[Dovecot] SASL bind for LDAP
by Geert Jansen 13 May '06

13 May '06

Hi, would it be possible to add support for SASL binds to dovecot's LDAP userdb/passdb? This would be a nice feature as it would allow the use of SASL EXTERNAL binds to a local LDAP server, thereby removing the need for storing clear-text passwords in configuration files. Regards, Geert

[Dovecot] LDA Sieve feature request
by Luca Corti 12 May '06

12 May '06

Hello, In http://wiki.dovecot.org/LDA I read # If there is no user-specific Sieve-script, global Sieve script is # executed if set. #global_script_path = so you can set global_script_path and override it using a per user script. It would be nice if the per user scripts could be optionally run after (or before maybe?) the global script. Another nice thing would be per-virtualdomain sieve scripts, but I think this is much more difficult. What do you think? -- Luca Corti PGP Key ID 1F38C091 BOFH excuse of the moment: The Borg tried to assimilate your system. Resistance is futile.

[Dovecot] 1.0.beta8 released
by Timo Sirainen 12 May '06

12 May '06

Next release will probably be called 1.0.rc1. People just don't seem to like the beta name in the version number. :) Also I think we're nearing the final v1.0. * Fixed a security hole with mbox: "1 LIST .. *" command could list all directories and files under the mbox root directory, so if your mails were stored in eg. /var/mail/%u/ directory, the command would list everything under /var/mail. + Unless nfs_check=no or mmap_disable=yes, check for the first login if the user's index directory exists in NFS mount. If so, refuse to run. This is done only on first login to avoid constant extra overhead. + If we have plugins set and imap_capability unset, figure out the IMAP capabilities automatically by running imap binary at startup. The generated capability list isn't updated until Dovecot is restarted completely, so if you add or remove IMAP plugins you should restart. If you have problems related to this, set imap_capabilities setting manually to work around it. + Added auth_username_format setting - pop3_lock_session setting wasn't really working - Lots of fixes related to quota handling. It's still not working perfectly though. - Lots of index handling fixes, especially with mmap_disable=yes - Maildir: saving mails could have sometimes caused "Append with UID n, but next_uid = m" errors - flock() locking never timeouted because ignoring SIGALRM caused the system call just to be restarted when SIGALRM occurred (probably not with all OSes though?) - kqueue: Fixed "Unrecognized event".

[Dovecot] userdb prefetch not working with dovecot LDA?

Hello, I've configured MySQL authentication as follows. -- divecot-sql.conf -- driver = mysql connect = host=localhost dbname=postfix user=myuser password=mypass default_pass_scheme = PLAIN password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT CONCAT('/var/vmail/', maildir, 'Maildir') AS home, '1234' AS uid, '1234' AS gid FROM mailbox WHERE username = '%u' -- dovecot.conf -- passdb sql { args = /usr/local/etc/dovecot-sql.conf } userdb sql { args = /usr/local/etc/dovecot-sql.conf } And both access (IMAP) and delivery (LDA) work correctly.

[Dovecot] dovecot-lda and sieve filtering (SMTP is Postfix)
by Der Olli 12 May '06

12 May '06

Hello list. I've got a working Dovecot with Postfix and MySQL-support but everything from the capabilities of sieve isn't working except one thing: Sorting emails to folders works fine. But no vacation, no reject, no redirect. I don't get any errors in the logs. Verbose logging is enabled. I compiled both from newest cvs-sources but also tried older combinations (nightly snapshots). Always the same result and there's no .dovecot.sieve.err so script is okay. If it is not, .dovecot.sieve.err will be generated. I've tested this :) Anyone here who has a working sieve implementation with dovecot-lda? Where do I have to search? Is it a configuration problem? Where can I configure which sending mechanism dovecot-lda should use? Is it a local sendmail binary? Where does dovecot-lda search for it. Is it a SMTP-server? So there's one on port 25 at the local machine. Greetz, Olli

[Dovecot] comment on dovecot documentation on PAM
by president＠irithm.com 12 May '06

