Well that really depends on a couple of factors, one of them being the
contents of your virtualdomains file.
Anyway, to answer your question: only the . is special.
This is because DJB was worried about malicious persons mailing to
blah-../../.. and stuff like that. In fixing that, he figured out the /
might actually come in handy: you could have a .qmail-/ dir with all your
virtual stuff in that dir. Therefore, the . was made special.
