When a mail is sent to LISTSERV is there any possibility to capture this
mail before LISTSERV is starting to distribute it to listowners?

What I would like to do is to detect when a person is sending a mail to
a list with a attachment.

My question is how can I detect that a mail is containing a attachment
and how can I remove it from the stream, change it and replace it in the
stream again?
