Zimbra Problem

[clarky2k3]

We are currently having problems with our zimbra email server where-by all of a sudden cannot send emails out coming back with an error rejected address [email protected]. Can get emails in no bother! I have telnet into our mail server port 25 and performed a helo. This is the output

 

220 mail.coqueths.internal ESMTP Postfix
helo
501 Syntax: HELO hostname

 

Any ideas

if you read the log file, it might say why the mail was rejected

 

tail  /var/log/zimbra.log

Have you made it onto a blocklist ?

 

Does internal mail work ?

 

If you are relaying through another server is it rejecting your mails.

 

Is mail still coming in ?

 

try

 

tail -f "your log file" as you are sending a message.
