[Mailman-Users] munging email address in archives

[maurizio codogno]

I was told by a subscriber of a list I manage that there are some 
worms/viruses which are able to parse addresses in the form 
"user at domain dot domain", like those used in the archives by mailman.
Do you know if there is some provision in Mailman 2.2 to let the list
admin choose a munging expression for addresses? I do not know Python
at all, but I hope it would not be so difficult, especially if there 
is already a function which performs the munging!

TIA, .mau.
