LMTP, PAM session and home directory autocreation
by Ivars Strazdins 11 Apr '19

11 Apr '19

Hi, mail is delivered by Dovecot's LMTP locally and I need user's home directory to be created if it doesn't exist yet. There is a setting in Dovecot's configuration, "session=yes", in /etc/Dovecot/conf.d/auth-system.conf.ext, which should do that. passdb { driver = pam args = session=yes dovecot } But I think it does not work in my setup because I do not see any PAM log entry for Dovecot in system log when this error happens: Apr 9 13:01:55 mailhost dovecot: lmtp(2935): Connect from local Apr 9 13:01:55 mailhost dovecot: lmtp(2935, testuser): Error: User initialization failed: Namespace '': mkdir(/home/testuser/Maildir) failed: Permission denied (euid=174000327(testuser) egid=174000327(testuser ) missing +w perm: /home, dir owned by 0:0 mode=0755) Apr 9 13:01:55 mailhost dovecot: lmtp(2935): Disconnect from local: Successful quit The error above seems expected, because it is not LMTP agent's job to create user's home directory but pam_oddjob_mkhomedir.so module should do that. Right? And there are common PAM log entries for every user session: Apr 9 13:24:42 mailhost auth: pam_sss(dovecot:auth): authentication success; logname= uid=0 euid=0 tty=dovecot ruser=validuser rhost=::1 user= validuser Apr 9 13:24:42 mailhost auth: pam_unix(dovecot:session): session opened for user validuser by (uid=0) Apr 9 13:24:42 mailhost auth: pam_unix(dovecot:session): session closed for user validuser How to debug this problem and find out why Dovecot does not open PAM session or - if I am wrong and it does, then what else is going wrong? Home directory autocreation is configured with command "authconfig --enablemkhomedir --update" and it works if user logs into system via shell or webmail. I tried to enable "mail_debug" in Dovecot's settings, but it did not give me any more information on PAM session. Running on Centos 7.6, with Dovecot 2.2.36. It looks like a common mistake or issue, because I am not alone: http://tinyurl.com/y6kjhsnw Thank you very much in advance for your time.

High availability of Dovecot
by luckydog xf 11 Apr '19

11 Apr '19

Hi, list, I'm going to deploy postfix + dovecot + CephFS( as Mail Storage). Basically I want to use two servers for them, which is kind of HA. My idea is that using keepalived or Pacemaker to host a VIP, which could fail over the other server once one is down. And I'll use Haproxy or Nginx to schedule connections to one of those server based on source IP( Session stickiness), I'll use VIP as DNS record.etc, is my plan doable? I know MX could be server ones with different priority. But I think it brings along shortage that DNS couldn't know Email server is up or down, it just returns results to MUA, right? Thanks for any suggestions and ideas. -

Marc, There is a strategy loosely referred to as "choose your battles well" :-) Let the others bother with their own problems. If you can, hack the server and dump the 500GB - you'll be using resources transferring the 500GB as the other server receives it. Two servers wasting resources because you think you are punishing an offender!

Passord change problem. (INTERNAL)
by Arvid.Eikas＠telenor.com 11 Apr '19

Hi, We have a strange problem with login after password change. We need to kill the auth_worker processes to activate the new password. It doesn't work with SIGHUP on pid, it doesn't help to run "doveadm auth cache flush". It runs flush xx but the new password still doesn't work. Are there any suggestions for how this can be resolved? Our release is 2.3.5. Arvid

Lua Push Notification Plugin
by Robust Coding 11 Apr '19

11 Apr '19

Hi Admin, I hope you consider reading and addressing my concern promptly. For the past few days I've been setting up a VPS with cPanel and WHM pre-installed on Bluehost. I want to enable push notification plugin in Dovecot2.3.5. I tried OX and Lua plugins and got errors. For using OX plugin: push_notification_driver = ox:url=http://staging.mydomain.com/mail-notify/v1 user_from_metadata And got this error on runtime: *Error: push-notification-ox: Skipped because unable to get attribute: Mailbox attributes not enabled* When using Lua: mail_plugins = $mail_plugins mail_lua notify push_notification push_notification_luaplugin { push_notification_driver = lua:file=/path/to/lua/push.lua} And got this order: *Plugin 'push_notification_lua' not found from directory /usr/lib64/dovecot* I think I'm missing something here but I can't figure it out. Please HELP! Sincerely, John Lopena -- *"Become a programmer - Lose your brain's virginity"*
