[Dovecot] size of "m.XXX" in mdbox
by Joan Moreau 10 Jan '11

10 Jan '11

Hi, How to tune the size of each "m.xxx" file in mdbox format , in order to optimize the ratio size/number of files ? (I can see for instance more than 100 000 files in one directory due to very large mailbox size) If such parameter exists, what is the typical value ? Thanks Joan

Or use sendmail binary from something else than Courier. Yes i'm using sendmail from Courier. When i changed sendmail_path to original sednmail binary it's working and vacation is sent, but i can see some errors from sendmail.

[Dovecot] CatchAll virtual user removes spamheaders
by Peter Reinhold 09 Jan '11

09 Jan '11

Hi all, I am having a small problem with a catch-all user I have setup in my Postfix/Dovecot setup. I am not 100% sure this is Dovecot related, but, logic tells me it is. I have a virtual user called @reinhold.dk setup to redirect to my main account, peter(a)reinhold.dk. If I send a spam mail (GTUBE) to peter(a)reinhold.dk, the mail is marked with Amavis x-headers as it should be. If I send the same mail to peterpeter(a)reinhold.dk, I can see in my maillog that the mail is PASSED SPAMMY, just as the first one, but when I check the mail, all amavis x-headers are missing. (Except one, X-Spam-Virus-Scanned:, which just informs me that the mail has passed through the scanner) Does anyone know if this is a Dovecot issue? (It seems so to me), and if so, any hints on how I can change this behaviour? Kind Regards, Peter Reinhold - peter(a)reinhold.dk > http://www.reinhold.dk & http://www.geekhouse.dk < -- QOTD : Mit internet er der ikke noget porn på .. Det er helt vildt nederen. ..

[Dovecot] can not receive external emails
by Daminto Lie 09 Jan '11

09 Jan '11

Hi, I am new to Dovecot. Recently I have got a new server running on Ubuntu Server 10.04 with Postfix, Dovecot (for IMAP) and Squirrelmail. During the test, I was able to send & receive emails internally, and can send emails externally. However, I got a problem when it comes to receiving emails externally. The emails I sent from yahoo never arrived to my local inbox. Anyway, I checked the mail.log and found the following dovecot: auth-worker(default): dovecot-auth: /usr/locallib/liblber-2.4.so.2" no version information available (required by dovecot-auth) dovecot: auth-worker(default): dovecot-auth: /usr/locallib/libldap_r-2.4.so.2" no version information available (required by dovecot-auth) dovecot: auth-worker(default): dovecot-auth: /usr/locallib/libldap-r-2.4.so.2" no version information available (required by /usr/lib/libpq.so.5) I was wondering if anyone might be kind to explain the above error messages and how to work around this so that it could send/receive emails coming from external mail server. Thank you in advance

Has anyone tried patching the 1.2.x source to force logging of all passwords submitted during authentication, not just those that fail?

[Dovecot] IMAP Clients can not see 3rd tier nested IMAP directories
by jjs87＠cornell.edu 08 Jan '11

08 Jan '11

I have a very bizarre problem that I hope someone can help me with. I am not sure if this is a Dovecot problem, or IMAP client problem. I recently used Transend's Migrator to move mail from Exchange 2007 to my Dovecot 1.0.7 server. The program seems to have moved the nested IMAP dirs properly as seen below in a directory listing of the maildir dir. The nested dirs have indexes, cur, new dirs as expected. However, when the account is viewed in Windows Thunderbird 3.1.6 or Outlook 2010 the 3rd tier dirs are not seen, nor can they be subscribed to. On a whim, I decided to try Apple Mail 4.3 to view the account and all the IMAP dirs can be seen and accessed as expected. Any idea what is going on? Is this somehow an IMAP client problem (bug) or an issue with Dovecot and these clients? Listing of the Maildir dir: [root Maildir]# ls -al total 92 drwx------ 17 andrew andrew 4096 Dec 6 17:06 . drwx------ 9 andrew andrew 4096 Dec 6 15:58 .. drwx------ 5 andrew andrew 4096 Dec 6 16:31 .mailbox drwx------ 5 andrew andrew 4096 Dec 6 16:31 .mailbox.mail drwx------ 5 andrew andrew 4096 Dec 6 16:48 .mailbox.mail.colleagues drwx------ 5 andrew andrew 4096 Dec 6 17:02 .mailbox.mail.colleagues.amy drwx------ 5 andrew andrew 4096 Dec 6 16:48 .mailbox.mail.colleagues.aslan drwx------ 2 andrew andrew 4096 Dec 6 16:31 cur -rw------- 1 andrew andrew 144 Dec 6 16:31 dovecot.index -rw------- 1 andrew andrew 10272 Dec 6 16:31 dovecot.index.cache -rw------- 1 andrew andrew 128 Dec 6 16:31 dovecot.index.log drwx------ 2 andrew andrew 4096 Dec 6 16:31 new drwx------ 5 andrew andrew 4096 Dec 6 16:53 .Sent Items -rw------- 1 andrew andrew 32 Dec 6 17:06 subscriptions drwx------ 2 andrew andrew 4096 Dec 6 16:31 tmp drwx------ 5 andrew andrew 4096 Dec 6 16:32 .Trash PROBLEM: When viewed in Thunderbird 3.1.6 or Outlook 2010: These nested dirs are seen: ..mailbox ....mail These nested dirs are NOT seen or can be subscribed: ......colleagues ........amy ........aslan OBSERVATIONS: When viewed in Apple Mail 4.3, all dirs are seen correctly. Thank you, I appreciate any and all replies, comments, questions, and suggestions. Jason

[Dovecot] Migrate dbox 1.2 virtual mail to 2.0
by Nick Rosier 08 Jan '11

08 Jan '11

Hi, I'm trying to migrate from Dovecot 1.2.16 to 2.0.7. Initially the mails were stored in Maildir format but I changed them to dbox using "fast Maildir migration" and some mails are still in the old maildir format. I'm trying to migrate these mails using dsync but dsync panics: % dsync -D -o mail_location=dbox:/var/spool/vmail/bunbun.be/nick mirror dbox:/var/spool/vmail2/bunbun.be/nick ...... dsync(vmail): Panic: file mail-storage.c: line 1351 (mailbox_save_set_guid): assertion failed: (guid == NULL || *guid != '\0') zsh: abort (core dumped) dsync -D -o mail_location=dbox:/var/spool/vmail/bunbun.be/nick mirror Any ideas?
