[ale] Why ALE hated my email and how I fixed it

[Jim Kinney]

?!?!? GNU software has BUGS !?!?!?

I suspect it's more an issue of DNS caching or the lookup process on
the server itself. I don't find anything about mailman requires A
record for smtp anywhere.

However I did find that it's a flaw in bind:
https://lists.isc.org/pipermail/bind-users/2009-January/074885.html

I will keep checking on this. The ALE servers is NOT running a DNS
service but it is running a caching service for internal use (seemed
like a polite thing to do since we are getting the server and
bandwidth provided on someone else's dime). So that flaw may be the
root cause.
