Thanks, Kjetil!
Your tip lead me to the right path.
After a few deductions I found out that the smtp ports are closed, except for
the xxx.xxx.55.1 which is the MX I´m using as a smarthost (luckly he didn´t
disabled this function there).
I´m not sure how efficient is this measure, if there´s a wi-fi network filtered
simply by MAC. Anyone could hack into it and spam the world through this
smarthost quite easily.
