[Dovecot] ID command bug & patch
by Mike Abbott 09 Mar '11

09 Mar '11

When I set imap_id_log=* in dovecot-2.0.11 and a client sends, say, tag id ("a" "b" "c" "d") then dovecot logs: ID sent: a=b, b=c, c=d The following patch makes it log instead: ID sent: a=b, c=d --- a/dovecot/src/lib-imap/imap-id.c (revision 113366) +++ b/dovecot/src/lib-imap/imap-id.c (working copy) @@ -164,6 +164,7 @@ str_append_c(reply, '='); str_append(reply, str_sanitize(value, 80)); } + args++; } return str_len(reply) == 0 ? NULL : str_c(reply); }

Frank Bonnet put forth on 3/8/2011 2:07 PM: > disk space I need to gain a bit space > before migrate to the new server After you shut down the Dovecot daemons in preparation for copying the mailbox files to the new sever, simply delete all the index directories. That will free up a huge amount of space. The indexes will be automatically rebuilt when users log into the new server. -- Stan > Le 08/03/2011 17:39, Stan Hoeppner a écrit : >> Frank Bonnet put forth on 3/8/2011 9:54 AM: >>> Hello >>> >>> Is it possible to use compressed mailboxes ( MBOX format ) >>> with dovecot using a plugin ? >> >> What is your motivation? >>

You could ask on Postfix list to get the warning removed.. wietse dont wants to change anything until it is not documented http://archives.neohapsis.com/archives/postfix/2011-03/0356.html may be the developers should talk directly to each other, i dont like to get forwarded to each other list to ask for reliability of features...

If you're not doing local sync with TB and you have GLODA disabled, TB is going to show you exactly what's in your Dovecot mailbox. If the message doesn't disappear from your TB view sometime after deleting it on your smartphone, then I'd say it's very likely that Dovecot didn't receive the delete and/or expunge command from the phone. Check your Dovecot logs and see what the phone is actually sending, or not sending. Both of you mentioned problems specifically WRT smartphones. It's likely the IMAP implementation in these phones is simply buggy, or your network coverage is spotty. I don't use a smartphone so I can't really say. What smartphone are you each using? -- Stan

[Dovecot] logging sent messages
by Hajo Locke 08 Mar '11

Hello, i use plugin mail_log to see more activities like copy/delete/expunge caused by imap-users. unfortunately there is no log-line when a mail was sent and the copy was uploaded to "Sent-Folder". Isn't it a common imap-copy operation requested by client? How to log this? Thanks, Hajo

[Dovecot] Curious problem: Plaintext authentication disallowed on non-secure (SSL/TLS) [read: all] connections.
by Andrew Lewis 08 Mar '11

08 Mar '11

Hello all, I've set up a new instance of dovecot 2.0.9 to use as a POP3/IMAP proxy. On trying to login I am told '-ERR Plaintext authentication disallowed on non-secure (SSL/TLS) connections'. I have set 'disable_plaintext_auth = no' (see output of doveconf attached). More curious still is that *this happens for SSL connections too*. Something seems very wrong here.

[Dovecot] POP3 error
by Thierry de Montaudry 08 Mar '11

08 Mar '11

Hi, Since we upgraded to 2.0.9 (from 1.10 stock CentOS release), we are getting some errors with pop3. When the machines get busy, now and then it start with the following: > Mar 7 11:19:51 xxx dovecot: pop3-login: Error: net_connect_unix(pop3) failed: Resource temporarily unavailable And it generates hundreds of those before the machines dies, with the web server getting stuck as well on imap sessions, even though there is no imap error messages. I tried to lookup in the source where this is generated, but couldn't find it. Is it some resource limit on the machine? Please see bellow the dovecot -n output.
