First, I apologise for using English but my Spanish and Catalan are 
really not good enough at the moment.. (currently read only ;) as a bit 
of background I have been writing perl for money since 2001 (in the UK), 
but since September I have been working for HP in Sant Cugat although 
not doing much programming there unfortunately.

Anyway, when using sendmail -t you have to be very careful especially if 
accepting input externally as an attacker could potentially slip some 
\n's in there followed by their own data thereby you unintentionally 
become a spam relay.

Hope this is useful,
