[Mailman-Users] get a (limitted) copy of messages discarded due to spam filters

[karrageorgiou giannis]

dear mailman people,

I have a public list and try to trim the inevitable spam with 
rules that look reasonable but I am not completely sure they 
won't backfire for legit mails

(e.g. consider sender names as fictitious when having 
20+ consecutive letters)

I was thinking of receiving a copy of the discarded
messages for sometime, until I am sure the rule is
fair, and manually forward as myself a mistakenly 
dropped text

(preferably get the text/plain part only; still drop them 
automatically (attachments and all), as most are expected 
to be spam, not deserving to store and hold for approval)

(notice that mailman is used as testbed. The regexrule (when 
verified) would go to postix drop ruleset, so mailman won't 
even be bothered)

is this possible with mailman? I didn't see something
relevant in the web-interface (but I might have missed
it; sorry to bother you if so)

thanks beforehand for any clue
