[lug] Postfix relay_host
Wed Jun 30 20:39:02 MDT 2004
How can I get my postfix to authenticate itself to a remote relay host?
When I send email from my home machine via comcast cable to
earthlink users, I get:
<someFried at earthlink.net>: host mx2.earthlink.net[220.127.116.11] said: 550
Dynamic IPs/open relays blocked. Contact <openrelay at abuse.earthlink.net>.
(in reply to MAIL FROM command)
No problem ... my ISP said I could relay through them.
So on my Postfix on Suse 9.1 I set:
relayhost = my.isp.com
But my ISP rejects all the email, since my Postfix is not sending
the userid / password. I've looked in the book, in the
online manual, and via google but find no answer ...
How do I configure Postfix to send a userid/password to the relay host?
