I'm able to use Postfix to send mail to e.g. GMail accounts: Apr 26 22:41:14 blog postfix/pickup[14939]: 49ACD8081A: uid=1000 from=<ejain> Apr 26 22:41:14 blog postfix/cleanup[14969]: 49ACD8081A: message-id=<20100426224114.49acd80...@...> Apr 26 22:41:14 blog postfix/qmgr[4627]: 49ACD8081A: from=<ej...@...>, size=352, nrcpt=1 (queue active) Apr 26 22:41:15 blog postfix/smtp[14972]: 49ACD8081A: to=<[email protected]>, relay=gmail-smtp-in.l.google.com[209.85.217.51]:25, delay=1.1, delays=0.02/0.01/0.31/0.71, dsn=2.0.0, status=sent (250 2.0.0 OK 1272321675 19si6283624gxk.13) Apr 26 22:41:15 blog postfix/qmgr[4627]: 49ACD8081A: removed
But when I log in as a different user on the same machine, Google's mail server no longer accepts mail (the reverse DNS lookup test appears to fail): Apr 26 22:38:58 blog postfix/pickup[14939]: E5ECD8081A: uid=33 from=<www-data> Apr 26 22:38:58 blog postfix/cleanup[14951]: E5ECD8081A: message-id=<20100426223858.e5ecd80...@...> Apr 26 22:38:58 blog postfix/qmgr[4627]: E5ECD8081A: from=<www-d...@...>, size=355, nrcpt=1 (queue active) Apr 26 22:39:30 blog postfix/smtp[14953]: E5ECD8081A: to=<[email protected]>, relay=gmail-smtp-in.l.google.com[74.125.67.27]:25, delay=31, delays=0.03/0.03/0.34/31, dsn=5.7.1, status=bounced (host gmail-smtp-in.l.google.com[74.125.67.27] said: 550-5.7.1 [...] The IP you're using to send mail is not authorized 550-5.7.1 to send email directly to our servers.