12 May '06

Dear Dovecote devotees, I have been going through dovecot configuration for the first time. I am not an experienced systems administrator so I had to do a left turn to read up about PAM while doing all the configuration for my new webmail service. I found that the writing in the dovecot documentation about PAM to be rather misleading in at least one aspect. The documentation I am specifically referring to is at http://wiki.dovecot.org/Authentication?highlight=%28authentication%29 and in the comments found in the dovecot.conf file. In this documentation PAM is referred to as a password database. It appears that is not correct, rather PAM is something that uses a password database. Since the default for "auth_passdb" given in dovecot.conf was "pam" I spent sometime trying to find a pam password database. I eventually found out at an independent website that what pam uses is either /etc/passwd or /etc/shadow or /etc/samba/smbpasswd. It was a relief to find out pam uses one of these, since my system has one of them (/etc/shadow), but I was looking to find something quite different for pam since /etc/shadow is one of the listed alternative values for "auth_passdb". I would have been spared a somewhat lengthy search to find out this information if the documentation was written rather more clearly. So, to help others, I suggest changing the following lines in dovecot.conf # Where password database is kept: # passwd: /etc/passwd or similiar, using getpwnam() # shadow: /etc/shadow or similiar, using getspnam() # pam [<service> | *]: PAM authentication to: # Where password database is kept: # passwd: /etc/passwd or similiar, using getpwnam() # shadow: /etc/shadow or similiar, using getspnam() # pam [<service> | *]: /etc/shadow or similiar, using PAM authentication Updating the documentation in http://wiki.dovecot.org/Authentication?highlight=%28authentication%29 to include a phrase that mentions that PAM authentication works from one of the standard password databases (i.e. /etc/passwd, /etc/shadow or /etc/samba/smbpasswd) would also be helpful. yours sincerely, Rolf

Hi all, Another user posted the same thing a few months back... after contacting them, they said they never got it working. I'm unable to get Pocket Outlook, or FlexMail 2006 working on Dovecot 0.99.13. According to the logs it connects just fine. With Pocket Outlook I'll see the headers for a few seconds, and then it clears and shows nothing. With FlexMail, which is supposed to have fantastic IMAP support (and has tons of options), I just see an empty inbox. Any ideas?? .josh

[Dovecot] mandatory client certificates and crl check in ssl-proxy-openssl.c
by HenkJan Wolthuis 11 May '06

11 May '06

hello, I made a modification to ssl-proxy-openssl.c (patch attached) zo that it a) disconnects when no client certificate is presented b) checks the client certificate against the crl for our root cert. (so you can't use a revoked client cert.) c) returns the CommonName from the client cert. in ssl_proxy_get_peer_name (this way it's easier to use dovecot as imap-proxy with a passwd-like userdb, ssl_require_client_cert and ssl_username_from_cert, it "binds" the emailuser to the clientcertificate, a clientcert. can access only the account from the userdb) in order to use it, the CAfile must be a file which contains the CAcertificate (pem format) followed by the CRL (also in pem format). (servercert and the clientcerts are signed with a self-signed rootcert) there are some issues with the patch: a) it needs openssl > 0.9.7 for the CRL checking b) ssl_verify_client_cert now returns 0 in case of an invalid cert. was there a reason why it always returned 1? c) i'm not too happy with the commonname extraction code, is it secure?? d) i've no experience with programming openssl or dovecot e) i haven't programmed in C for at least 8 years...... does anyone here have more issues, corrections, comments on the patch? can/should this functionality be implemented in dovecot?

[Dovecot] "QUOTA" CAPABILITY keyword advertised incorrectly?
by Mike Brudenell 11 May '06

