[Dovecot] '+' addesses and Foldered delivery
by Brad 21 Feb '06

21 Feb '06

Before I start tearing my hair out .. I am using sendmail 8.13.5 with the exact setting for the dovecot lda specified in the dovecot wiki. Does the mailer definition for the lda ensure that it can understand +'ed addressing for foldered delivery ?

[Dovecot] Dovecot lda woes

Having some painful problems with the dovecot lda and getting it to (a). Just work (b). Work with sendmail This is how I have dovecot setup (appropriate dovecot.conf snippets included) protocol lda { module_dir = /usr/local/lib/dovecot/lda postmaster_address = postmaster(a)bradphinney.com auth_socket_path = /var/run/dovecot-auth-master } auth default { .... # passwd-like file with specified location passdb passwd-file { # Path for passwd-file args = /etc/dovecot-passdb } userdb static { args = uid=500 gid=500 home=/var/mail/%u mail=mbox:/export/dovecot/%d/%u/ nice=10 } ... } Here is what deliver is set up as -rwsr-sr-x 1 dovecot dovecot 2070623 Feb 19 18:22 deliver* I drop sendmail into debugging mode so I can at least see if it is resolving the address correctly. Here is my mailertable entries : testdomain1.com dovecot:dovecot I fire up sendmail. telnet to port 25 and see if I cant get some mail delivered. Here is what sendmail spits out Feb 20 18:54:18 titan sendmail[6475]: k1KNqWti006459: to=<echo(a)testdomain1.com>, delay=00:01:16, xdelay=00:00:00, mailer=dovecot, pri=120016, relay=dovecot, dsn=5.3.0, stat=unknown mailer error 89 Not good.

[Dovecot] Problems with authentication
by Lapo Luchini 20 Feb '06

20 Feb '06

Hi there. I've got a running qmail+vpopmail+mysql5 server on FreeBSD and I would like to give IMAP access to it (both for user's sake and to have a decent webmail), so I decided to install dovecot (it certainly does its work on my home box). Problem is: I haven't had success with authentication. At first I tried the most obvious: using the vpopmail backend. Unfortunately I received lots of "vmysql: MySQL server has gone away" just like in http://article.gmane.org/gmane.mail.imap.dovecot/10321 So I decided to spice up a query to vpopmail's MySQL table, and there another problem was waiting for me: "Access denied" just like in this thread http://article.gmane.org/gmane.mail.imap.dovecot/9077 Only difference: in my case using OLD_PASSWORD() didn't solve the problem and -thinking about it better- couln't possibly have solved it: that FreeBSD is a recent fresh install and I installed MySQL 5.0.18 from sources using the "ports" system, so a library with no support for new PASSWORD() has never seen the light on that box. I kinda went around the problem using a shell script to dump the MySQL table to a SQLite file and authentication dovecot against that, but while this work-around can do for a little bit I'd really like to solve the problem itself, and avoid having to keep ni sync those two DBs (no, unfortunately vpopmail doesn't support SQLite, else I'd use that: it would also have the nice side-effect that a "down" on mysql side wouldn't hurt the mail subsystem). Any suggestions or idea how I could solve or, at least, better diagnose the problem(s)? Yours, Lapo

[Dovecot] rawlog for Dovecot proxies
by Bill Boebel 20 Feb '06

20 Feb '06

Is there a way to use rawlog to log the full IMAP session when running Dovecot as a front-end proxy for other IMAP servers? If so, how?... I couldn't figure it out. Or is there another debug setting that can give me this information? If not, what is the best method to sniff the IMAP session for debugging a proxy?... ethereal? Thanks, Bill -- http://billboebel.typepad.com/

Hello! I was looking for some information about which signals I can send to dovecot to do various things, but I couldn't find it. Since it's a wiki, is it ok to just edit the pages, or should I post here first? I thought I'd check with Timo and you guys first, maybe I missed that page that describes the signals... If it's ok, I can edit or add a new page. /Peter -- Peter Lindgren, dataingenjör E-post: peter "at" norrskenkonsult punkt com http://www.norrskenkonsult.com

