If you are using sendmail, you should be able to used
'plussed' addresses. The local (username) part of the
address to the left of the plus is the base.  Sendmail
will look for .forward files in that user's home directory
in the form of .forward+xxxx where xxxx is the part after
the plus. If it doesn't find a match, it looks again
for a standard .forward and then performs a normal delivery.
That means you should be able to use an address like
faxmail+phone-number at yourdomain.com and have faxmail
alias parse out an arbitrary phone number.  I think
procmail already gets the plused part as an argument
during delivery so if you run the command out of .procmailrc
you'd already have it - otherwise it can be difficult
to interpret mail headers since you can't tell if a
certain delivery is for a To:, or CC: or something not
even in the headers.
