Urgent: MailScanner apparently stopped processing...

So is the problem fixed by upgrading MailScanner to 4.21, or do I upgrade
postfix to 2.0.9 (latest), or do I need to upgrade both?

Thanks for the insight and response.

> - Postfix support now won't abandon a message because it could not get

> - Postfix will always pick up IP address of locally-generated mail. -
> Postfix detects hash directory depth more cleanly.
> - Postfix handles queue files which are still being written.
> - Postfix bug fixed when processing messages with no body.