[Dovecot] IMAP stress testing tool
by Timo Sirainen 20 Feb '06

20 Feb '06

I updated my IMAP stress testing tool to support also APPENDs and print some nice statistics. If you want to try for yourself, it's here: http://dovecot.org/tools/imaptest.c I thought about adding some more features in future to it, such as: - Add a header to each appended message containing MD5 sum of it. When fetching, verify that the MD5 sum is valid. - Do randomized fetch requests (headers, size, flags, etc.) - Do randomized search requests - sort, thread

[Dovecot] Messages disappear and reappear when I check mailbox using KMail
by Lincoln Peters 20 Feb '06

20 Feb '06

Not sure if this is a Dovecot bug or a KMail bug, but since it only seems to happen to people using KMail to access a Dovecot server or a Novell NetWare IMAP server, I thought I should mention it here. <http://bugs.kde.org/show_bug.cgi?id=121866> From the bug report: When I check for mail on an IMAP account (not disconnected), all recently-received messages disappear prior to any mail check, any new messages appear, and then the messages that disappeared earlier reappear. This does not seem to cause any harm, but it is horrendously inefficient if there are a lot of messages in an IMAP folder so affected. Any ideas as to what could cause this behavior in a mail client when connecting to a Dovecot IMAP server but not when connecting to other kinds of IMAP servers? -- Lincoln Peters <sampln(a)sbcglobal.net> BOFH excuse #80: That's a great computer you have there; have you considered how it would work as a BSD machine? /~\ The ASCII Ribbon Campaign \ / No HTML/RTF in email X No Word docs in email / \ Respect for open standards

[Dovecot] IMAP and Outlook XP Contacts
by DiskMan 20 Feb '06

20 Feb '06

I was wondering, does Dovecot's IMAP server hand Outlook XP's contact lists? I tried to enter a contact on my IMAP server and received an error from Outlook stating that the Contacts formatting was too complex and thus couldn't be saved. I went ahead and swung my box over to MailDir and scrapped Sendmail for Postfix [for maildir support], I was wondering, would this issue continue? In other words, by swinging over to MailDir, would Dovecot be able to handle Outlook's Contacts information? Will L G

[Dovecot] Another permissions problem?
by Anne Wilson 19 Feb '06

19 Feb '06

The rebuild server is now almost complete. Dovecot is running, and I can telnet and log in. In kmail on this workstation I have created an imap account, for which Inbox was created. I also created Trash and sent-mail as top-level folders, and they display correctly with the cur, new and tmp sub-folders on the server. I now want to create subfolders of Inbox, and there I'm coming unstuck.

[Dovecot] Login processes don't die
by Jürgen Herz 19 Feb '06

19 Feb '06

Hello, I'm a fresh dovecot user (resp. admin), using dovecot 0.99.14 (a little old, but that's what Debian Sarge provides). In general everything works as it should, but there's something that makes me wonder. The wiki says "By default each login process will handle only a single connection and afterwards kill itself." But it does look different to me. On startup there are two imap-login processes running (login_processes_count is 2). When connecting with Sylpheed, one additional imap process is running. But when connecting with Mozilla (Seamonkey), I get three imap-login and one imap process at minimum (Maximum number of server connections to cache set to 1 in Mozilla). If the cached connections is set to 2, there are four imap-login and two imap processes. So it looks to me as the login processes don't get killed. Is this a client issue (but how could it keep the login alive?), is this a known bug in the older dovecot, or something unknown? BTW, login_process_per_connection is default. Regards, Jürgen

