[Mimedefang] Heads up: Change in behvior for 2.43

[David F. Skoll]

Hi, all.

I just wanted to give everyone a heads-up on some behavior that will
change with the next release of MIMEDefang.

Currently, filter_relay is not called until after the MAIL command.
The next release will call filter_relay immediately after the remote
machine connects.  This has the following implications:

1) The $helo argument is not available; filter_relay will be called with
   only two arguments ($hostip and $hostname).

2) No Sendmail queue identifier will exist yet; therefore, no MIMEDefang
   working directory will exist either.  You will not be able to use
   file-based tricks to pass information from filter_relay to later
   functions.

I don't think this will have a huge impact on people; just move any
tests that require $helo and/or a Sendmail queue ID into filter_sender.

When 2.43 comes out, our reasons for this change will be clear.

Regards,

David.
