Email Logs
All email logs are stored persistently and can be accessed directly from the host system. There is no need to enter a container to diagnose mail flow issues, authentication failures, or filtering results.
Data and Log Locations
The root directory for email persistence and logs on the host operating system is:
All active log files are consolidated within the following subdirectory:
Service Specific Logs
Postfix (MTA)
Use these logs to troubleshoot outbound delivery, inbound SMTP reception, and relay issues.
/var/local/LxRoot/email/data/logs/postfix/postfix.logLogs are rotated daily and gzipped. Older logs follow the pattern: postfix.log.yyyymmdd-hhmm.gz
POP/IMAP (Dovecot)
Use these logs to troubleshoot client connection issues, mailbox authentication, and IMAP folder errors.
/var/local/LxRoot/email/data/logs/dovecot/dovecot.logOlder logs are compressed in the format: dovecot_[unixtimestamp].tar.gz
Spam Filter (Rspamd)
Use these logs to determine why specific messages were flagged as spam or rejected by the filter.
/var/local/LxRoot/email/data/logs/rspamd/rspamd.log
To watch mail flow in real-time, you can use the tail command on the host:
tail -f /var/local/LxRoot/email/data/logs/postfix/postfix.log
