I've noticed a larger number of files in the queue than usual. Many are are
being retried a number of times. A look in the log showed a couple of error
messages popping up quite often:
1. 451 <[EMAIL PROTECTED]>...Sender domain must resolve
2. 451 4.1.8 <[EMAIL PROTECTED]>...Domain of sender address
[EMAIL PROTECTED] does not resolve
3. 450 4.4.3 For input: <[EMAIL PROTECTED]>... policy analysis
reports DNS error with your source domain.
We've recently moved the Imail server behind a NAT, and have had some
trouble with DNS and forwarding, so this may have caused the problem.
However, email for the most part seems to be flowing, with the execption of
mailing lists. It appears from a quick scan of the log that only lists are
having these difficulties.
Thanks for the help
Josh
