Hi Joris,
The "matched a filter rule" is the principal reason for holding
messages for moderation. Please don't become anxious about the
situation -- one of the reasons we have become concerned about
the situation is that people whose messages get held up do tend
to become worried about it. This is unnecessary -- they, and you,
are not really doing anything wrong!
As I understand it, the filter rules are set by the ethz.ch admins,
and even Martin does not seem to know, in detail, what they are.
Also, it is likely that the filters "learn", and they may well
be "learning" from a lot of other emails received at eth.ch which
have nothing to do with R-help but which are true spam -- then the
headers of such messages could be folded into "Bayes spam scores"
which can trigger "matched a filter rule".
As far as R-help is concerned, the situation seems to be that
gmail.com and nabble.com are important triggers (though there
are plenty of others). Lots of email addresses which do not have
the username ending in digits are trapped in this way.
In round figures, proportions I have logged myself amongst the
messages held because they "matched a filter rule" are:
non-gmail, non-nabble: 30%
non-gmail, nabble : 25%
gmail, non-nabble: 32%
gmail, nabble : 13%
gmail : 45%
nabble: 52%
The true nature of this situation is still unclear!
Ted.
