Hi, We get intermitend deliver-errors when we have activated the mail_log plugin. The installed version is dovecot-2.0-beta5. Below, the error we get:

it's a bug or a misconfiguration?

As long as you don't provide doveconf -n output, I'm sure it's a configuration issue. ;-)

Hm, I'm not using namespaces, ACLs or NFS. The mail_log plugin is working fine so far. Tested with dovecot-lda and imap. Also for an account with userdb filed 'mail=maildir:~/Maildir'. This are my settings; doveconf -n -m mail -x:

Your dovecot-deliver.log and dovecot-deliver-errors.log are writable for the user with uid 96? Any SELinux warnings in your logs? Can update to the latest code from the hg repo and try again?

Regards, Pascal

Yes, the vmail user (uid 96) has permitions to write on dovecot-deliver.log and dovecot-deliver-errors.log. The mail_login plugin is working normally, but at sporadic periods dump this kind of errors and refuse to deliver the mail. I don't have the SELinux enabled in this machine, and don't have any warnings/errors in other log files.

Now, I haven't used the hg repository sources, but I could try with the last version...

Thanks, Xavier
