Debugging

Poste.io tries to log as much as possible. There are a few places where you can find valuable logs for debugging:

1. docker logs --tail=100 mailserver

   there should be all the information about starting and stopping services.

2. /your-data-dir/logs

   its essentially a copy of /var/log from the inner container. There are a few special directories in addition to the standard ones:
   • admin-app - web administration errors log
   • delivery - all email delivery logs should be logged there
   • dmarc - received DMARC reports
   • s6 - contains output from supervised services

3. /your-data-dir/domains/domain.com/username/.dovecot.sieve.log

   whenever the sieve script fails, the error should be logged in this file in the user's mailbox directory
