[Dovecot] Auto logging-out client
by Nicolás 28 Jul '12

28 Jul '12

Hi list! I'm writing because of an issue I'm having with my Postfix-Dovecot installation. Everything's working fine but when an IMAP client is idle for some time, Dovecot automatically logs it out. Jul 26 14:01:16 mail dovecot: imap(nicolas(a)devels.es): Disconnected: Logged out bytes=1271/7439 This entails errors when trying to send e-mails after this auto logout, such as: host devels.es[91.215.158.237] said: 550-Please turn on SMTP Authentication in your mail client, or login to the 550-IMAP/POP3 server before sending your message. Which result in a very annoying and continuous proccess of restarting my mail client. Is there a way to avoid this auto-logout, or at least configure the time after I want idle clients to auto-logout? Thank you very much! Nicolás

[Dovecot] Slightly OT - Winbind and remote authentication.
by Simon Brereton 28 Jul '12

28 Jul '12

Hi I was doing some research on setting up a samba server for my internal network (as an alternative to NAS). The setup looks easy enough, but then I got to thinking - I already have an internet host with an mysql DB that has usernames and passwords and it would be simpler all round to reuse that as the authentication server. That server is also running Dovecot, so I thought it might be simpler still to set up samba to authenticate using IMAP (the mysql server is not accessible on port 3306 anyway). A quick google resulted in a suggestion from Robert (who by now must be on every single list I'm on or rather vice-versa) about using winbind. I went off to the link he posted - http://wiki.dovecot.org/Authentication/Mechanisms/Winbind?highlight=%28winb… and the problem is that seems to indicate bind and dovecot are on the same server. So, this not being the samba list notwithstanding, is it possible to use a remote dovecot host as an authentication back-end on a local samba installation? Cheers Simon

[Dovecot] Problem overriding default quota limit
by RAUL JAREÑO MORAGO 28 Jul '12

28 Jul '12

Hi, We get user's quota limit from LDAP. It works fine when user has quota attribute in LDAP (this is when it's different from default quota). But when user doesn't have quota limit attribute Dovecot doesn't take default value defined in quota plugin and assign unlimit quota to user. Our configuration is similar to the example from wiki ( http://wiki2.dovecot.org/Quota/Configuration ). This is the plugin configuration _plugin {_ _ quota = maildir:User quota_ _ quota_rule = *:storage=1G_ _ .........._ _}_ And this is the recovered fields in LDAP search: _user_attrs = mailMessageStore=home,mailquotasize=quota_rule=*:bytes=%$_ It works if user has mailquotasize in its LDAP entry. But if it hasn't it Dovecot assign 0 instead of *:STORAGE=1G This is the log when LTMP deliver a mail to a user without mailquotasize attribute: _auth: Debug: master in: USER#0111#011eepp68#011service=lmtp#011lip=172.31.100.120#011lport=24#011rip=172.31.100.119#011rport=41452_ _auth: Debug: userdb-cache(eepp68,172.31.100.119): miss_ _auth: Debug: ldap(eepp68,172.31.100.119): user search: base=o=Junta de Castilla-La Mancha,c=ES scope=subtree filter=(uid=eepp68) fields=mailMessageStore,MAILQUOTASIZE_ _auth: Debug: ldap(eepp68,172.31.100.119): result: mailMessageStore=/buzones1/e/eepp68; MAILQUOTASIZE MISSING_ _auth: Debug: master out: USER#0111#011eepp68#011home=/buzones1/e/eepp68#011QUOTA_RULE=*:BYTES=_ _lmtp(8235): Debug: auth input: eepp68 home=/buzones1/e/eepp68 quota_rule=*:bytes=_ _lmtp(8235): Debug: Added userdb setting: plugin/quota_rule=*:bytes=_ _lmtp(8235, eepp68): Debug: Effective uid=11184, gid=2110, home=/buzones1/e/eepp68_ _lmtp(8235, eepp68): Debug: Quota root: name=User quota backend=maildir args=_ _lmtp(8235, eepp68): Debug: Quota rule: root=User quota mailbox=* bytes=0 messages=0_ I tried it with defining default_fields in userdb but I get the same result: _userdb {_ driver = ldap args = /etc/dovecot/dovecot-ldap-lmtp.conf.ext default_fields = quota_rule=*:bytes=1073741824 } If I don't recover mailquotasize (user_attrs = mailMessageStore=home) Dovecot assign default quota limit, so it works in this case: auth: Debug: master in: USER#0111#011eepp68#011service=lmtp#011lip=172.31.100.120#011lport=24#011rip=172.31.100.119#011rport=41427 auth: Debug: userdb-cache(eepp68,172.31.100.119): miss auth: Debug: ldap(eepp68,172.31.100.119): user search: base=o=Junta de Castilla-La Mancha,c=ES scope=subtree filter=(uid=eepp68) fields=mailMessageStore auth: Debug: ldap(eepp68,172.31.100.119): result: mailMessageStore=/buzones1/e/eepp68 auth: Debug: master out: USER#0111#011eepp68#011home=/buzones1/e/eepp68 lmtp(8198): Debug: auth input: eepp68 home=/buzones1/e/eepp68 lmtp(8198, eepp68): Debug: Effective uid=11184, gid=2110, home=/buzones1/e/eepp68 lmtp(8198, eepp68): Debug: Quota root: name=User quota backend=maildir args= lmtp(8198, eepp68): Debug: Quota rule: root=User quota mailbox=* bytes=1073741824 messages=0 Any idea about where is the problem?

