[TriLUG] dotted username?

[Brian Henning]

Hi Folks,
  I'm setting up an in-house e-mail server to apply some e-mail filtering
and spam management.  There are currently some usernames and/or aliases at
our current (3rd-party) e-mail server contain dots in the username (such as
joe.blow[at]strutmasters.com).  Apparently such a username is not a valid
UNIX username, so how do I create a mailbox that has a dot in its name?  I'd
like to avoid changing anyone's e-mail address at all costs, really.
I'm running sendmail on FC2.

Thanks in advance!

Cheers,
~Brian