11 May '06

Greetings - I'm having a frustrating time with mail clients not picking up Dovecot's QUOTA extension to IMAP. The problem is that the QUOTA keyword isn't advertised in Dovecot's response to a CAPABILITY enquiry until *after* the user has authenticated. Unfortunately I've yet to find a mail client that issues a CAPABILITY request after authenticating. Instead all do so upon initial connection to the IMAP server (and, correctly, again after subsequently initiating a STARTTLS session but before authentication). Not re-querying the CAPABILITY after authentication is correct according to the IMAP spec in RFC2060, which says: 6.1.1. CAPABILITY Command Arguments: none Responses: REQUIRED untagged response: CAPABILITY Result: OK - capability completed BAD - command unknown or arguments invalid The CAPABILITY command requests a listing of capabilities that the server supports. The server MUST send a single untagged CAPABILITY response with "IMAP4rev1" as one of the listed capabilities before the (tagged) OK response. This listing of capabilities is not dependent upon connection state or user. It is therefore not necessary to issue a CAPABILITY command more than once in a connection. In particular the last two sentences are relevant. (At present Dovecot is only advertising availability of the QUOTA extension *after* authentication, and hence *is* dependent on the user.) Ths means that at present Dovecot's provision of the QUOTA extension isn't actually getting used by popular mail clients such as Thunderbird.

[Dovecot] IMAP threading - the THREAD command
by Jan Kundrát 11 May '06

11 May '06

Hi folks, there's an extension [1] to IMAP specifying the THREAD command to return list of message sequence numbers grouped to indicate the threading of them. That draft currently defines two algorithms, one of them based solely on Subjects (which is rather dumb) and the second one, combining Subjects with In-Reply-To (etc) headers. The second method is actually advertised and supported by Dovecot. However, I've got quite a lot of friends that lack the knowledge of what the "Subject" field is for, so they just leave it empty. The problem comes when I want Dovecot to return the threads - it follows the ietf draft, so it doesn't check only for references from message headers, but also the subjects. The result is that especially those mails with empty subjects are incorrectly grouped together. So, I'd like to see a feature that would eliminate this problem. It seems to me that there are currently two methods: a) Don't look at the Subject field at all - altough it might increase the speead a bit, it has some disadvantages as well, namely that you'll lose threading if someone uses broken mail client (but broken only in such a way that it preserves subjects) b) Ignore the Subject field if it is empty (after stripping stuff like "re:" etc - just as that draft specifies). Seems reasonable, IMHO. Of course we can't modify the result of a THREAD command (that would break the standard and it generally isn't a proper way to go), so we'd have to introduce another one. I'm pretty sure that especially method a) is very simple (and even simpler if I decided to break the standard by "fixing" the THREAD command), but I really don't like <rant>portable assembler :)</rant> <politely>C</politely>, so are there any chances for this "new and fixed" command to be included into Dovecot? I mean, I might do that in a flawed and ugly way just for me and post a patch so that possible interested persons can pick it, or I migth persuade someone to do it, actually :). Do you think that it's worth the issue? Does anyone have any experiences with talking to the IETF about possible extension of their draft? Ideas?

[Dovecot] Large folders and timeouts
by Fran Fabrizio 11 May '06

11 May '06

I have been having persistent issues with server timeouts on operations on large folders on our Dovecot install (1.0beta2 RPM that came with Fedora Core 5). Some observations from today... I have a Maildir folder with 38,000 messages (it is my Spam folder, naturally :-). In Thunderbird 1.5.0.2, if I click on that folder, it slowly but steadily downloads the headers and after 3-4 minutes, shows me the contents. So far, so good. If I then select all the messages and click Delete to delete them, that operation times out after about 1 minute. If I then click on my Trash folder after some number of minutes has passed, I see that those messages are now both in my Trash and in the original folder - I believe this is because Thunderbird first asks for a COPY over to Trash, and then asks for a STORE +FLAG \\Deleted on the copy that is still in the original folder. It appears that the COPY commands are working but the STORE commands are not since the connection is timing out before they run. I thought I'd try on another mail client, so I tried Squirrelmail. I set it to show 1000 messages per page. It does this just fine. Then I set it to 4,000 messages per page. Then I click on a folder with 12,000 messages, and I get this: ERROR: Connection dropped by IMAP server. Query: SORT (ARRIVAL) ISO-8859-1 ALL My questions are 1. what is the likely cause? and 2. will upgrading to a newer beta address any of this? I'd prefer to wait until FC5 has an updated RPM if possible. Our mail is stored on an NFS store. (I know NFS is slow and that this might be part of the cause.) However, it seems that the timeouts I am having are more related to times when there is no data flowing between the server and client. Note that the timeouts happened when the server was doing a COPY and when the server was doing a SORT but not when the client was downloading 38,000 headers. I'm just at a loss for what to look into next. I don't want to just say "NFS is slow" and live with it if this really has some other cause. :-) So, anyone have any thoughts as to other possible causes? Thunderbird has no option for setting the length of timeout from the client side, so there's nothing I can do from that end.

