I'm using postfix on ubuntu 12.04 server, with help from https://help.ubuntu.com/community/Postfix
after setting up sasl as above guide, I tried sendmail - and sendmail just hangs.
here's what I've done:
# cat mail.mail To: <myid>@gmail.com Subject: test mail From: root@<myserver.com> a test mail # sendmail -vt mail.mail (a blank line displayed forever and i have to Ctrl+C out of it)
though I can send mail via telnet.
#telnet localhost 25 EHLO <myserver.com> MAIL FROM: root@<myserver.com> RCPT TO: <myid>@gmail.com DATA test mail . (mail sent to <myid>@gmail.com, thrown directly to junks though)