[Dovecot] Second user problems
by Anne Wilson 18 Feb '06

18 Feb '06

I have dovecot (0.99.14 under FC4) set up and working beautifully for my mail, handing on to procmail, and handling many subfolders. Today I needed to set up a second user. I added his account in kmail and created a sub-folder, but no sent-mail, trash etc. were created. I have sent test messages and /var/log/maillog says they have been processed, but they are not arriving in his inbox. /var/log/mail.info shows that he has logged in to dovecot. He has a simple .procmailrc to handle the one subdirectory. I'm sure that it must be something I've missed in dovecot.conf, but I can't see anything there that shouldn't work just as well for him as it does for me. Any pointers? Anne

[Dovecot] Growing pools and disconnects

[Dovecot] Authentication failing - Ant Internet Suite (Risc-OS)
by Simon Waters 17 Feb '06

17 Feb '06

Switched to using dovecot for POP3, PLAIN login. One client with "Ant Internet Suite" can't use the service with this client, he used the same setting with another email client and it worked. On inspection of the packets, it is sending one packet with; "user username\r\npass password\r\nstat\r\n" Dovecot sends an "-ERR Unknown command", then a "+OK Logged in". I'm wondering if things got out of sequence here, since a "STAT" to dovecot before authentication causes the "Unknown command" error. "STAT" isn't allowed in the authentication stage... but well it issued it last.... Anyway I'm unclear here on the precise details of the packet trace, possible it is responding to an earlier packet, but thought I'd ask before pursuing this further in case some one leaps up and says "oh that'll be...". The client software has an option to disabled "queued commands" buried deep within it (append /ucb to user details), I suggested trying this if possible, will report back if it works. Also mentioned in a Google search. I'm curious as to what is right here, but the "/ucb" is presumably the practical answer if it works. Simon

[Dovecot] 1.0beta3 released
by Timo Sirainen 17 Feb '06

17 Feb '06

Since there have been so many requests, I guess it's time for beta3 now. There are a couple of issues that I'm still concerned about, but those probably happen with beta2 as well. If you're beginning to see more connection hangs/timeouts with this release, please tell me. * Dotlock code changed to timeout faster in some situations when the lock file is old. + Added support for loading SQL drivers dynamically (see INSTALL file for how to build them) + Keywords are stored to dboxes, and other dbox improvements. + dict-sql could actually work now, making quota-in-sql-database possibly working now (not fully tested) + Added mail storage conversion plugin to convert automatically from one mailbox format to another while user logs in. Doesn't preserve UIDVALIDITY/UIDs though. + Added plugin { .. } section to dovecot.conf for passing parameters to plugins (see dovecot-example.conf). + Added ssl-build-param binary which is used to generate ssl-parameters.dat. Main dovecot binary doesn't anymore link to SSL libraries, and this also makes the process title be clearer about why the process is eating all the CPU. - Fix building without OpenSSL - Fixed memory leak in MySQL driver - Fixes to checkpassword - Broken Content-Length header could have broken mbox opening - Fixed potential hangs after APPEND command - Fixed potential crashes in dovecot-auth and imap/pop3-login - zlib plugin now links with -lz so it could actually work - kqueue fixes by Vaclav Haisman

[Dovecot] ugly hack to make maildir quotas work

Timo encouraged me to forward this to the list. Basically it pokes the right value into the right place to make quota deltas work properly when saving mail to Maildirs.

[Dovecot] Question regarding 'dovecot-auth'

Hello Timo, I am compiling dovecot-1.0.beta3, and I get the following message when the dovecot-auth module is being compiled: Undefined symbol sql_drivers_register_all first referenced in main.o Now I had run 'configure' with the '--without-sql-drivers' since I neither have MySQL or PostgresSQL installed on my server. Does this mean I DO have to get either package, install, and run it '--with-sql-drivers'? Or is it that the '--without...' feature doesn't work as intended? Am I making ANY sense? Thanks.