[Dovecot] Sieve-Editor
by Andreas Martin 11 May '06

11 May '06

Hi all. I'm looking for an editor for sieve-scripts. I tried the Squirrelmail plugin "avelsieve", but it requires "timsieved", wich Dovecot doesn't use. I don't want my users to write sieve-scripts on the console and server-side-filtering is absolutely required. I know that there are some frontends available, but I can't figure out, which one really works with libsieve and is usable for non-geeks... Do you have any suggestions? Thanks, Andreas

[Dovecot] pop3 problem with small messages with no Subject: and no To: headers
by Ken A 11 May '06

11 May '06

Hello, Seeing a strange thing with dovecot 1.0 b7 pop3. If a user gets a particular _very_ short spam message (not sure what virus makes these..), with NO Subject and NO To: headers and NO body, (example available upon request), the user is unable to download the mail. The log entry is: May 10 10:51:35 mail dovecot: POP3(user): Disconnected top=0/0, retr=1/1344, del=0/75, size=16383381 There's no QUIT, so no "Logged out" disconnect reason. I did a tcpdump to see what was happening. I have not been able to duplicate this myself yet, even with an exact copy of the message that seems to be causing it, so it could be a client issue, but I've never seen this before, and we just switched to Dovecot, so I thought I'd check with the list.. ideas? Message #9 is requested (it's the one in the user's box with missing headers). Dovecot begins returning it, but then disconnects, or so it seems. 10:51:35.171916 IP customer.60181 > mailserver.pop3: P 40:48(8) ack 1633 win 65535 0x0000: 4500 0030 d326 4000 7106 fc20 4624 16a1 E..0.&@.q...F$.. 0x0010: ceaa 0f11 eb15 006e 7ee7 2a93 d845 fe0c .......n~.*..E.. 0x0020: 5018 ffff 3618 0000 5245 5452 2039 0d0a P...6...RETR.9.. 10:51:35.172177 IP mailserver.pop3 > customer.60181: P 1633:2980(1347) ack 48 win 5840 0x0000: 4500 056b ca0b 4000 4006 3101 ceaa 0f11 E..k..@.@.1..... 0x0010: 4624 16a1 006e eb15 d845 fe0c 7ee7 2a9b F$...n...E..~.*. 0x0020: 5018 16d0 3fde 0000 2b4f 4b20 3133 3237 P...?...+OK.1327 0x0030: 206f 6374 6574 730d 0a52 6574 7572 6e2d .octets..Return- 0x0040: 5061 7468 3a20 3c68 7469 3935 6b67 6576 Path:.<hti95kgev 0x0050: 4072 @r 10:51:35.416549 IP mailserver.pop3 > customer.60181: P 1633:2980(1347) ack 48 win 5840 0x0000: 4500 056b ca0d 4000 4006 30ff ceaa 0f11 E..k..@.@.0..... 0x0010: 4624 16a1 006e eb15 d845 fe0c 7ee7 2a9b F$...n...E..~.*. 0x0020: 5018 16d0 3fde 0000 2b4f 4b20 3133 3237 P...?...+OK.1327 0x0030: 206f 6374 6574 730d 0a52 6574 7572 6e2d .octets..Return- 0x0040: 5061 7468 3a20 3c68 7469 3935 6b67 6576 Path:.<hti95kgev 0x0050: 4072 @r 10:51:35.470688 IP customer.60181 > mailserver.pop3: F 48:48(0) ack 2980 win 64188 0x0000: 4500 0028 d329 4000 7106 fc25 4624 16a1 E..(.)@.q..%F$.. 0x0010: ceaa 0f11 eb15 006e 7ee7 2a9b d846 034f .......n~.*..F.O 0x0020: 5011 fabc 09fa 0000 0000 0000 0000 P............. 10:51:35.470997 IP mailserver.pop3 > customer.60181: F 2980:2980(0) ack 49 win 5840 0x0000: 4500 0028 ca0f 4000 4006 3640 ceaa 0f11 E..(..@.@.6@.... 0x0010: 4624 16a1 006e eb15 d846 034f 7ee7 2a9c F$...n...F.O~.*. 0x0020: 5011 16d0 ede5 0000 P....... 10:51:35.515279 IP customer.60181 > mailserver.pop3: . ack 2981 win 64188 0x0000: 4500 0028 d32e 4000 7106 fc20 4624 16a1 E..(..@.q...F$.. 0x0010: ceaa 0f11 eb15 006e 7ee7 2a9c d846 0350 .......n~.*..F.P 0x0020: 5010 fabc 09f9 0000 0000 0000 0000 P.............

