Debugging

Poste.io try to log as much as possible. There are couple places where you can find valuable logs when debugging:

1. docker logs --tail=100 mailserver

   there should be all information about starting and stopping services.

2. /your-data-dir/logs

   its essentially copy of /var/log from inner container. There are couple special directories besides standard ones:
   • admin-app - web administration errors log
   • delivery - all logs from email delivery 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 sieve script fails there should be error logged to this file under user mailbox directory
