Blocking Double Extensions Except For . . .

I mean not mailscanner, just remarked the line with the dblext regex.
I had not much time to play around with it, and then it was left as is...
I guess I could've put an "allow *.pdf" regex to make it work, but didn't
bother.

Archiving only the infected (and/or spam) mails would be also a great
option as full mail archive is not much good except for some debugging.