[Dovecot] Recommended FS for Dovecot Maildir
by Daniel Watts 10 May '06

10 May '06

Hi, I've heard that for Dovecot/Mailir systems there are filesystems that are optimised for the situation of many small files in one folder. Could I possibly have some feedback on what the recommended filesystems are? I've heard of ReiserFS but was wondering what other options there are and how they compare. If I get a good comprehensive response I'll build a wiki summary page out of the data gathered. Best wishes, Daniel

Our mail system consists of dual exim servers processing incoming mail, writing to maildirs on a home- built NFS system. The home-built system is a dual-xeon machine with lots of SATA disks in a RAID5. We then have two client-facing machines running dovecot and squirrelmail. These are all SuperMicro servers running RedHat ES 4. They all use SATA disks. We are using EXT3 for the RAID5 filesystem, and I have had no performance issues to speak of. I had considered Reiser or xfs, but as I have limited experience with either filesystem I didn't feel comfortable using them in production. -- Roger J.

[Dovecot] Debugging with strace
by Fran Fabrizio 10 May '06

10 May '06

We have a dovecot install that is working fine for everyone except one user, who complains that it takes a minute or longer to delete a single message from the INBOX to Trash. This is happening for him from multiple IMAP clients so it appears to be server-side. I wanted to start up a test instance of dovecot alongside the production one and test there. So I copied dovecot.conf, put imap on port 10143, and started up the test server like this: # strace -tt dovecot -F -c /etc/dovecottest.conf (I could not find the docs for -F but without it dovecot would quickly detatch into a daemon and I could no longer strace it... so is -F for putting dovecot in the foreground like I think? :-) I noticed two things when I did this: 1. My screen just scrolled continuously with poll calls - does dovecot poll something every second even when it has no clients connected? 2. It appeared to interfere with the production install running alongside of it - as I could no longer authenticate to it or copy messages to my Sent folder when I sent something out through the production dovecot. I had to restart the production instance to get it to behave. So my questions are whether all that polling output is normal and also, is my testing method really interfering with the production server, and if so, how to avoid that?

[Dovecot] managesieve daemon

Hi, I am currently working on a managesieve daemon, so that I can use the squirrelmail plugin avelsieve together with dovecot-lda. Without this I can't migrate from cyrus to dovecot. For several reasons I don't use the timsieved from cyrus and build it from scratch. Is this interesting for somebody else? Gerald

[Dovecot] Imap folders missing after updating
by Fred Harris 09 May '06

09 May '06

I just updated from 0.99.14 to 1.0beta2 on FC5 and my my IMAP folders have mainly disappeared in my Thunderbird client. All that's left is Inbox and Trash. Is there some configuration setting that's now necessary to make the server think an account uses IMAP folders? The way it seemed to work before was that the presense of a Maildir directory in a user's home indicated IMAP. The new server seems to read the Maildir directory but it doesn't recognize all the folders. Thanks. --------------------------------- Talk is cheap. Use Yahoo! Messenger to make PC-to-Phone calls.

