But there is nothing at all which makes it inherently wrong. MAYBE it is
not possible in limited cases (like all numbers for an AOL local part) but
as a general case there is nothing inherently bogus about an address
matching the regular expression [0-9]+[a-zA-Z]+[0-9]+.*@.* and in fact I
have multiple regular correspondents with such addresses.

IOW: what you recognize as 'obvious spam' isn't.  It would be a very bad
rule for me to use. Maybe you would want to use it.

It would certainly be nice for the SIMS router to have a full RE parser to
allow more complex rules The fact that there are standard RE libraries
available as easily portable standard C open source under a BSD-ish
license makes that something that Stalker might be persuaded to do without
too much effort.
