If you want your username to contain an '@' sign, you need to patch SASL to 
make this work, otherwise you'll get '(-13) NO User does not exist' errors or 
something (forget the message off the top of my head).  This is because SASL 
internally uses the '@' character to delimit the SASL realm from the 
username, which messes up your authentication scheme.

I've got this exact setup running at three sites in 2.1 and 2.2, with logins 
of the form 'username at domain1.com', 'username at domain2.com', etc.  It's a 
little bit of a hack, but it works for me.  I definitely recommend using 2.2 
-- it makes some of the other virtual domain stuff quite a bit easier/better.
