This is wrong; you should be using an IP address inside the domain- literal form (square brackets). You should try to fix whatever the problem with your DNS is, instead. "dig -t mx gmail.com" should return valid results.... > However, there is still a problem, when I > try to send an e-mail, /var/log/maillog says: > > Aug 23 23:18:08 arches sm-mta[1049]: k7O3I7K2001049: > from=<nink@XXXXXXXX.xxx>, size=397, class=0, nrcpts=1, > msgid=<44ED1A6F.1090009@XXXXXXXX.xxx>, proto=ESMTP, daemon=IPv6, > relay=localhost [IPv6:::1] > > Aug 23 23:18:16 arches sm-mta[1051]: STARTTLS=client, > relay=gmail-smtp.l.google.com., version=TLSv1/SSLv3, verify=FAIL, > cipher=DES-CBC3-SHA, bits=168/168 > > Aug 23 23:18:16 arches sm-mta[1051]: k7O3I7K2001049: > to=<nicholasink@gmail.com>, ctladdr=<nink@XXXXXXXX.xxx> (1007/0), > delay=00:00:08, xdelay=00:00:08, mailer=smtp, pri=30397, > relay=gmail-smtp.l.google.com.

Yes, on their side. gmail.com isn't going to relay random email without you authenticating first, probably; look into configuring SMTP AUTH on your side, or talk with <postmaster@gmail.com> about what their requirements are to permit you to relay via their mail servers. However, normally people configure their machines to relay email via the SMTP server(s) which your ISP provides, as they are generally configured to trust their client networks without requiring SMTP AUTH and thus are easier to use... -- -Chuck
