Hi
I am a web software developer by trade and this is my first foray into
configuring exim.
I am setting up a new server and the configuration seems to fail when
attempting to send email to other exim servers. (or other servers
doing the same verification)
The receiving exim server isn't able to verify my domain causing a
verification error, which is emailed back to me.
This message was created automatically by mail delivery software.
"A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es)
failed:
info@<TEST_DOMAIN>.com
SMTP error from remote mail server after RCPT
TO:<info@<TEST_DOMAIN>.com>:
host <TEST_DOMAIN>.com.au [203.130.28.14]: 550-Verification failed
for <testfrom@<NEW_SERVER>.com.au>
550-Unrouteable address
550 Sender verify failed
"
I understand the verification process according to:
http://www.exim.org/exim-html-3.20/doc/html/spec_45.html#SEC803
I need to fix my new server so it will send emails to servers that do
a full reverse lookup of the senders email address otherwise ill run
into all sorts of trouble sending email.
Any relevent commands or a setting i have overlooked whilst setting up
the server? (errors below) Or further reading i could do on this
subject?
(googling mostly results in info about turning off the verification at
the recipients server which is not relevant to my issue)
cheers
