc12 and LDAP with authenticated binds in Solaris. It worked OK in 1.0.rc10. Here's the non-commented entries in dovecot-ldap.conf - some of which are probably redundant :) :- hosts = xxx.yyy.rdg.ac.uk auth_bind = yes auth_bind_userdn = "cn=%n,cn=users,dc=xxx,dc=yyy,dc=rdg,dc=ac,dc=uk" ldap_version = 3 base = "dc=xxx,dc=yyy,dc=rdg,dc=ac,dc=uk" deref = never scope = subtree user_filter = (&(objectClass=User)(sAMAccountName=%n)) pass_filter = (&(objectClass=User)(sAMAccountName=%n)) Strangely, it crashes in a different place when I don't define the scope, so I'm guessing it's something to do with reading parameters. backtrace with "scope = subtree" : #0 0x1ec94 in db_ldap_init ( config_path=0x5bc08 "/opt/RDGdovect/etc/dovecot-ldap.conf") at db-ldap.c:661 661 if (*conn->set.user_global_gid == '\0') (gdb) bt #0 0x1ec94 in db_ldap_init ( config_path=0x5bc08 "/opt/RDGdovect/etc/dovecot-ldap.conf") at db-ldap.c:661 #1 0x246e8 in passdb_ldap_preinit (auth_passdb=0x5bbe8, args=0x5bc08 "/opt/RDGdovect/etc/dovecot-ldap.conf") at passdb-ldap.c:486 #2 0x2328c in passdb_preinit (auth=0x5b838, driver=0xffbefec0 "ldap", args=0x0, id=332176) at passdb.c:169 #3 0x17648 in auth_preinit () at auth.c:45 #4 0x1ff0c in drop_privileges () at main.c:195 #5 0x2024c in main (argc=0, argv=0xffbefb54) at main.c:319 and with scope left commented out: #0 0xff0cf600 in strcasecmp () from /usr/lib/libc.so.1 (gdb) bt #0 0xff0cf600 in strcasecmp () from /usr/lib/libc.so.1 #1 0x1df58 in scope2str (str=0x0) at db-ldap.c:116 #2 0x1ec4c in db_ldap_init ( config_path=0x5bc08 "/opt/RDGdovect/etc/dovecot-ldap.conf") at db-ldap.c:648 #3 0x246e8 in passdb_ldap_preinit (auth_passdb=0x5bbe8, args=0x5bc08 "/opt/RDGdovect/etc/dovecot-ldap.conf") at passdb-ldap.c:486 #4 0x2328c in passdb_preinit (auth=0x5b838, driver=0xffbefec0 "ldap", args=0x0, id=332176) at passdb.c:169 #5 0x17648 in auth_preinit () at auth.c:45 #6 0x1ff0c in drop_privileges () at main.c:195 #7 0x2024c in main (argc=0, argv=0xffbefb54) at main.c:319 If I don't define "deref" then I get an error in the dovecot log (but no crash) :- dovecot: Nov 07 12:36:45 Error: auth(default): LDAP: Unknown deref option 'subtree' I'll keep digging and see if I can find the cause, but has anybody else seen this?