The configuration files has settings that seem to address the issues of using indexes on NFS (i.e. locking and mmap fixes), but we are using Dovecot on NFS, and when the load gets high we start to see a lot of NFS stale file handle errors, particularly with MS clients like Outlook. I see the discussion about these errors from last year. Any updates on the state of the code? Should we be using in-memory or local indexes instead for now? - Dovecot 1.0b3 - four physical IMAP servers - mbox format accounts on NFS netapps - currently allowing NFS indexes w/mmap disabled, and using dotlocks -- Anthony Kay University Computing Center (541) 346-1719 GPG Fingerprint: B0DB D46A 60AF FAE7 A94A 5075 0CB4 4D88 9F4F 7F09 Perfection uncanned Like a beautiful redhead Fresh from her trailer from Spam-Ku : Tranquil Reflections on Luncheon Loaf by John Cho

[Dovecot] imap_capability setting
by Bill Boebel 15 Feb '06

15 Feb '06

In src/master/master-settings.c, there is a config variable "imap_capability" that is read in from the conf file... but in the rest of the code it looks like that variable is never used. I assume this is there for future use, but just wanted to confirm that the code not using it was intentional. Since we are using Dovecot as an IMAP proxy for a Courier backend (for now), we need to advertise a different capability string than the Dovecot default. I have changed the hardcoded value in the ./configure script (@ 31015) for now. Bill

[Dovecot] Dovecot RFC non-compliance: Mailbox names
by Tony Kay 15 Feb '06

15 Feb '06

Hi, I think I already know the answer to this and I agree with it, but I have a question about "invalid" mailbox naming decisions in dovecot. Technically, RFC3501 (Section 5.1, pg. 18, client consideration 3) says that * and % are legal in mailbox names, though it implicitly discourages their use. We just migrated to dovecot, and unfortunately have a few users who used * in their mailbox naming (which worked on our old IMAP server). I looked in the mailing list and source comments, but I could not find any discussion. Was there any discussion about the imap/commands-util.c:48? 46: /* make sure it even looks valid */ 47: sep = mail_storage_get_hierarchy_sep(storage); 48: if (*mailbox == '\0' || strspn(mailbox, "\r\n*%?") != 0) { 49: client_send_tagline(cmd, "NO Invalid mailbox name."); which is technically not RFC-compliant? I have a feeling it fixes much more important things than it breaks (i.e. LIST/LSUB), but then again we never had complaints from people using those characters in names until they stopped being supported. -- Anthony Kay University Computing Center (541) 346-1719 GPG Fingerprint: B0DB D46A 60AF FAE7 A94A 5075 0CB4 4D88 9F4F 7F09 Sanity is a cozy lie.

[Dovecot] dovecot-LDA and fromwho-argument
by Björn Ketelaars 15 Feb '06

15 Feb '06

Hello, Im using dspam 3.6.3 in combination with Dovecot, procmail and Sendmail. Everything works fine but I want to replace procmail by dovecot-LDA. A few changes to dspam.conf results in a takeover by dovecot-LDA. Unfortunately this is where it goes awry; besides the d argument (user), dspam also supplies the f argument (fromwhom). The use of the f argument results in an error because dovecot-LDA does not know what to do with it. Is there an option to ignore the passing of 'fromwhom' from dspam? -- In individuals, insanity is rare; but in groups, parties, nations and epochs, it is the rule.

[Dovecot] Message index corruption when using Thunderbird and Dovecot
by Reuben Pearse 14 Feb '06

14 Feb '06

Hi all, I have recently upgraded from UW-IMAP to Dovecot 1.0.beta3 on Redhat9. I migrated my mailbox to from Mbox to Maildir using the mb2md perl script, and created a procmail recipe file to get email arriving in the Maildir directories. However, when accessing my mailbox from Thunderbird (version 1.5), it occasionally mixes up the email header with the email content. I also occasionally get errors like this when clicking on old messages (ones that got converted as part of the mb2md script). The current command did not succeed. The mail server responded: Error in IMAP command UID: Invalid BODY[..] parameter: Missing '>' in '<16384.-15744>' However, if I click on the email item again, Thunderbird is then able to retrieve the message correctly. Can anyone provide some help with these problem.

