There are many more problems that list readers do not see.  I delete the
address from the list only when the problem is persistent.
The major problem happens when messages take a few days to bounce, and
the bounce does not follow standards.  In that case there are dozens of
messages in the remote queue, and they all appears to be replies by a
valid list subscriber.

A surprising amount of 64 bit software (certainly not limited to the
Opteron) is still not mature enough for general purpose use.  It still
requires more development and testing to get to the stability level
required for real deployment.  And it's not the "64 bit" nature of the
software, since we did have reasonable maturity on the Alpha years ago.