[Dovecot] suspected bug in dovecot-ldap setup?
by Pedro Venda 07 Nov '06

07 Nov '06

Hi everyone, [first post: long and boring. beware!] I've been working on a virtual multidomain MX server with pop3 access. Accounting for users/domains is done via OpenLDAP with the Jamm[1] schema and dovecot is 1.0rc10 (dovecot-1.0-0_27.rc10.el4.at fetched as RPM from atrpms.net for CentOS 4.4). I intended to have authenticated binds but there was a problem with the user_filter directive being ignored: user_filter = (&(objectClass=JammMailAccount)(mail=%n@%d)(accountActive=TRUE) (delete=FALSE)) dovecot: Oct 26 16:20:58 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=::ffff:192.168.0.5 rip=::ffff:192.168.0.69 resp=<hidden> dovecot: Oct 26 16:20:58 Info: auth(default): ldap(dave@info.test,::ffff:192.168.0.69): bind search: base=o=hosting,dc=example,dc=com scope=subtree filter= **(&(objectClass=posixAccount(uid=dave(a)info.test))** dovecot: Oct 26 16:20:58 Info: auth(default): ldap(dave@info.test,::ffff:192.168.0.69): unknown user dovecot: Oct 26 16:20:59 Info: auth(default): client out: FAIL 1 user=dave(a)info.test dovecot: Oct 26 16:20:59 Info: imap-login: Disconnected: user=<dave(a)info.test>, method=PLAIN, rip=::ffff:192.168.0.69, lip=::ffff:192.168.0.5, TLS (nevermind the data, it's test only) As you can see from the info file, the search filter used was being (&(objectClass=posixAccount(uid=dave(a)info.test)) and not (&(objectClass=JammMailAccount)(mail=dave(a)info.test)(accountActive=TRUE) (delete=FALSE)). I sorted this out by trying to enable auth_bind_userdn: auth_bind_userdn = mail=%n@%d,jvd=%d,o=hosting,dc=example,dc=com Now, the login worked well and the debug info is as follows: dovecot: Oct 27 12:01:48 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip=::ffff:192.168.0.5 rip=::ffff:192.168.0.69 resp=AGRhdmVAaW5mb y50ZXN0AFRlbXAuMTIz dovecot: Oct 27 12:01:48 Info: auth(default): client out: OK 1 user=dave(a)info.test dovecot: Oct 27 12:01:48 Info: auth(default): master in: REQUEST 1 10634 1 dovecot: Oct 27 12:01:48 Info: auth(default): ldap(dave@info.test,::ffff:192.168.0.69): base=o=hosting,dc=example,dc=com scope=subtree filter=(&(objectClass=JammMailAccount)(mail=dave(a)info.test) (accountActive=TRUE)(delete=FALSE)) fields=mailbox dovecot: Oct 27 12:01:48 Info: auth(default): master out: USER 1 dave(a)info.test mail=info.test/dave/ uid=5000 gid=5000 (nevermind the debug data, passwords, etc. it's test only) In this case, the search filter is ok: (&(objectClass=JammMailAccount)(mail=dave(a)info.test)(accountActive=TRUE) (delete=FALSE)) So aparently, the auth_bind_userdn directive that supposedly adds a performance gain by sparing one bind request, seems to interfere with the user_filter directive. I suspect this might be a bug, so here's my report. Is this a new issue? Thanks for surviving this far through this post, Best regards, Pedro Venda.

[Dovecot] Store outgoing mail in users mailbox
by Mark Ruys 07 Nov '06

07 Nov '06

This might be a MTA question, but because I use Dovecot as an LDA, maybe some can help me here. Our users would like that outgoing mail is automatically saved in some folder, say Sent. We use Postfix with virtual domains, Maildir and Dovecot+Sieve as LDA. Outgoing mail is relayed by our imap-server (with authentification of course, no open relay). Most people seem to advice Postfix sender_bcc_maps and Dovecot's deliver with the -m argument. But I can't get it work. I tried: In master.cf: dovecot-archive unix - n n - - pipe flags=DRhu user=mailowner:mailowner argv=/usr/libexec/dovecot/deliver -d ${recipient} -m Sent In main.cf: sender_bcc_maps = hash:/etc/postfix/sender_bcc_map In sender_bcc_map: tester(a)ruijs.cc dovecot-archive: But that doesn't work. It looks like "dovecot-archive:" should be a real email address, not a transport (this give an idea of my Postfix knowledge ;). Then I tried: In sender_bcc_map: tester(a)ruijs.cc tester+archive(a)ruijs.cc But I don't think Dovecot's LDA supports plus addressing. So my question is, has anyone here done a similar thing in a similar setting. If so, how did you configure it.

[Dovecot] Upgrade from RC7 to RC10 didn't go too well...
by Ivo Truxa 06 Nov '06

06 Nov '06

I have the same problem after upgrading to RC10. Did you find a solution? Should I update to RC11 or rather downgrade back to an earlier version? Thanks, Ivo Truxa >>>>>>> original message >>>>>>> Hi, On the weekend I tried to upgrade from RC7 to RC10. Clearly, I have to change some things before I can do this. What does it take to get to RC10? As is, my mail client got an error trying to list messages in /INBOX (via IMAP) and the mail.err log shows the following messages: Oct 29 10:27:32 siona dovecot: IMAP(archangel): open(/var/mail/archangel/inbox, O_CREAT) failed: Not a directory Oct 29 10:27:32 siona dovecot: IMAP(archangel): mkdir_parents(/var/mail/archangel/.imap/INBOX) failed: Not a directory Oct 29 10:27:32 siona dovecot: IMAP(archangel): open() failed with subscription file /var/mail/archangel/.subscriptions: Not a directory My dovecot.conf includes default_mail_env = mbox:/var/mail/%u And other then enabling SSL, I've got a pretty vanilla configuration (e.g. nothing in the IMAP section at all, no odd namespaces...) /var/mail/archangel is an mbox file, why is dovecot trying to open files under there? I know at least part of the discussion has happened on the list before so I'm sorry for duplicating other questions. My TODO is about ten km long so I hope someone can at least give me a couple good pointers. Thanks in advance! -- Dominic Lepiane The IRMACS Centre

