[Dovecot] Session IDs
by Timo Sirainen 28 Apr '12

28 Apr '12

v2.1.2 added support for "session IDs", which is a 9 year unique identifier for that specific IMAP/POP3 connection. Initially I thought it would only be useful for tracking connections going through Dovecot proxies to backends (the session ID is forwarded), but then I thought it could be useful for everyone if auth process also logs the session ID. So I thought for v2.1.6 I'd change the defaults: a) Failed login: Apr 28 17:37:23 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=XtG7KL6+jQB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=42125 resp=<hidden> Apr 28 17:37:23 auth: Debug: passwd-file(foo,127.0.0.1,<XtG7KL6+jQB/AAAB>): lookup: user=foo file=/usr/local/etc/passwd.imap Apr 28 17:37:23 auth: Info: passwd-file(foo,127.0.0.1,<XtG7KL6+jQB/AAAB>): unknown user Apr 28 17:37:25 auth: Debug: client out: FAIL 1 user=foo Apr 28 17:37:50 imap-login: Info: Aborted login (auth failed, 1 attempts in 27 secs): user=<foo>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, session=<XtG7KL6+jQB/AAAB> b) Successful login: Apr 28 17:38:27 auth: Debug: client in: AUTH 2 PLAIN service=imap secured session=rNuHLL6+jgB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=42126 resp=<hidden> Apr 28 17:38:27 auth: Debug: passwd-file(tss,127.0.0.1,<rNuHLL6+jgB/AAAB>): lookup: user=tss file=/usr/local/etc/passwd.imap Apr 28 17:38:27 auth: Debug: client out: OK 2 user=tss Apr 28 17:38:27 auth: Debug: master in: REQUEST 1375993857 14321 2 0f2f78deedcb7e38a278cf79819360c5 Apr 28 17:38:27 auth: Debug: passwd-file(tss,127.0.0.1,<rNuHLL6+jgB/AAAB>): lookup: user=tss file=/usr/local/etc/passwd.imap Apr 28 17:38:27 auth: Debug: master out: USER 1375993857 tss uid=1000 gid=1000 home=/home/tss Apr 28 17:38:27 imap-login: Info: Login: user=<tss>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=14338, secured, session=<rNuHLL6+jgB/AAAB> .. Apr 28 17:47:15 imap(tss,<rNuHLL6+jgB/AAAB>): Info: Disconnected: Logged out in=8 out=369 The last line requires a modified mail_log_prefix, I wasn't planning on changing its default. I'm mainly wondering: 1) Does this change break someone's auth log line parsing? 2) Does the auth prefix look prettier with or without <> around session id? :) 3) Anything else I should do about this now that I'm changing it anyway?

I can confirm that the issues are gone when using pigeonhole-0.3.0 I thought the sievec crashes might re-appear, but this isn't the case. Thank you Robert.

[Dovecot] OT but E-Mail related. save a copy off all mail as eml
by Götz Reinicke 26 Apr '12

26 Apr '12

Hi, I'm sorry to bug you with an not directly dovecot related question, but this is for me right now the place with the best mailsystem admins I know. I'm asked if there is a way to save a copy of all mail we send trough our sendmail server (Red Hat EL 5.x) in and out as an .eml file for further processing by a DMS system. The files should be saved on some network share. Any suggestion are welcome and thanks.
