# Miscellaneous suggestions # Miscellaneous suggestions
To use fail2ban for your mail server, create `/etc/fail2ban/jail.d/mail.local`:
```ini
[postfix]
enabled = true
logpath = /var/log/postfix.log
[dovecot]
enabled = true
logpath = /var/log/dovecot.log
[sieve]
enabled = true
logpath = /var/log/dovecot.log
```
These are the log file locations we configured above, but you can set them to the syslog if you didn't give Postfix and
Dovecot their own log files.
