Where do I find the mail logs?
/var/log/maillog (darned near everything else)
How do I 'watch" the logs?
See the page on watching the mail logs.
How do I delete logs on a periodic basis?
Those in /var/log/mail are easy to deal with, as old logs are dropped into YYYY/MM/DD directories. Nuke them as desired. The syslog mail.* is similarly easy, as it's rotated daily and a weeks worth are kept. Edit /etc/newsyslog.conf to alter settings.
