Good to know.  The other VERP I am experimenting with deals with a
number of emails I get that don't contain tell-tale signs (like -,_, or
.) but are otherwise one-shot emails.  At the moment, I am assuming that
if an email name contains more than 7 consecutive digits, the whole name
should be masked.  I have never seen a normal email account with that
many digits in a row.

# mask long numeric sequences
$user =~ s/.*[0-9]{7,}.*/#/g;

This may be less-useful in the wild, but seems to function well enough
for me.  The only drawback I can foresee is that this will probably mask
emails that are sent by cellphones/pagers etc. since those are often use
the phone number as the user name.

This and the other patch may very well need tweaking, so it would be
useful if people could look at their from_awl tables and see how things
are looking.
