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 i better now postfix, but this message i have seen often, if a server doesn't have an in-addr.arpa entry. In this case, the mailserver rejects also... HTH Roger
