I'm speechless. postfix/smtp[1311]: 1222F440344: to=<[email protected]>, relay=example.com[74.220.219.67]:25, delay=13, delays=0.05/0.01/1.5/12, dsn=2.0.0, status=sent (250 OK id=1QD0Vp-0005U8-IE) After 2 days listening non-sense at Bluehost support your clear and concise help proves once again invaluable. I don't post much on this list but I read it when I get the time. Let me take the opportunity to say that I really admire your work. I have yet to find another project (free, paid or whatever) that offers the same level of quality in execution, documentation and support. > > /etc/postfix/main.cf: > transport_maps = hash:/etc/postfix/transport > > /etc/postfix/transport: > # Specify the recipient's domain name, not the MTA hostname. > bluehost.com really_busted: > > Commands: > > # postmap hash:/etc/postfix/transport > # postfix reload > > Documentation: > > http://www.postfix.org/postconf.5.html#smtp_rcpt_timeout > http://www.postfix.org/transport.5.html > http://www.postfix.org/master.5.html > > Wietse -- Arthur Titeica PharmEc Software
