[Dovecot] debug user's message retrieval
by Костырев Александр Алекс еевич 10 Sep '11

10 Sep '11

Hi there! Is there any method to log user's activity with pop3 service? I'll try to explain situation: In maillog I saw that my dovecot lmtp saved four letters in user's mailbox. After a while I got a call from that user saying that he received nothing. Is there any method to log that that user RETR every single letter, maybe with full names of letter's id or something like that?

What webmail is this? It's Horde webmail. Webmail does pop. Yahoo and Gmail do it too. When I first set up the server, it did it on first login - obviously because the server had changed but it's doing it once a week now (and in fact, it did it twice today). It's not fatal, no one will die. It is a PITA though. Simon

[Dovecot] Mails repopping
by Simon Brereton 09 Sep '11

09 Sep '11

HI I don't know if this is a dovecot issue or a client one. But as Dovecot is the most recent change, I'll start here. I have a server that's been running Courier for about 6 years and in all that time I think I've only ever had 1 issues where an entire mail box was repopped by a webmail client. However, since moving to a new server and dovecot 4 weeks ago, I've now had the webmail client repop this account 4 times (there are about 230 mails in the account). Is there a setting I need to tighten to prevent/remedy this? I have no idea if it's happening on other accounts, but this is one that I see. The format is maildir. There has been no changes to the webmail client. Thanks. Simon

[Dovecot] Quota fs (ignore mount)

> I set "quota: fs:INBOX:noenforcing:mount=/var/spool/mail", but receive: "fs quota add storage dir = /home/pit/mail"... > Why ? Well .. I'm not entirely sure if the current behavior is good or not, but what you need to do to get it working is to add two quota roots. One for /home/pit/mail (i.e. without specifying mount=) and another for the INBOX's /var/spool/mail.

[Dovecot] copy and empty userA folder1, append to /var/mail/userB
by mathog 08 Sep '11

08 Sep '11

Dovecot 2.0.13 on a 64 bit linux. We have an archiver account on one machine. Most mailing lists that handles go directly to it and everything is fine. However, there is one campus list that will only send to real people. So for that one I subscribed. When one of these messages comes in, which is 1-2x per week, I copy it to an export folder and then manually run a script which does: cat ~me/mail/export >>/var/mail/archiver echo "" > ~me/mail/export That worked fine on our last system, but dovecot doesn't like it. It leaves the imap indices for the export mailbox in an inconsistent state, so that roundcube (through dovecot) refuses to drop messages into it. The error message roundcube emits is: ServerError: Mailbox isn't a valid mbox file. Presumably the second half is from dovecot. I need a supported way to go about this, so that the next time one comes in I can copy to that folder again. The export mailbox is always completely emptied. It would suffice if there was some way to force dovecot to create "empty"" .imap/export: dovecot.index.cache dovecot.index.log files. Note this isn't a problem for the archiver itself, since it doesn't have any imap indexed files. Suggestions? Thank you, David Mathog mathog(a)caltech.edu Manager, Sequence Analysis Facility, Biology Division, Caltech
