ED> For sendmail add: ED> MASQUERADE_AS(`<your host/domain name here>') ED> To the sendmail.mc, then run 'm4 /etc/sendmail.mc > /etc/sendmail.cf' I added MASQUERADE_AS to my .mc file, regenerated the .cf file and restarted sendmail. My email is still being rejected with the same error "domain of sender address does not exist". Even with the MASQUERADE_AS, the server receiving my email still sees the actual domain name in use on my server which is bogus and not resolvable. Shouldn't MASQUERADE_AS tricked it so it looks like it came from somewhere else? -- Jake Colman Principia Partners LLC Phone: (201) 209-2467 Harborside Financial Center Fax: (201) 946-0320 902 Plaza Two E-mail: [EMAIL PROTECTED] Jersey City, NJ 07311 www.principiapartners.com -- redhat-list mailing list unsubscribe mailto:redhat-list-request@;redhat.com?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