[Dovecot] Re: Mail.app help
by Roger Weeks 14 Feb '06

14 Feb '06

I'm wondering if this is a version issue with Mail.app? Are you on OS X 10.3 or 10.4? The reason I ask is that we also migrated from Courier IMAP to Dovecot 1.0alpha5 and then beta3, and we did not have this problem with Mail.app that either of you are describing. I did have to remove the "INBOX." prefix from my Mail.app configurations. I also renamed all of the existing folders in my Maildir from INBOX.foldername to .foldername, because after removing the "INBOX." prefix Mail.app could not see them. Before I renamed all of the existing folders and changed the prefix in Mail.app, I had also tried setting up alternate namespaces as described in the wiki documentation for converting from Courier, but that did not seem to work. Mail.app and Thunderbird clients could not see their IMAP folders with the courier-style namespace configuration. -- Roger J.

[Dovecot] Dovecot-1.0.beta1: New mail sometimes fails to appear
by Tom Alsberg 14 Feb '06

14 Feb '06

Hi there... Having updated to 1.0.beta1, I for a while thought a bad bug with IDLE handling that caused new mail in INBOX not to appear when using Mozilla Thunderbird has been solved. Although I can not reproduce one kind of problem anymore, after a short while it again appears that one does not always see one's new mail with Thunderbird. I can not consistently reproduce the bug, but from some network captures it indeed appears that sometimes Thunderbird has (in one of its connections to the server) INBOX SELECTed and IDLE on it, new mail arrives, but 10 minutes afterwards it was still not sent an EXISTS message. Initially the symptoms appeared to suggest that something really bad happened to the index files, but I tried INDEX=MEMORY and that did not help much. Thunderbird using multiple connections to the server does of course only make debugging more difficult. But it appears that without multiple connections, one has to constantly cycle around SELECTing to get notified on more than one mailbox, so that may justified. I am a bit lost on this now, and would appreciate some ideas. Although there were several related bugs I noticed in Thunderbird 1.0, it appears that they are gone in 1.5, and yet now it really seems Dovecot is doing something wrong here. Attached is the configuration file I use for the testing installation of Dovecot 1.0.beta1 (somebody tell me if you see something wrong there). The mailbox arrangement is as follows, right now (until we have a better way): * INBOX in /var/mail/%u * most mailboxes in ~/imap.maildir/... as maildirs. * mboxes in ~/imap.mbox/... accessible as #imap.mbox/... * the mbox:~/mail/ is for when namespaces are not used - now there are so it should not be relevant Except for myself, and one test account I have, I have two guinea-pigs using it (who are well aware that it is still under development and that it will break once in a while) and reporting problems to me. Vaguely (since I can't figure the exact reasons), the symptom can be described as follows: When using Mozilla Thunderbird to access mail, new mail arrives to INBOX (mbox:/var/mail/%u), but is sometimes not seen for a long while after it arrives. Sometimes the first (or first few) message arriving appears, but then no new messages appear, and sometimes everything works right and immediately new mail is seen. However whenever (according to Thunderbird) something changes in the mailbox, the mailbox is seen up-to-date as it really was at that time.

[Dovecot] Mail.app help
by Mike Garfias 14 Feb '06

14 Feb '06

I'm having a problem with Mail.app and imap folders. I've got a new install of dovecot 1.0beta2, and am only experiencing this problem with Mail. Mutt works as expected, as well as thunderbird. When I create a folder using Mail.app, it is written to ~/Maildir/.INBOX.newfolder, which would be fine, if I wasn't telling everything that I wanted no prefixes. If I move that folder to ~/Maildir/.newfolder, Mail.app can no longer see it, but mutt and thunderbird can. Thunderbird _CAN_ see the folders created as .INBOX.Folder, and even shows it as a subfolder of my inbox, but Mutt completely refuses to see it. Any ideas what I'm doing wrong here?