[Dovecot] SIEVE: Any information at all?
by Leah Cunningham 09 May '06

09 May '06

Hi, I am quickly losing the will to live over the lack of any kind of information at all about the SIEVE support that is listed in the dovecot features list. Does anyone have any information at all? I've grepped through the source, looked through all the configuration files, and googled a fair bit and come up with nothing at all. How would a user with maildir enable a sieve script? Does it run on port 2000? How can I test functionality? Thanks, Leah

[Dovecot] Encrypted IMAP only from Internet, unencrypted POP3 from internal network
by Rainer Frey 09 May '06

09 May '06

Hi, we have following situation: I migrated our company mailserver from POP3 only to dovecot with IMAP and POP. We need to have unencrypted POP3 from our internal network, and the subnet our mailserver is in. Additionally, we now want to allow encrypted IMAP from the internet (for some defined accounts), preferably with TLS (which means I open Port 143 in our firewall). Now, how can I achieve that they can't use unencrypted plaintext authentication from Internet, while I allow unencrypted POP3 from the mailserver and private network? (I can require using encryption for IMAP from our internal net, but I must have unencrypted POP3 as we use software that retrieves mail via POP3 that doesn't support encryption). My idea was: - use disable_plaintext_auth for IMAP only - use disable_plaintext_auth for internet, but not our networks - allow connection from the internet only for certain accounts, and limit them to use encryption Internet access for POP3 is not necessary. Is any of this possible with dovecot? Or another way to achieve my goal? Non-plaintext authentication is not possible, as we use linux system accounts with shadow passwords.

[Dovecot] Problem with "INDEX" in default_mail_env, and pop3
by Andrea Dell'Amico 08 May '06

Hello all, I've a problem with maildir, pop3 and relocated indexes. My configuration is: default_mail_env = maildir:%h/Maildir:INDEX=/var/dovecot/index/% u:CONTROL=/var/dovecot/control/%u I created the "/var/dovecot/{index,control}/%u" directories, each one have rights 700 and the ownership is assigned to the user. When the pop clients connect, they fail with the error dovecot: POP3(<username>): mkdir(/var/dovecot/index/<username>/.INBOX) failed: Permission denied I'm using dovecot 1.0.beta7, authentication is pam. I'm using the following settings, too: valid_chroot_dirs = /home:/var/spool/mail:/var/dovecot/index:/var/dovecot/control (last two directories added when i changed the "default_mail_env" setting). Does anybody know what I'm doing wrong? I need to move indexes in a file system without quota. Thanks in advance, andrea -- "Thinking meat!

[Dovecot] Maildir folder hierarchy question
by Richard Leszczynski 08 May '06

08 May '06

Hello all, I am trying to set up Dovecot to use a particular maildir folder hierarchy and have a problem that relates to the inbox. the folder hierarchy I want in /.../Maildir/ is: .inbox cur new tmp .imap.index.files-for-inbox .sent-items cur new tmp .imap.index.files-for-sent-items however the hierarchy that dovecot gives me is .inbox (unused) .INBOX .imap.index.files-for-.INBOX cur new tmp .sent-items cur new tmp .imap.index.files-for-.sent-items I would like to have the (cur,new,tmp) folders associated with the the .inbox placed in the .inbox directory, not alongside it in the main maildir directory. Dovecot appears to do this automatically for other folders. I'm not too bothered if the .inbox folder has to be capitalised. Is this possible? I suspect from reading the Dovecot Q&A that it may not be as the rootdir has special significance with IMAP but I would like confirmation. I've currently set my default_mail_env as: default_mail_env = maildir:/home/%u/mail/maildir:INBOX=/home/%u/mail/maildir/.inbox which I thought should do accomplish what I want but it has no apparent effect. I'm running SUSE 10.0 with Dovecot 0.99.14-5 (as installed by Yast). KMail and Outlook are being used to access Dovecot. Can anyone help? thank you, Richard L ___________________________________________________________ 24 FIFA World Cup tickets to be won with Yahoo! Mail http://uk.mail.yahoo.com

[Dovecot] CVS forked into development/stable branches
by Timo Sirainen 08 May '06

08 May '06

New branch created to CVS: branch_1_0 It's going to stabilize into v1.0 Dovecot, hopefully somewhat soon. I'll start adding new larger features into HEAD, so you might want to switch to branch_1_0 if you're currently using Dovecot from CVS. You can do this with: cvs up -r branch_1_0 The nightly snapshots are from branch_1_0, at least for now.

