Hi,

Thanks for the suggestions.

I think that this is one of the cases, where half of the users would
like to have this functionality (because they trust their
downtstream users to klick the right things) and the other half could
not work with it (because they do not trust their downstream users and
having a untrustworthy bayes-db is worse than not having one at all.

In general I'm not too sure that Bayes filtering is too effective in an
environment with one classification body for many users.

I think that this would be problematic for many users, because the
subject contains quite sensitive information (and is not necessary for
routing mail as opposed to from/to mail-addresses) - so if we add
something like that it would need to be optional!

(and comment that you'd like to see that as well)

It seems nobody has had the time to pick up that topic yet, but we
could provide some help and feedback if somebody wants to implement it.
see PVE's developer documentation for an overview of our workflow [1].

This would be quite difficult to implement, because PMG does not have
an explicit list of mailboxes it delivers mails to.
If you use LDAP for your mailboxes you can do this already with a
fitting ruleset (put those users who wish to get the mails into one
group and put their mail into the quarantaine, tag the mails only and
deliver them directly for others)

The Spamquarantine is meant as a self-service portal for individual
mailboxes and depending on the setup can contain very much information,
(and sensitive information, which should only be looked at in limited
cases) - I would use the statistics or logs to get an overview about
false positives.