I need to be able to setup a nologin system for users on my mail server on a per user basis. We are going to do some maintenance on each user (individually) and would like it if they could not login to dovecot while we do this. I was curious if dovecot implemented anything like this. We are currently using standard pam authentication (nothing db related) and I was hoping to be able to touch a "nologin" file on a per user basis in their home directory. I think I could do this with some pam magic, but was curious if dovecot had something in it that would allow for this. Note: I understand I will have to forcibly kill active connections. --Robert

[Dovecot] Problems with POP3 UIDL when migrating from MBOX to Maildir
by Jonas Olsson 14 Feb '06

14 Feb '06

Hello, I am in the process of migrating a hosting setup from UW-IMAP to Dovecot. The protocols available to mail clients are IMAP and POP3 both before and after migration. I also wanted to change the mail storage format from MBOX to Maildir. However, at this point I hit a major snag with Dovecot and POP3 UIDL (unique identification listing for POP3 mailboxes). Several of the customers connecting to the mailserver in question are using POP3 clients and leave their e-mails on the server. To avoid downloading all messages every time the clients connect they use the UIDL command in the POP3 specification to determine if any new messages have arrived since last time they checked. In order for this to work the unique identifier of each message must be static and can never change. If the identifiers change, every client will download all messages again, mixing old messages with new, in the belief that all messages are new since their identifiers changed. The first step, migrating from UW-IMAP to Dovecot, did not pose any problems in this regard. Connecting to the POP3 service manually to show the UIDL output revealed: With UW-IMAP: uidl +OK Unique-ID listing follows 1 43ef424e00000001 2 43ef424e00000002 With Dovecot: uidl +OK 1 43ef424e00000001 2 43ef424e00000002 However, after performing a migration to Maildir, storing all messages in ~/Maildir for the user in question, I received a different UIDL output: uidl +OK 1 43ef523100000001 2 43ef523100000002 I used the mb2md utility available from http://batleth.sapienti-sat.org/projects/mb2md/ to do the conversion.

[Dovecot] IMAP timeout
by Eugeny N Dzhurinsky 14 Feb '06

14 Feb '06

Hi there! Is it possible to set timeout for IMAP connection somehow? The problem is when I'm using mutt to access IMAP mailbox, everything works fine, but after some idle time mutt tells mailbox is closed and next connection crashes it. With courier mutt works just fine, so I think may be dovecot have some timeout which need to be adjusted? I checked manuals and configuration, but no luck... In both cases (dovecot/courier) I'm using IMAP over SSL -- Eugene N Dzhurinsky

[Dovecot] imap process spinning (ix86/OpenBSD 3.8, dovecot 1.0b3)
by Joseph Kiniry 13 Feb '06

13 Feb '06

Hi Dovecot-ers, Immediately on accessing our new dovecot 1.0b3 build, we see processes spinning, much like the old dovecot 0.9x builds did for us. Here is a ktrace of the spinning imap process: topos:tmp# kdump 18248 imap EMUL "native" 18248 imap PSIG SIGALRM caught handler=0x1c03ff88 mask=0x0 18248 imap CALL setitimer(0,0xcfbcb3bc,0xcfbcb3ac) 18248 imap RET setitimer 0 18248 imap CALL sigreturn(0xcfbcb3ec) 18248 imap RET sigreturn JUSTRETURN 18248 imap PSIG SIGALRM caught handler=0x1c03ff88 mask=0x0 18248 imap CALL setitimer(0,0xcfbcb3bc,0xcfbcb3ac) 18248 imap RET setitimer 0 18248 imap CALL sigreturn(0xcfbcb3ec) 18248 imap RET sigreturn JUSTRETURN If any additional config information is needed to debug, just ask. I am now subscribed to (the digest version of) this list. Thanks, Joe --- Joseph Kiniry School of Computer Science and Informatics UCD Dublin http://secure.ucd.ie/ http://srg.cs.ucd.ie/