Hi Daniel, The "userdb" ldap is in this section: protocol lmtp { mail_plugins = " quota sieve" userdb { args = /etc/dovecot/dovecot-ldap-lmtp.conf.ext driver = ldap } } And dovecot-ldap-lmtp.conf.ex contains this: hosts = xxx.xxx.es:389 dn = uid=xxxxx,o=xxxxxx,c=es dnpass = xxxxxxxxxxx ldap_version = 3 base = o=xxxxxxxxxxxx,c=ES user_attrs = mailMessageStore=home,mailquotasize=quota_rule=*:bytes=%$ user_filter = (uid=%u) A las Viernes, 27-07-2012 en 2:34 Daniel Parthey escribió: Hi Raul, Raul Jareño Morago wrote: > We get user's quota limit from LDAP.

Where is the "userdb" ldap in your doveconf -n output and where do you get the user information like quota from? > Any idea about where is the problem? The default is not taken since your LDAP query returns a quota_rule with an empty bytes= value when the mailquotasize entry is missing.

[Dovecot] emails are being marked as read auto-magically
by Joe Beaubien 28 Jul '12

28 Jul '12

Hi, I'm having a weird issue with dovecot 2.1.7 (using the latest thunderbird client). Something, I have emails that mark themselves as read on their own. No one touches them, and they get marked as read. I try to re-mark them as unread, but a few seconds later, they get marked as read again. The same problem happens in reverse (emails marks as unread become read). Has anyone ever experienced anything similar? I cannot see any warnings or errors in the dovecot logs, so I'm not sure if the problem is with thunderbird or with dovecot. However, I have never had this issue before switching from dovecot 1.0.X to dovecot 2.1.X. Unfortunately, we updated the thunderbird versions around the same time, so I feel like a dog chasing my tail on this issue. Any help would be appreciated. Regards, -Joe

I just tried configuring the submission port on postfix but the problem persists even sending by port 587. About what Harald said, I guess I initially missed the point of the problem, it was just my conclusion because that error happens always after the logout message appears, and SMTP authentication is set on my client, so I deduced the problem had something to do with the logout thing. The curious thing is it just happens with SMTP, not with POP3/IMAP protocols. Thanks again! Nicolás
