You literally telnet on P:25 to their SMTP server and type the commands by hand. If you still get the error - something is wrong on their end.
You live and learn! I have tried doing this for mailgate01.barclays.co.uk and mailgate02.barclays.co.uk and 90% of the time both immediately fail with:
421 4.0.0 mailgate02.barclays.co.uk Server error
So the error is at their end... ?
But, I did managed to connect successfully a few times, and got as far as:
RCPT TO: <MY [EMAIL PROTECTED]>
Christopher,
I'd telnet to their server on port 25 and do the following:
EHLO your.mailserver.hostname
(you should get a string of 250- response messages)
MAIL FROM: <[EMAIL PROTECTED]>
(you should see another 250- response, if you get an error here, their mail server doesn't like something about your email address. more than likely your domain. more than likely your domain doesn't resolve properly)
RCPT TO: <the.email.address.you'[EMAIL PROTECTED]>
if at this point it returns a 421 error, the problem is definitely on their side, and it appears to be a problem with the recipient.
if you get another 250- response then type:
DATA
(you should get a 354- response, type in anything and then follow it by a single . on its own line)
if HERE you get the error, then it could be related to anti-virus or anti-spam software configuration on their end, or other general configuration problems on their end. It could be related to sender or recipient depending on how their mail server is configured.
Whereon I get "domain invalid" response. But I haven't seen any such failures in the logs, so I suspect that it generally doesn't get this far... Unless I don't have the log level set correctly - is there a recommended level for debugging? Currently:
define(`confLOG_LEVEL', `8')dnl define(`confMILTER_LOG_LEVEL', `8')dnl
for debugging you might want to crank it up to 14
hope this helps
