Package: exim4-daemon-heavy
Version: 4.50-4
Severity: normal

I would expect a MTA to simply queue mail that it tries to send when the
network is down (or packet loss is high).  However, exim4 bounces it,
with an unhelpful "Unrouteable address" message.  (These are messages
being sent off-site).  The exim4 mainlog doesn't have any other useful
information, either.

Even stranger: sometimes, it will log things like:

R=dnslookup T=remote_smtp defer (110): Connection timed out

and behave as desired.

I can't figure out why it doesn't do that all the time.

Any hints would be appreciated.

Ouch. I didn't even know that this option exists.

May I ask for the URL to the spam recipe? I need to point its author
towards the ACL verify clauses which to a much better job in achieving
what the dns_again_means_nonexist option is mean to do in the
anti-spam recipe.

Doing so.

No problem, it was not a big waste.