[Dovecot] v1.0 plans, rc11 tomorrow
by Timo Sirainen 06 Nov '06

06 Nov '06

As you can probably guess from my today's burst of activity, I'm no longer extremely busy. Actually it looks like for the next 3-4 weeks I don't have anything especially time consuming to do. So it's time to get Dovecot v1.0 released :) I've now read all the mails from this list again, and it looks like pretty much the only problems with rc10 was the mbox assert crash, which is now fixed. My TODO contains: v1.0 blocker: - inetd logins are broken? I should look more into this.. I only remembered this just now while writing this mail. New non-v1.0 blockers: - trash plugin is apparently broken? - mbox_min_index_size != 0 causes Invalid new transaction log sequence (4 >= 4) The old preferrably-fixed-for-v1.0 items are: - ldap auth is leaking memory? maybe not, maybe it's something else. - master leaks log fds with kqueue. I don't have a machine to test this on. Could someone give me an account in some BSD system for a while to test this? Anyway, I'll most likely release rc11 tomorrow, but it would be nice if you tested today's CVS snapshot already to see if I accidentally broke something. :) http://dovecot.org/nightly/dovecot-latest.tar.gz Oh and one thing that I wanted for Dovecot v1.0 was nice documentation. I think the current wiki is a bit chaotic. I started http://wiki.dovecot.org/NewIndex a long time ago. Maybe I should finish it finally and put it as the new main index..

[Dovecot] Auto-expire messages in a folder
by Mike Cisar 05 Nov '06

05 Nov '06

I have a Fedora 5 server running Dovecot (currently 1.0 rc10). The spam filter (amavis) automatically tags email (using plussed addressing) such that messages flagged as spam are sorted into a "spambox" folder by procmail. Seemed like a good idea at the time, but because of some legacy issues with filesystem quota also being in place, combined with most users connecting with POP3 rather than IMAP... spam doesn't stay in their inbox, they don't check their spambox and they are very quickly over quota. What I would like to do is stick with the "spambox" folder idea, but have any messages in that folder which are older than a certain number of days deleted automatically. Could this be done by Dovecot? If so how would dovecot know to visit all the user's mailboxes to do it... or would it only be able to do so when a user logged in via IMAP (as opposed to POP3)? If not, is anyone aware of a script that I could run in nightly maintenance to do a cleanup pass on all the mailboxes? I know there are any number of ways that this could be accomplished but I would like to do it as much within my existing framework as possible... sendmail/procmail/amavis on the delivery side, dovecot in the middle, horde/imp for webmail and whatever email client the end users have (likely Outlook/Outlook Express for the most part)... all pretty generic, standard mailbox formats... nothing fancy like data stored in mySQL or anything like that. As everyone encounters, the more parts you change, the more other parts you have to fix to be compatible with the changes :-) Obviously I would like the solution to also be as feature rich as I can at the same time (might as well wish for it all right :-). Maybe for the sake of the POP3 folks it would also be nice to generate a once-daily email with the names, subjects of the messages in the folder saying "here's what is in your spam folder, please log in to webmail to manage your spam" (and in a perfect world some sort of link to click on which could move the message from the spambox back into the inbox). Does anyone have any solutions they can share that run within a similar framework to what I have set up? The thing that I need in the immediate term is to purge the spam folder automatically, the mid-term goal is to evolve that into a sort of spam-processing center/solution for the users. Thanks for any suggestions! Cheers, >>>>> Mike <<<<<

[Dovecot] ~/.maildir preferable to %h/Maildir and ~/Maildir?
by Jeff Kowalczyk 05 Nov '06

