I act as a "spamcheck"-relay for a couple of servers but I get this
error message for one server when I'm trying to relay a message to it:
Mar 17 10:28:07 myrelay postfix/smtp: 1358410A329:
to=<>, relay=mail.domain.se[81.228.XXX.XXX]:25, delay=0.4,
delays=0.08/0.01/0.27/0.05, dsn=5.7.1, status=bounced (host
mail.domain.se[81.228.XXX.XXX] said: 550 5.7.1 <>...
Relaying denied. Proper authentication required. (in reply to RCPT TO
And I get this on the server I'm trying to send to (it runs Sendmail):
Mar 17 10:28:22 gateway sendmail: o2H9SMYZ026927:
relay=smtp3.myrelay.com[194.218.XXX.XXX], reject=550 5.7.1
<>... Relaying denied. Proper authentication required.
If I try telnet to the mailserver from my relay-server I get this:
myrelay:~/# telnet mail.domain.se 25
Connected to mail.domain.se.
Escape character is '^]'.
220 domain.se ESMTP Wed, 17 Mar 2010 10:40:35 +0100
250-domain.se Hello smtp3.myrelay.com[194.218.XX.XX], pleased to meet you
250-AUTH PLAIN LOGIN
I am updating my servers and "myrelay" is the new one, the old one runs
Sendmail and can relay just fine to it without any "Relaying denied.
Proper authentication required."
I have no idea what the problem is here and was hoping you could help
me? Can it be something with my sasl-setup on my new server? But
mail.domain.se doesn't show STARTTLS when I telnet to it..
Thanks for any help!