by Matt Bostock 06 May '06

06 May '06

Hello, We're running Dovecot 1.0.7 on FreeBSD 6.0. Now and then I'll see a POP error ('EOF'), which is remedied simply by restarting Dovecot. Is this a known issue? Kind regards, Matt

[Dovecot] rebuilding dovecot 1.0 beta7 at.src.rpm mysql error
by dave 06 May '06

hi all i'm trying to rebuild the 1.0 beta 7 src rpm from atrpms.net to use mysql 5, instead of mysql 4 but i'm having issues when it gets to the mysql part of the make i have mysql 5 installed (via mysql.com rpm's) i changed the spec file where it says Buildrequires to say MySQL-devel (instead of mysql-devel) but it always comes back with this error, and i don't know what it means, i also tried leaving it as mysql-devel, but still get the same error when i run rpmbuild -ba dovecot.spec && rpm -Uvh --force ../RPMS/i386/dovecot* am i doing this completely wrong, is there something else i need to do to be able to use mysql 5? /usr/lib/mysql/libmysqlclient.a(sha1.o)(.text+0x60): In function `sha1_result': : multiple definition of `sha1_result' ../lib/liblib.a(sha1.o)(.text+0x8e7):/usr/src/redhat/BUILD/dovecot-1.0.beta7/src/lib/sha1.c:233: first defined here /usr/bin/ld: Warning: size of symbol `sha1_result' changed from 191 in ../lib/liblib.a(sha1.o) to 126 in /usr/lib/mysql/libmysqlclient.a(sha1.o) collect2: ld returned 1 exit status make[3]: *** [dovecot-auth] Error 1 make[3]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta7/src/auth' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta7/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/src/redhat/BUILD/dovecot-1.0.beta7' make: *** [all] Error 2 error: Bad exit status from /var/tmp/rpm-tmp.84952 (%build) thanks dave -- http://dtracorp.com

[Dovecot] Sending email over IMAP?
by Marc Perkel 06 May '06

06 May '06

I'm advocating for a change in the IMAP specification to allow outgoing email to be sent over the same connection as incoming rather that having to separately configure outgoing SMTP email. There are two significant advantages to this concept. 1) It would greatly simplify setup for clients as they would only have to configure one connection rather than two. 2) Spam reduction by authentication. The sending of email over the same connection tells the server that the person who is the sender of the email also has demonstrated they have access to read the account. This would be a powerful whitelisting criteria for eliminating fake senders. So - my question. It seems that it would be easy to do this if there were a standard. Dovecot would merely hand incoming email off to the outgoing SMTP server. Besides the difficulty of getting a standard created, am I right on my assumptions?

[Dovecot] UID and GID problems
by Simon Windsor 06 May '06

06 May '06

Hi I have been using dovecot for a while now to support a number of virtual users via a postgres table. The dovecot user chown is dovecot:dovecot, and for each domain, I use a single GID, so for example domain1 is 1001:dovecot, domain2 is 2001:dovecot. All directories are owned by 1001:dovecot or 2001:dovecot. The works well most of the time, but occasionally, some user files are owned by dovecot:dovecot, and others by gid:dovecot. Is this a know issue? Any help would be appreciated. Simon -- Simon Windsor Eml: simon.windsor(a)cornfield.org.uk Tel: 01454 617689 Mob: 07960 321599

[Dovecot] dovecot LDA w/virtual domains and postfix
by Leah Cunningham 05 May '06