05 Nov '06

I have a recently deployed dovecot server and am readying another. Upon updating to rc12, I note the following change in the default dovecot.conf file: -default_mail_env = mbox:/var/spool/mail/%u:INDEX=/var/dovecot/%u +mail_location = maildir:~/.maildir Integrating this change to my local dovecot.conf: # formerly used default_mail_env = maildir:%h/Maildir # dovecot default mail_location = maildir:~/.maildir mail_location = maildir:~/Maildir With unix users of the form: myuser:x:505:100:My User:/home/myuser:/sbin/nologin each having ~/Maildir, should I: 1) use the ~/.maildir form over ~/Maildir. 2) use the ~ instead of %h 3) do anything for dovecot's benefit (reindex, etc.) besides a per-user 'mv ~/Maildir ~/.maildir' if 1). I came straight from an ancient sendmail mbox setup to dovecot, so I want to do things the best-pracitce IMAP/dovecot way. Thanks.

[Dovecot] Sending email using IMAP
by Marc Perkel 05 Nov '06

05 Nov '06

This is something for after the 1.0 release but I think it's important and I'm going to try to figure out how to make it happen. I'd like to see some way to pass outgoing email from Thunderbird back to dovecot through some new command that we would have to make up. Email would be sent back over the IMAP connection and when Dovecot gets it dovecot would hand it off to an SMTP server that would deliver it. If a crude experimental spec can be written I'll try to find someone on the Thunderbird side to write some sort of module to talk to it. The reason for this is that I think that the elimination of SMTP from the client is a big step to control spam. The idea being that if IMAP can transfer outgoing mail the SMTP wouldn't be necessary for clients and we can block port 25 on windows machines and viruses can't send email. And the virus wouldn't have access to the IMAP password so viruses can't authenticate to send mail. So - the key question is - what would it take to create an outgoing spec for sending email over IMAP? Like to see something clean and simple.

[Dovecot] MySQL Configuration
by Gerard Seibert 04 Nov '06

04 Nov '06

Dovecot 1.0.rc10 FreeBSD 6.1 This is probably a dumb question; however, I have never let a little thing like that bother me in the past. In the 'dovecot.conf' file there are the follow two sections: # SQL database passdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /usr/local/etc/dovecot-sql.conf } userdb sql { # Path for SQL configuration file, see doc/dovecot-sql.conf for example args = /usr/local/etc/dovecot-sql.conf } I keep the 'users' and their respective 'passwords' in the same MySQL database. I am not sure why I wouldn't. Therefore, would it not make more sense to have just one MySQL configuration line in the 'dovecot.conf' file rather than two, or am I missing something here? -- Gerard Seibert gerard(a)seibercom.net Laws are like sausages.

[Dovecot] auth-req-handler.c adds spurious tab
by Chris Laif 04 Nov '06

04 Nov '06

If the auth backend (postgresql in my case) returns extra fields, and all of these extra_fields begin with 'userdb_', the auth_callback functions adds an unwanted extra tab at the end of the response: auth(default): client out: OK^I8^Iuser=foo@bar^I This extra tab at the end confuses exim's dovecot-auth handler (the exim-dovecot auth handler does not correctly count the number of returned fields then (side note: the code on exim's side should probably be cleaned up as well)). A quick fix is attached below.

I made a copy of the mbox file, and find that it's over a megabyte long. Checking the postfix maillog I find that only three messages arrived for that user in the hour preceding the start of this behavior (all SPAM). No other users are affected, and I can't see anything obviously wrong in the mbox file. Could a bad message cause this?

[Dovecot] Server-side mail archiving - possible dovecot lda feature?
by Charles Marcus 03 Nov '06

03 Nov '06

Hi Timo, I have a question on the feasibility of adding the capability directly in dovecot LDA (or maybe this wouldn't be the correct place?) to provide a server-side mail archiving feature. What I'd like is a simple way to define a maildir, ie: vmail/archive/$user/Inbox and vmail/archive/$user/Inbox.Sent And then have the dovecot LDA deliver a copy of all mail (incoming and outgoing) to this archive folder. Is the dovecot LDA the best place for this to go? Or would an entirely new plug-in be more appropriate? My boss may be willing to pay to have this capability added. I have investigated other third party solutions, but I would prefer something that is tightly integrated with dovecot. I look forward to your response... -- Best regards, Charles

