Is it possible to set the recipient delimiter to more than one
character so that, for example user+foo OR user_foo would both be
mapped to 'user' with the address extension 'foo'?

I know it seems weird, but I have a lot of established '+' addresses
on my server taht people use to sort their mail into mailboxes via
procmail, and that works great, except...

Well, there's an awful lot of clueless gits out there running company
websites that insist that '+' is illegal in an email address. Yes, I
know they're wrong (thus the 'clueless git' comment) and you know
they're wrong, but the fact of the matter is there's no way to get
coke.com or cnet.com, for example, to fix their idiocy.

I've checked all the various email addresses on the machine and none
use '_', though quite a lot use '-' (all the mailman aliases, for
example), although I've also considered = or #, though I suspect the
same nincompoops who disallow '+' will likely disallow = and # as well.

So, possible? Or is there some other way around this where I could,
for example, rewrite incoming user_foo email to direct to user+foo
internally?
