Connected to smtp.mercurylink.net. Escape character is '^]'. helo it's me 220 localhost.localdomain ESMTP Sendmail 8.11.6/8.11.6; Sat, 28 Dec 2002 05:50:16 -0500 501 5.0.0 Invalid domain name The only thing I see wrong is their Sendmail. Their Sendmail server is miss-configured. It thinks it's name is localhost.localdoman. They should fix that. Otherwise, to accept mail from localhost.localdomain you would have to remove entry for localhost.localdomain in your helo_hostnames.