Hi all, I have instaled dovecot 1.0.rc10, and my configuration works fine if I get the mail with Evolution mail client, bu if I try to use outlook to get mails the authentication fail and I can't pass through the logon window. The maillog appear this message: dovecot: pop3-login: Disconnected: rip=192.168.0.22, lip=192.168.0.1 My dovecot configuration is: protocols = pop3 ssl_disable = yes mail_extra_groups = mail protocol imap { } protocol pop3 { pop3_uidl_format = %v.%u } protocol lda { postmaster_address = postmaster(a)example.com } auth_username_translation = "@." auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } dict { } plugin { } any idea to solve. thanks Paul

[Dovecot] any idea why the mail downloading is slow?
by LeVA 03 Nov '06

03 Nov '06

Hi! I'm using rc10, but had this problem with previous releases too. Not sure if this is a dovecot problem, but I can not think of anything else. The mail downloading with pop3 is ~very slow, approx. 20 Kbyte / sec. no matter how many mails I've got in my mailbox, or how big are the mails. My ISP provides me a dedicated 100mbit line, and everything else works as fast as expected eg. http, ftp, scp... The OS is OpenBSD 3.9-stable and the system is not under heavy load at all. I've tried to turn off TLS but there was no change. Is the pop3 protocol this slow by design or there is something wrong with my setup? Thanks! Daniel -- LeVA

[Dovecot] CRAM-MD5 auth broken with postgresql passdb?
by Chris Laif 03 Nov '06

03 Nov '06

I'm currently experiencing a problem which has already been described by Jonathan in http://www.dovecot.org/list/dovecot/2006-August/015501.html If I use CRAM-MD5 auth with passwd-file as a backend (Thunderbird client) everything works fine (MD5-hashes have been shortened for readability): dovecot: auth(default): password(bob(a)foo.bar,10.0.0.123): Credentials: f12c884ba3cc82.. dovecot: imap-login: Login: user=<bob(a)foo.bar>, method=CRAM-MD5, rip=10.0.0.123, lip=10.0.0.234 My passwd file contains a line like this: bob@foo.bar:{HMAC-MD5}f12c884ba3cc82.. If I change to postgresql-based passdb, PLAIN auth works (!) and CRAM-MD5 does not work: dovecot: auth(default): sql(bob(a)foo.bar,10.0.0.123): query: SELECT 'bob(a)foo.bar' AS user, '{HMAC-MD5}f12c884ba3cc82..' AS password dovecot: auth(default): password(bob(a)foo.bar,10.0.0.123): Credentials: dovecot: auth(default): cram-md5(bob(a)foo.bar,10.0.0.123): password mismatch Please note the ultra-simple SELECT-statement (I've tried other combinations as well - no success). sql.conf setting is "default_pass_scheme = HMAC-MD5". Dovecot version 1.0.rc10. In the postgresql-based example the "Credentials:" variable is empty. I wonder if this is a bug in dovecot. Please let me know if you need any further information to resolve this issue. Thanks, Chris (As a side not I still do not understand how CRAM-MD5 auth is able to work without a plain text password, but that's another story. If it works with an HMAC-MD5 hash in a passwd-file backend it should work with the postgresql-db backend as well.)

Hello, I found this thread: http://www.dovecot.org/list/dovecot/2006- September/015955.html and have successfully compiled and installed cmusieve plugin. How does one test to make sure its being loaded? It's not parsing my sieve files in the users homes and I'd like to first check if the plugin is being loaded, since I am getting no errors about it. Thanks

[Dovecot] Postfix + Dovecot LDA Problem
by Steven F Siirila 03 Nov '06

03 Nov '06

I am having a problem setting up a server to handle e-mail in a way in which it had always done traditionally, but with Postfix+Dovecot LDA. Here's a rundown... Solaris 9 Postfix 2.3.3 Dovecot 1.0.rc10 Postfix non-defaults (postconf -n): alias_maps = dbm:/etc/mail/aliases command_directory = /opt/postfix/sbin config_directory = /etc/opt/postfix daemon_directory = /opt/postfix/libexec debug_peer_level = 2 html_directory = no inet_interfaces = $myhostname mail_owner = postfix mailbox_command = /opt/dovecot/libexec/dovecot/deliver -f "$SENDER" mailq_path = /opt/postfix/bin/mailq manpage_directory = /opt/postfix/man masquerade_domains = tc.umn.edu masquerade_exceptions = root mydestination = $myhostname mynetworks = 127.0.0.0/8, ... (omitted) myorigin = $mydomain newaliases_path = /opt/postfix/bin/newaliases queue_directory = /var/spool/postfix readme_directory = no relayhost = [omitted.tc.umn.edu] sample_directory = /etc/opt/postfix sendmail_path = /opt/postfix/sbin/sendmail setgid_group = postdrop smtpd_client_restrictions = permit_mynetworks, reject unknown_local_recipient_reject_code = 550 This works just like our old MTA, with one exception: sending e-mail to addresses within our domain (@tc.umn.edu) requires us to specify the @tc.umn.edu -- otherwise it is rejected with a message like alias(a)host.tc.umn.edu does not exist. I want such messages to be relayed to the relayhost. When I set mydestination to null, and luser_relay = $user@$domain the message goes into a black hole (I never get the message, nor do I get an NDN.) I am posting this to both the Dovecot and Postfix lists since I'm not sure where the fault lies, configuration- or software-wise. Thanks in advance for any helpful tips. -- Steven F.

