[Dovecot] Wish: change default log_timestamp
by Steffen Kaiser 07 May '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'd suggest to change the default value of log_timestamp to something with complete date and time. Currently the string is missing the year. Maybe, %F (ISO date) would fit best.

[Dovecot] FETCH for mailbox INBOX UID 5003 got too little data: 5369 vs 38919
by Adam McDougall 07 May '08

07 May '08

This happened a while back, I was running 1.1rc3 up until today so I have no idea if it would have an effect. Sorry if its something that has been fixed. The error below was repeated many many times, I deleted the index so the user would stop getting disconnected (although I didn't hear any complaints). I have not seen this happen repeatedly in this manner to any other user yet.

[Dovecot] dovecot + exim + verify recipient / reject bad recipient at SMTP time
by Peter Hudec 07 May '08

07 May '08

hello, I'm quite new to dovecot. My instalation is working good Debian Etch - exim: 4.63-17 - dovecot: 1.0.rc15 I'm using virtual user setup, with LDA delivery method. There is no database backend at this time. Is there any way to configure exim to reject non-existing user /asking dovecot lda/ at SMTP time. The standard exim configuration in ACL section do not work: --- cut --- require message = e-mail address is not valid ($local_part@$domain / $recipient_verify_failure) domains = +virtual_domains verify = recipient --- cut --- Please, have any work working example ? This setup work good witch cyrus-imap and LMTP. best regards Peter Hudec

[Dovecot] Manual thread breaking from Thunderbird
by Christian Jaeger 07 May '08

07 May '08

Hello I'm looking for a way to manually break threads apart when independent threads are mixed up, mostly by users which aren't aware that they should not be replying to existing threads when starting a new one. Since Thunderbird afaik does the threading itself, it would require a solution that actually changes the In-Reply-To header (and maybe also that other (non-standard?) header which is being sent by the M$ clients). For me modifying the actual emails on disk would be fine, i.e. renaming the In-Reply-To header to Old-In-Reply-To and such. (I'd actually *prefer* a solution that modifies the server side store, as opposed to one which keeps that info on the client side only like mutt seems to be doing.) Is there a way to do this already? Seems like a task for a dovecot plugin--or for the xexec plugin and an external perl script or some such? For triggering the renaming, a hacky solution could be to misuse labels (e.g. marking a message starred and "Later" and "Important" at the same time would trigger the modification and remove the labels). When implementing such a thing: maybe also offer a way to modify subjects (for those cases where people are using short meaningless and recurring subjects--to both help breaking up the ensuing threading as well as giving them a useful replacement), maybe as an IMAP extension or such (to be used by Thunderbird plugins (?), or by web apps). (I can code in C and Perl, but don't generally have much time.) Christian.

[Dovecot] Question about Maildir automatic cleanup.
by José Ildefonso Camargo Tolosa 07 May '08

07 May '08

Hi! I want to automatically delete old messages from one user's Maildir, and I was thinking on running something like this: find /home/user/Maildir/cur/ /home/user/Maildir/new/ -daystart -mtime +15 -delete but I'm not sure if by deleting messages "manually" I will break the dovecot.index* files. What do you think? Thanks! Ildefonso. ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo! Mobile.

[Dovecot] 1.07 to 1.0.13 mail_extra_groups
by Mark Sapiro 07 May '08

07 May '08

I have just upgraded from 1.0.7 to 1.0.13. I read the comments in the example .conf file and it seemed what I needed to enable dotlock access to mailboxes in /var/spool/mail (writable by 'mail' group) was "mail_privileged_group = mail" so I removed the "mail_extra_groups = mail" that I had in 1.0.7 and added "mail_privileged_group = mail", but I got errors like the following: May 6 12:48:54 sbh16 dovecot: POP3(xxx): file_lock_dotlock() failed with mbox file /var/spool/mail/xxx: Permission denied May 6 12:48:54 sbh16 dovecot: POP3(xxx): Couldn't open INBOX: Internal error occurred. Refer to server log for more information. [2008-05-06 12:48:54] May 6 12:48:54 sbh16 dovecot: POP3(xxx): Couldn't open INBOX top=0/0, retr=0/0, del=0/0, size=0 May 6 12:48:54 sbh16 dovecot: pop3-login: Login: user=<xxx>, method=PLAIN, rip=72.52.113.36, lip=72.52.113.36, secured I then put "mail_extra_groups = mail" back in the configuration. This seems to have the effect of setting both "mail_privileged_group = mail" and "mail_access_groups = mail" as well as issuing "Warning: mail_extra_groups setting was often used insecurely so it is now deprecated, use mail_access_groups or mail_privileged_group instead" when dovecot is started. So my question is what do I need. I thought it would be just "mail_privileged_group = mail", but that doesn't work. Do I need both "mail_privileged_group = mail" and "mail_access_groups = mail" or just "mail_access_groups = mail". Also, are the comments describing these in the example .conf file correct, or are they reversed. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

I checked the logs of dovecot and the following is noticed dovecot: May 06 11:12:25 Info: imap-login: Login: user=<ath>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured dovecot: May 06 11:12:25 Info: IMAP(ath): Disconnected: Logged out there are lots of messages for a single login .

[Dovecot] deliver custom maildir creation
by Steve Roemen 06 May '08

06 May '08

/ I'm testing a new setup of postfix using deliver to put the messages into the user's maildir, and am curious if there is a way to make deliver create custom maildirs when it delivers to a valid user without a maildir? Right now it only creates the inbox, I'd like it to create the .sent/ .Trash/ and .SPAM dirs. Is this possible? Thanks -------------------------------------- / /Steve Roemen// /
