This is not entirely a webmin issue- but I would like to know where in webmin I should be fixing this problem.
If users log onto squirrelmail and send mail to AOL it gets rejected with a reverse DNS error (no reverse dns for myhost.mydomain.com - this is the FQDN of the server).
If users send mail through a pop mail client everything works fine (outgoing mail is usually carried through their ISP though).
Does anybody know how to get the reverse DNS working? Where am I supposed to change this info? No matter what I do, I keep getting that DNS error.
Thanks in advance for your help.
You want whoever manages your DNS records to add a "PTR" (reverse IN-ADDR) entry pointing to your mail server's IP. If you think they may have trouble doing that, ask them to make sure the PTR record matches your A (authoritative) record.
See RFC 1912 Section 2.1 for more.
