Hi Monks,

I would like your collective wisdom on how best to impliment a SPAM filter for outbound SPAM.

Looking at the conventional solutions everything is based on preventing incoming spam and not designed to stop sending it :( It may be that I have missed something blatently obvious.

I have a website that have a large number of email forms that are used to send requests from the public to clients. Recently we have experienced a number of spammers copy and pasting into the forms.

Putting in a graphical code image would prevent bots using the forms but not stop people from copy and pasting. To make things more complex it is perfectly valid for a person to ask the same question of multiple clients.

My initial thoughts were along the lines of implimenting a whitelist and quarantining everything else. However with my hundreds of emails going through the system this will be manually intensive to manage. Now my thoughts have moved to a delayed mailing system that quarantines all mail except whitelisted addresses. If no more mails are recieved within a period it releases them otherwise it flags it to administrators.

Now back to the real question.

Can any of the CPAN modules such as Mail::SpamAssassin be used to flag potential outbound spam before it becomes an email?

Thanks