05 May '06

Hi, I've been trying to follow the documentation that I am finding, but am running into trouble getting things set up correctly for postfix + virtual domains (using ldap) with dovecot LDA. I can get it to work without LDA, but I'm running into permissions problems when I try to run with LDA. I am wondering if anyone has any good examples of configuring this. I basically have a 'vmail' user (1015) that owns a /var/vmail/domains directory tree. I have set the following in postfix master.cf: # Dovecot LDA dovecot unix - n n - - pipe flags=DRhu user=vmail:mail argv=/usr/lib/dovecot/deliver -d ${recipient} In main.cf dovecot_destination_recipient_limit = 1 virtual_transport = dovecot virtual_mailbox_base = /var/vmail/domains virtual_mailbox_maps = ldap:/etc/postfix/ldap-mailbox.cf virtual_mailbox_domains = ldap:/etc/postfix/ldap-vdoms.cf virtual_uid_maps = static:1015 virtual_gid_maps = static:12 home_mailbox = Maildir/ and in dovecot.conf: protocols = imap imaps pop3 pop3s ssl_disable = no ssl_cert_file = /etc/ssl/certs/sauerkraut.heinous.org.crt ssl_key_file = /etc/ssl/private/sauerkraut.heinous.org.key mail_extra_groups = mail valid_chroot_dirs = /var/vmail/domains default_mail_env = maildir:/var/vmail/domains/%d/%n/mail protocol lda { postmaster_address = postmaster(a)frauerpower.com } protocol imap { } protocol pop3 { } auth default { mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } user = root } auth default_with_listener { mechanisms = plain userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } socket listen { master { path = /var/run/dovecot-auth-master mode = 0600 user = vmail group = mail } } } plugin { } However, I must be missing something. I get the following when trying to send the user a message: setuid(1015) failed: Operation not permitted Doing 'postmap -q leah(a)frauerpower.com ldap:/etc/postfix/ldap-mailbox.cf' returns 'frauerpower.com/leah/mail/' which, in the non LDA mode worked okay, plonking the mail under /var/vmail/domains/frauerpower.com/leah/mail How is this sort of thing normally set up? Apologies in advance for my ignorance, I am pretty new to dovecot. Leah

Saving Direct to Shared Mailbox (Was: Re: [Dovecot] Sending email over IMAP?)
by Timothy White 05 May '06

05 May '06

Thinking along similar lines to this sending email via IMAP... What I am thinking, is using Shared Folders/Mailbox's, like mailing lists. We have the power of ACL's, and if you have the appropriate permissions, you can 'append' emails to the folder. Except, when you think of a mailing list, you usually just hit reply. One of the projects I am working on, will be setup with a number of shared folders, an 'official' folder that everyone has read access to, (probably thier own index files as well, so the Seen flag isn't global), and a few admins have write access to. The problem still comes, as to the easiest way to 'send emails' to the folder. I could set up a virtual user, that delivers to that folder, but then you need a second system of ACL's that determine who can send emails to the folder.... Unless, Dovecot LDA handles that.... So, other than lack of client support for saving directly to a folder, instead of sending to a folder... Can Dovecot LDA do what I want, or be made to do what I want? I have no problems having a 'virtual' user that people send the emails to, as long as Dovecot LDA will handle the ACL's for it as well. Any ideas of how to solve this problem, or if Dovecot LDA can/will do it? Tim -- Linux Counter user #273956

[Dovecot] Bug in yesterday's CVS..
by Apps Lists 05 May '06

05 May '06

Hi Timo. I'm doing some testing with yesterday's CVS code and believe I've found a bug. In SquirrelMail, I get 5 messages in INBOX (doesn't matter how). I click "Toggle All" then "Delete". All 5 messages move to Trash. The Trash folder gets a link "expunge". I click that and get the following error: ERROR : Bad or malformed request. Query:STORE 1:6 +FLAGS (\Deleted) Server responded: Error in IMAP command STORE: Invalid messageset There are 5 messages in Trash, not 6. After this error is displayed, I see the following in syslog: May 2 09:37:24 dev3 dovecot: IMAP(jtest): Fixed index file /var/mailstore/72/af/375887/Maildir/.Trash/dovecot.index: first_recent_uid_lowwater 10 -> 9 (this might not actually be the right message for the error, but it's always first_recent_uid_lowwater getting decremented by 1) If I hit refresh in the browser, I can then click Expunge without issue once first_recent_uid_lowwater is fixed. I am able to replicate this easily in NFS, GFS (cluster) and local disk. Steve

Howdy, I've been working with a new CentOS installation and this is my first experience with dovecot. I would like dovecot to provide more logging, however I'm not finding much on how to alter it's logging. http://wiki.dovecot.org/DovecotFeatures speaks of having Logging Control. Can anyone point me in the right direction? Thanks. -- Edward Chase Providence College Information Technology