[Dovecot] locking problems with RHEL 3 and dovecot
by Dan Bongert 13 Feb '06

13 Feb '06

I just migrated from a FreeBSD/Sendmail/UW-IMAP setup to RHEL 3/Postfix/Dovecot (1.0a5 currently). Both systems used Procmail as the final delivery agent (into inboxes or . Since the changeover, things have *mostly* been going ok, but I've been having some problems that I think are locking-related. I'm getting reports from users about IMAP hangs (mostly from Thunderbird). Sometimes I see this in the Dovecot logs: ovecot: Feb 06 11:30:45 Error: imap(dbongert): fcntl() failed with mbox file /home/d/dbongert/mail/worklists/tech-partners: Resource temporarily unavailable Now, I have read that one should have everything that touches a mailbox use the same sort of locking, but that's the thing--these mailboxes are only accessed via dovecot. I'm sure a few users use procmail to filter their mail, but they're in the strict minority here. As as experiment, I changed these lines to flock rather than fcntl: mbox_read_locks = flock mbox_write_locks = dotlock flock But all that seems to have done is removed the fcntl errors from the log file. These errors seem to be Thunderbird only (1.07-1.5, Linux and Windows clients), but I'm not sure what that means. I've enabled the only thunderbird-specific IMAP workaround I know of: tb-extra-mailbox-sep, but I doubt that has anything to do with this problem. -- Dan Bongert dbongert(a)ssc.wisc.edu SSCC Unix System Administrator

I would not use it these days. Before we switched to SMTP AUTH, we were also using a POP-before-SMTP model, yet we dropped it immediately when one of our customer's network had been compromized by a virus and due to POPb4SMTP the virus distributed itself using our mailserver without limitation.

[Dovecot] drac.c
by Takehiko Abe 13 Feb '06

13 Feb '06

Hello, I am using dovecot [1.0 beta3] as a pop server with drac. It is working nicely, but I am getting the following message in a log: dovecot: pop3(keke): file ioloop.c: line 154 (timeout_remove): \ assertion failed: (*timeout != NULL) dovecot: child 15752 (pop3) killed with signal 6 Adding '&' to 'to_drac' in drac_deinit of drac.c stops the message: void drac_deinit(void) { if (to_drac != NULL) timeout_remove(&to_drac); /* was to_drac */ } But I am not sure if the mod is correct. Thanks, T.

[Dovecot] Maximum Folder Size/Number of Messages
by Ropetin 13 Feb '06

13 Feb '06

I hope I'm asking this question in the right place, I don't want to offend. I've recently put together a proof of concept Dovecot IMAP server, and I'm very happy with its performance up to this point. I'm looking into using it to replace our existing POP3 server, allowing users to store email on the server rather than on their local machine, hopefully avoiding loss of data. The big question I have is, is there a realistic maximum realistic folder size, either in reference to number of messages or total file size with Dovecot? I'm using Maildir and running it on Debian Linux x86. Right now the filesystem is Ext3, although once the system goes live I'd be looking at something a little more fault tolerant and able to handle the large amount of data. Any recommendations you may have on Filesystem choice are appreciated too! Thanks, Ropetin.

[Dovecot] LDA delivery problem
by Martin Stephan 12 Feb '06

12 Feb '06

Hi I compiled and configured dovecot-lda as explained in the Wiki (current CVS version). Now I get the following error message: Action: failed Status: 5.0.0 Diagnostic-Code: X-Postfix; Command died with status 80: "/usr/local/libexec/dovecot/deliver". Command output: deliver: Fatal: Can't open log file /var/log/dovecot.log: Permission denied Now, do I have to set this socket listen { master { path = /var/run/dovecot-auth-master mode = 0666 user = vmail # User running Dovecot LDA group = vmail # alternatively mode 0660 + LDA user in this group } } to something else? Or chown the log file? I use Postfix and Dovecot on Ubuntu Breezy. Thanks Martin
