Procmail to Sieve translation
by Gerhard Wiesinger 28 Jun '14

28 Jun '14

Hello, I'm trying to move from procmail to dovecot sieve. I found the translation script at http://www.dovecot.org/tools/procmail2sieve.pl It works well except the following use cases: * ^From:.*myemail@mydomain.com.* | formail -I"X-Priority: 2 (high)" -I"X-mydomain-com-seen: yes" | $SENDMAIL -oi \ myemail(a)mydomain2.com \ myemail(a)mydomain3.com :0c * ^From:.*myemail@mydomain.com.* ! +1123456789(a)mysmsprovider.com :0c * ^(To|Cc|Bcc):.*myemail@mydomain.com.* ! myemail(a)mydomain2.com myemail(a)mydomain3.com Is there a possibility to support these use cases (can be done manually)? How does forwarding to another domain work at the deliver process? :copy seems not to be supported, right? Thank you. Ciao, Gerhard

Dovecot virtual and SASL with Postfix
by Jerry 28 Jun '14

28 Jun '14

This is my first attempt to set up virtual users and sasl with Postfix. Can I use a regular password file in this format: user:{plain}password user2:{plain}password2 or do I need to use a different format? I have been trying to find an example of a virtual user SASL file, but without any luck. I suck at Googling too. All of the mail will be delivered to :/var/mail/vmail/<domain>/<user> -- Jerry

mixing Maildir and mdbox
by gustavo panizzo <gfa> 28 Jun '14

28 Jun '14

Hello i'm in the process to architect a new email system. i plan to use dovecot 2.2.9 (debian's wheezy). i would like to use maildir for 2 folders on each account (spam and no-spam) and the rest of the folders stored on mdbox. this should be opaque to my users. the reason for this, is i want to be able to train my anti-spam tools, but they read maildir or mbox, they don't read mdbox or dbox. but i want the other folders as mdbox (performance, backups, alternate storage) is there any way?, i prefer if is configurable in advance for all accounts but i could live with something that is done after account is created thanks! PD: please keep me CC'ed as i'm not subscribed to the list -- 1AE0 322E B8F7 4717 BDEA BF1D 44BB 1BA7 9F6C 6333

Re: question on lmtp logged message

Just did some more scripting and got a total of 1413 distinct emails (distinct queueids) that suffered from this 'message was expunged' problem on the 36 hours i got the problems. As noted before, not even a single one of these 1413 were nrcpt=1. Problems were from nrcpt=2 or greater. So, whatever this is, it really seems to NOT affect single recipient messages. As you suspected, on those 1413 the very first recipient ALWAYS got a status=sent from dovecot/lmtp. "Message was expunged" never happened on the very first recipient delivery. About the first user (the first delivered message) checking the message right after delivery, i tried to confirm that by the logs. To make things a little easier, i used nrcpt=2 and nrcpt=3 situations, just to avoid posting lots of logs here.

Despite of that, 2nd recipient got the message successfully delivered. But we have also a delay=22 ... maybe lmtp instance had already opened the message BEFORE it was erased by the 1st user ? this delay is high, i know that and, usually, server do NOT suffer from this delays on deliveries. Anyway, during this problem period, queues were pretty large and, thus, load was very high, which i think explains this unusual delays. With these two cases, it really seems that this is somehow related to: - lmtp as delivery agent - multiple recipient messages - first (or previous users in fact) checked and deleted the message before all the recipients got the message delivery About the two parameters, maildir_copy_with_hardlinks and pop3_fast_size_lookups, i'll try to change them one at a time and try to reproduce the problems. Fact is i only had the problem with both set to yes and problems were completly vanished when both were set to no. -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it
