Lists

I 've a filter that sends all mail to viviane(_at_)geral(_dot_)net to
viviane(_at_)newsite(_dot_)com(_dot_)br

But, viviane(_at_)geral(_dot_)net is on a list os messages, and the TO is the 
address
of the list, so, the filter doesn't work.

Obs!! In the header, there is the following info, maybe we can use it to
filter:

Mail-For: <viviane(_at_)geral(_dot_)net>

How can I correct that?

Thanks!
