[Dovecot] Qpopper migration?
by Steve Goodman (lists) 09 Nov '06

09 Nov '06

Hello, As this is my first post to the list, first and foremost I'd like to thank Timo for writing great software; we've successfully moved to Dovecot for over 10,000 users from UW-IMAP and get great performance. On our overloaded staff POP3/IMAP server, we are looking at replacing qpopper+uw-imapd with dovecot, as an interim before moving them to the main Unix mailstore. The system is primarily POP3, with a small number of heavy IMAP users causing the system grief. There are a large number of POP3 users who leave messages on the server. What I want to ensure doesn't happen is that they are forced to download them again. Do I need to add anything specific in the pop3_uidl_format or am I barking up the wrong tree? Kind Regards, Steve

[Dovecot] SSL-read error in logfile
by Egbert Jan van den Bussche 08 Nov '06

08 Nov '06

Now most things seem to work (rc12 on Mandriva 2007.0), I've been looking more thoroughly at the syslog file. I see a 'syscall failed' at the end of a normal timed poll from the client. I wonder what it means. Sorry for the layout, it is messed up by the cut and paste. I have created the selfsigned cert and key in the /etc/ssl/dovecot/[certs,private] directories.

[Dovecot] Quota without dovecot LDA
by Riccardo Bini 08 Nov '06

08 Nov '06

Hi all, I use dovecot with maildir quota plugin + qmail + vpopmail but not dovecot LDA. My dovecot configuration: default_mail_env=maildir:~/Maildir:INDEX=/var/cache/dovecot/indexes/%h/%u:CONTROL=/var/cache/dovecot/control/%h If CONTROL env is set the maildirsize file is stored in /var/cache/dovecot/control/ but I use vpopmail as LDA. It's possible to add a setting in dovecot.conf to specify if dovecot LDA is active?? This is my pseudo-patch: src/plugins/quota/quota-maildir.c static const char *maildirsize_get_path(struct mail_storage *storage) { if (lda_enable) { return t_strconcat(mail_storage_get_mailbox_control_dir(storage, ""), } else { bool is_file; return t_strconcat(mail_storage_get_mailbox_path(storage, "", &is_file), "/"MAILDIRSIZE_FILENAME, NULL); } } dovecot.conf: lda_enable = no Ciao Rick

[Dovecot] How to give system and virtual users their own mail_location?
by Egbert Jan 08 Nov '06

08 Nov '06

Hi all. Now hopefully as a new thread because I still have this question. Apologies to Geert and Timo for my misbehaviour...(repling to the list and changing the subject). I hace Dovecot rc12 working on Mandriva 2007.0 now for system accounts and virtual accounts both imap and imaps can be used. Th problem now is that I cannot use both types of user at the same time. The 'mail_location = ' strings are very different: Real system users have their Maildir in /home/%u/Maildir/ but virtual users have their maildir in /home/virtual/%d/%n/. How can tell dovecot to use the first for /etc/passwd clients and second for mysql authenticated clients? Just adding two private namespaces does not work. That is for ONE user having more mailbox locations, isn't it? Thanks for any hints! Egbert Jan (NL)

I spent most of today adding new content to the Wiki and cleaning up the existing content. The front page is now also reorganized, but there are several links in it to pages which are still missing. Please write them. :)

[Dovecot] L4 probes..
by Jorgen Lundman 08 Nov '06

08 Nov '06

Probably a special case here, but everytime the L4 probes the port, a line as added to the log. This gets a bit noisy. If a random IP connects, I'd want to see it, but maybe it would be nice to have the option to silence the log entry from certain hosts. For now I patch it locally, but without any .conf finesse. For example: Nov 8 10:55:24 corppop01 dovecot: [ID 107833 mail.info] pop3-login: Disconnected: rip=172.16.253.5, lip=172.16.253.128, TLS handshake Nov 8 10:58:00 corppop01 dovecot: [ID 107833 mail.info] pop3-login: Aborted login: rip=172.16.253.5, lip=172.16.253.128 -- Jorgen Lundman | <lundman(a)lundman.net> Unix Administrator | +81 (0)3 -5456-2687 ext 1017 (work) Shibuya-ku, Tokyo | +81 (0)90-5578-8500 (cell) Japan | +81 (0)3 -3375-1767 (home)

[Dovecot] dovecot lda works with maildir++ but does not enforce the quota?
by Antonio Casado Rodríguez 08 Nov '06

08 Nov '06

Hi all, I use Dovecot lda. Is there the possibility that dovecot lda works with maildir++ but does not enforce the quota? I have dovecot 1.0rc12, postfix, RedHat Enterprise Linux ES 4.0 Update 4. IMAP client Thunderbird 1.5.0.7 Only namespace: namespace private { separator = / inbox = yes prefix = location = maildir:~/Maildir/ } Thanks a lot.

[Dovecot] deliver feature request (filter)
by Neal Becker 08 Nov '06

08 Nov '06

I'm using maildrop for delivery, because I want to filter through spamassassin before delivery. Maildrop makes that trivial. It seems deliver can pipe (one way) to a command, but what is needed is to pipe: deliver -> spamd -> deliver which is what the maildrop xfilter does.

[Dovecot] Duplicate header extension keywords
by Rainer Ophoven 07 Nov '06

07 Nov '06

I'm running dovecot supporting imaps and pop3s in a small home-office environment on a Linux-box, kernel 2.4.33, with postfix-2.3.4, amavisd-new and spamassassin. I use Thunderbird as mail-client on Windows XP. ever since upgrading to RC10 I every now and then find these error messages in doveocot.log: Error: IMAP(rainer): Corrupted index file /home/rainer/Maildir/.software.Dovecot/dovecot.index: Duplicate header extension keywords and close by: Error: IMAP(rainer): Fixed index file /home/rainer/Maildir/.software.Dovecot/dovecot.index: first_recent_uid_lowwater 1952 -> 1951 Misconfiguration or where is the problem? -- in diesem Sinne, Rainer