Our server is an CentOS4.4 box and we use the atrpms built RPMs for installing dovecot. I am wanting to use the sieve plug-in so I've followed the dovecot wiki instructions, downloaded the files from CVS, but I'm not sure what configure options to use. When I try without any options I get: dovecot-config not found from /usr/src/dovecot-sieve, use --with-dovecot=PATH to give path to compiled Dovecot sources I tried using "./configure --with-dovecot=/usr/libexec/dovecot" but get the same problem.

[Dovecot] making dovecot and exim write to one log
by Zbigniew Szalbot 02 Nov '06

02 Nov '06

Hello, I am looking for some advice. I am trying to force dovecot to run to the same log as exim does. In dovecot.conf I put the exim log path /var/log/exim/mainlog. I restarted dovecot and the process worked fine. However at midnight exim log file is rotated and since then dovecot stops logging to this log. In syslog.conf I put: mail.* /var/log/exim/mainlog And in newsyslog.conf I have: /var/log/exim/mainlog mailnull:mail 640 60 * @T00 Z I used to have an N flag next to Z but after reading the man I realized that its job is not to inform other processes about log creation. My qeustion is how do I set up things that dovecot and exim happily write to one log without having to restart dovecot at midnight? I am fairly new to FreeBSD which I use so I beg your patience with me. Thanks! -- Zbigniew Szalbot

Re: [Dovecot] deliver + quota failure
by Mark Ruijs 02 Nov '06

02 Nov '06

I investigated the deliver with quota's bug a little more (rc10, mysql, virtual domains, maildir). My log files reads: deliver(test(a)ruijs.cc): Info: msgid=<000f01c6fac1$bd4e8670$8801a8c0@Moskou>: save failed to INBOX deliver(test(a)ruijs.cc): Info: sieve runtime error: Keep: Generic Error deliver(test(a)ruijs.cc): Info: msgid=<000f01c6fac1$bd4e8670$8801a8c0@Moskou>: save failed to INBOX deliver(test(a)ruijs.cc): Error: open(ruijs.cc/test//.temp.in2sports2.vianetworks.nl.13210.72d247ac698d0019) failed: No such file or directory deliver(mark(a)ruijs.cc): Info: msgid=<dovecot-1162066721-407295-0(a)in2sports2.vianetworks.nl>: saved mail to Junk Dovecot tries to deliver, but notices quota exceeded. I don't think Sieve is playing a role here - I added Sieve before I encountered the problem. Two problems: 1) The .dovecot.lda-dupes can't be written (that's what the open...failed notice is about). 2) The Quota Exceed mail seem to contain mal-formed headers (that's why it the notice-mail ends in my junk-folder). Digging into deliver.c, I noticed that auth_client_put_user_env() changes the HOME environment from /var/mail (which is ok), to ruijs.cc/test/ (which is the maildir, relative to /var/mail). And then fopen fails (see the trace below). So I think that the code auth_socket = getenv("AUTH_SOCKET_PATH"); if (auth_socket == NULL) auth_socket = DEFAULT_AUTH_SOCKET_PATH; ret = auth_client_put_user_env(ioloop, auth_socket, destination, process_euid); if (ret != 0) return ret; home = getenv("HOME"); if (home != NULL) { /* If possible chdir to home directory so core file could be written. If it fails, don't worry. */ (void)chdir(home); is the key. Should the chdir be done *before* the call to auth_client_put_user_env()? I'm not familiar with the internal workings of the Dovecot LDA, so I won't suggest a proper fix. Who will. As for the mal-formed headers, I'll take a look at it later.

