[Dovecot] Case sensitive oddity when mail delivered.
by dovecot＠corwyn.net 01 May '09

01 May '09

Currently running Postfix/Dovecot1.1.8 with mysql storing the user data and delivering to folders as determined by dovecot using dovecot's "deliver" as defined in postfix's master.cf Mail location is determined by mail_location = maildir:/var/spool/mail/%d/%n/Maildir If I have an account user1(a)example.com it works just fine. However, when mail is sent to USER1(a)EXAMPLE.COM it also delivers, but ends up creating a new file structure so I end up with /var/spool/mail/example.com/user1 (with lower case mail in it) and /var/spool/mail/EXAMPLE.COM/USER1 (with uppercase mail in it) which is decidedly not good. Looks to me like wherever %d and %n are pulled from is pulled out of the email, but not lower-cased. Any ideas where I would look to change this value before the email is delivered to the mailbox? Thx. rick Rick Steeves http://www.sinister.net "Life is like a sausage: The more you pack into it, the longer it gets"

[Dovecot] How to call a script when an E-Mail will moved in a folder?
by Luca Bertoncello 30 Apr '09

30 Apr '09

Hi, list! I use Dovecot 1.1.14 at work. It is configured to manage IMAP and IMAPs. Exim is the MTA of the Network. Of course, I installed SpamAssassin and ClamAV to check all incoming E-Mails. An, of course, some E-Mail marked as Spam are Ham and some E-Mail marked as Ham are Spam... To teach SpamAssassin I create for every user two folder: "DochSpam" (for Spam E-Mails not marked) and "FalscheSpam" (for Ham E-Mails marked as Spam). Every hour a cronjob search for E-Mails in these folders and call sa-learn to teach SpamAssassin. All run perfectly, but I'd like to modify this method and call automatically the script when the user move an E-Mail to DochSpam or FalscheSpam. I searched in Google, but I cannot found any useful link... How can I trigger an action (script calling) based on event (E-Mail will be moved to a folder) in Dovecot? Thanks for your help!

Re: [Dovecot] Unexplainable problem with POP3 quotas

> No, we don't. We use dovecot as POP/IMAP server, and let Postfix do the rest. How does Postfix deliver the mails? mailbox_command should be set to use deliver, not maildrop/procmail. > I see, but it seems like it is *another* solution rather than a > constraint. I just tested the quota-warning, with the dovecot-deliver-example. Exactly the same time as the mail exceeding the quota-percentage is delievered in the account, the quota-warning-message is generated and also delivered. > Anyway, we are neither sending an email nor using deliver. What we are > trying to do is to generate a message file that is injected into the > mailbox. But the script that should do that is never run by dovecot > :-( Try the injection using deliver, and use the "alternative script" from the wiki-page as quota_warning. I just tested it, works great. Also: when using dovecot-deliver, the maildir-indizes are being generated better and faster than with alternative MDAs. Best regards, Anton

[Dovecot] Unexplainable problem with POP3 quotas
by Marco Marongiu 30 Apr '09

30 Apr '09

Greetings * We are having a problem with POP3 quota warnings, and despite we dig into the documentation, mailing list archives, google... we didn't spot any light We are running a self-compiled dovecot 1.1.7. The user base is in a Postgres database. We'd like a quota warning message to be injected into the maildir at 80% and 95% of occupation reached. >From the logs, it looks like dovecot is correctly reading the quotas from the DB. Nevertheless, the warning message is never delivered. We tried many different configurations (e.g.: from using bytes instead of storage to change the quota configuration alltogether, I think we tried every single sensible, applicable solution that we could spot during our searches in the net). Currently, we have the following non-working one: root@mgo2-popimap-v01:/usr/local/dovecot/etc# ../sbin/dovecot -n # 1.1.7: /usr/local/dovecot_1.1.7/etc/dovecot.conf Warning: fd limit 1024 is lower than what Dovecot can use under full load (more than 16384).
