Unfortunately there is plenty of mailing list manager software that
will disable your subscription if your mail is rejected enough
times. Mailman being a good example. I have been unsubbed from
mailman lists that have allowed viruses through, even with the
default mailman settings for boucne processing.
In a perfect world, no mailing lists distribute spam, viruses and
malware.
At the moment therefore while practicing reject after DATA I do find
it necessary to mark as spam and accept if it has Precedence: bulk
(or list or whatever), because otherwise my users complain and
"don't subscribe to poorly-managed lists then" is not an acceptable
answer for them.
