hi,
i just saw an entry, where it seems, that sendmail could not resolve a reverse-zone (or i misread...) so check:
- are all your servers entered with a and mx entries in your forward-zone files of your dns-server
- are all your servers entered with a and mx entries in your reverse-zone files of your dns-server
A and MX entries are only for forward zones (absolutely *never* use a CNAME, always use an A). The reverse zone should contain a PTR record that matches.
Cheers,