[Dovecot] INBOX un-subscribable (is that a word?)
by Jim Horner 02 Nov '06

02 Nov '06

I am trying to get open-xchange installed and working (which after two days might be futile). In doing this I noticed that no email client can subscribe to INBOX. I'm using rc10 and my namespaces are the following. 99% of the email clients ignore the inability to subscribe to INBOX and display all the folders underneath anyway which is why I've never noticed this issue... however, open-xchange is not in that camp and only displays messages in INBOX. All folders are in the subscriptions file including INBOX but all email clients always list INBOX as not subscribed to. COMPANY are ROOTMAIL are share folders with ACLs in /etc/dovecot/acl and those top folders are not subscribable either. namespace public { separator = . prefix = COMPANY. location = maildir:/home/services/mail/arinbe.com/arinbe/Maildir:CONTROL=%h/shared-set… hidden = no inbox = no } namespace public { separator = . prefix = ROOTMAIL. location = maildir:/home/services/mail/arinbe.com/rootmail/Maildir:CONTROL=%h/shared-s… hidden = no inbox = no } # default namespace namespace private { separator = . inbox = yes hidden = no prefix = INBOX. }

Hello all, I recently switched to dovecot on my FC4 server from UW-IMAP on my Mac OS X 10.3 machine and I was able to get my inbox and my trash box to be seen without any issues but all of my other mailboxes don't seem to show up. My mail directory is ~/mail and that is where I placed all of my mailboxes that I moved from my mac, but when I log into my new server using SSL/IMAP, only my trash and my inbox show up. My other mailboxes don't show up at all. Can anyone tell me how I can get my other mailboxes to show? As far as I know these mailboxes are standard unix mailbox files. Thanks

[Dovecot] another suggestion

On our solaris systems we quite often sees dovecot coredump on exit when trying to free a null buffer. After including if (array->buffer == NULL) return; in array_free() in array.h these coredums have been avoided. hmk

[Dovecot] BUG in RC10 deliver using mbox format
by Steven F Siirila 02 Nov '06

02 Nov '06

After recently adding the -f parameter to the call to the deliver command which is called by Postfix, I found that e-mail with a null return path (MAIL FROM:<>) was causing Dovecot deliver to SEGFAULT. I verified this by making this patch to deliver.c (notice I fixed a typo here, too): *** deliver.c.orig Fri Oct 13 07:32:28 2006 --- deliver.c Fri Oct 27 21:26:08 2006 *************** *** 446,454 **** i++; if (i == argc) { i_fatal_status(EX_USAGE, ! "Missing envleope argument"); } ! envelope_sender = argv[i]; } else { print_help(); i_fatal_status(EX_USAGE, --- 446,455 ---- i++; if (i == argc) { i_fatal_status(EX_USAGE, ! "Missing envelope argument"); } ! if (*argv[i]) ! envelope_sender = argv[i]; } else { print_help(); i_fatal_status(EX_USAGE, While this fixed my SEGFAULT, it still leaves the "From_" line with the default "dovecot.deliver" as the return path, something I don't want. It should be "MAILER-DAEMON" or some-such just like all the other LDAs in the case of a NULL return path. Perhaps there needs to be a new parameter so one can specify what a NULL return path should be converted to when it is encountered... Also, note that the "Usage" message in deliver.c does not include the relatively new -f option either, so that should have been part of my above patch as well. -- Steven F.

[Dovecot] quota with sendmail and dovecot
by Antonio Casado Rodríguez 02 Nov '06

I have a problem with dovecot and quotas I don't want quota in INBOX with sendmail (mbox), it's work ok. Sendmail can put the new messages in INBOX although exceed the quota limit. I have two namespace in dovecot: namespace private { separator = / inbox = yes prefix = "#mbox/" location = mbox:/Public/Maildir/%n_mbox_indexes:INBOX=/var/mail/%n } namespace private { separator = / prefix = "" location = maildir:/Public/Maildir/%n } I have this quota: plugin { quota = maildir:storage=10240 } It's work ok, i have 10 MB in INBOX and i have 10 MB in maildir. My clients are Mozilla Thunderbird My problem: when Sendmail put one new message in INBOX, Thunderbird see it, but the quota don't change. I think that when dovecot do a full sync it must update the quota.
