[Mimedefang] New errors following update to 2.85

[Philip Prindeville]

Hi,

I just updated my mail server from Fedora 33 to Fedora 34, and I noticed right away seeing these messages:

Nov 10 14:37:17 localhost mimedefang.pl[9141]: 1AALbHB8009400: relay: vger.kernel.org (23.128.96.18:56344 => 192.168.4.3:25)

Looking through the logs, this happens over and over, and only with the delivery of this one message.  Since it can't be delivered for some reason, I looked it up on MARC:

https://marc.info/?l=linux-netdev&m=163652637632433&w=2

Anyone have an idea what's going on?  Is there a timeout I need to increase?

Looking at:

Xmimedefang, S=unix:/var/spool/MIMEDefang/mimedefang.sock, F=T, T=S:2m;R:2m;E:10m

That looks like plenty...  

Other than that, everything seems to be working fine (well, I did have to change the $qid variable to filter_relay() and filter_helo() as that changed, but that was relatively minor).

BTW: who now owns the direction of development of MimeDefang?  Who is the designer-in-chief?

Thanks,

-Philip
