Hi all,

I am still struggling with this issue.

I scraped my previous configuration and started from beginning.

Thanks to Aki Tuomi and his suggestion I changed the users in my configurations from vmail --> root and that helped.

Now I have a working replication but with some problems and strange behavior.

Replication works only when I manually execute a command:

"doveadm sync -A tcp:secundary:server:12345"

Automatic fast and full sync do not work:

doveadm replicator status "*"
username priority fast sync full sync success sync failed
zdokman none 01:46:14 01:46:14 01:46:14 -

doveadm replicator status

Queued 'sync' requests 0
Queued 'high' requests 0
Queued 'low' requests 0
Queued 'failed' requests 0
Queued 'full resync' requests 0
Waiting 'failed' requests 0
Total number of known users 1

doveadm replicator dsync-status
username type status
- Not connected

maillog has no error entries.

my conf files are attached.

I don't understand why is this happening and how to fix it, any help is much appreciated.

Best regards,

Hi,
Thank you for your reply Aki.
I changed my configuration and substituted vmail user with root user.

Now I have no error massages in maillog but replication is not working, mails are not visible on second server.

Your problem is that you are running service doveadm as vmail, but you are using real uids. You need to start doveadm server as root to be able to switch into the correct target user.

Hi all,

I am in need of some help.

Straggling to make something work, trying to configure postfix and dovecote imap server with dovecote replication.

Can’t figure out what is wrong with my configuration.

Replication is working only for vmail user account, I am getting this error on my secondary server for all other users…

dovecot: doveadm: Fatal: setgid(4015(zdokman) from userdb lookup) failed with euid=5000(vmail), gid=5000(vmail), egid=5000(vmail): Operation not permitted (This binary should probably be called with process group set to 4015(zdokman) instead of 5000(vmail))

primary server reports this error:

dovecot: doveadm(zdokman): Error: doveadm server disconnected before handshake: EOF

dovecot: doveadm(zdokman): Error: sync: Disconnected from remote: EOF

doveadm sync *

doveadm(root): Fatal: execvp(Maildir) failed: Permission denied

dsync-local(root): Error: read(remote) failed: EOF (version not received)

I am attaching my dovecot.conf main.cf and master.cf.

I think my problem is with permissions but I can figure out how to workaround it.

Best regards
