yup, but not the actual e-mail adress but the 'sender information' which now is
"Forum (name-of-forum) forum"
admin@name-of-forum.com
Board is in Polish language and word "forum" is at the first place, in contrary to English languge (e.g. "forum samochodowe - "car forums", "forum nastolatk?w" - "teen forum").
Hope you get what I mean.
edit: i've found similar thread at vbulletin.com but it hasn't been explained
