 Posted: Tue Apr 25, 2006 6:50 pm Post subject: postfix - relay outbound via ISP SMTP server w/AUTH [SOLVED] |
 |
|
I searched the forums, but none of the answers for others solved my problem.
I'm running a postfix server and am sending directly to destination MX hosts. I've run into issues with hosts denying my mail, so I'd like to relay through my ISP and the ISP requires login.
I got the HOST/ID/PASS from my ISP. I can send using this information directly via Thunderbird, but getting postfix to do it is resulting in "relaying denied" messages. From this info, I believe postfix is just not auth'ing the ISP SMTP server.
I've followed several guides on this forum and the internet, and all declare the same solution. However, it does not work for me. I'm lost and would appreciate some help in debugging or solutions.

your /etc/postfix/sasl_passwd is in the format as:
| Code: | | [smtp.lbdsl.net] <id>:<pass> |
note [] around smtp.lbdsl.net

yes, I found that syntax in the docs from postfix. the "[ ]" is supposed to mean that it won't check for MX records. I originally tried using this entry without the "[ ]", but since that didn't work either...
here's where I got the syntax:

edit you master.cf, locate the smtp line and put a -v so it read:
| Code: | | smtp unix - - n - - smtp -v |
send an email and watch your mail log for clue.

Sweet!
thanks, langthang. I didn't know how to do that before. From watching the verbose logs, I discovered that the SMTP server was actually an alias (my bad for not noticing earlier). The ISP's FAQ didn't take into account people running a mail server. I put the real host in the sasl_passwd file and postmap'd it, and everthing worked!
As a side note, my master.cf smtp line actually references "smtpd" instead of "smtp" as the command (last arg).
ie. | Code: |
smtp inet n - n - - smtpd
|
I don't care too much because it works, but it's odd. It came that way from the package, so I'm not going to worry about it.
thanks again. Yet another fast turnaround from the Gentoo forums - I love 'em!
