...except that the "+" (and everything between it and the "@") is *not*
actually part of the email address. To use your address as an example:
When Postfix receives an envelope for:
mouss+nob...@netoyen.net
It automatically strips the "+nobulk" and what it actually looks up in
the database is:
mo...@netoyen.net
I assume that the "+" magic is hard-coded in Postfix, so if I [knew what
I was doing, and] were to dig out the source code, it would be pretty
simple to change it to use "_" instead of "+". If I were to upgrade
this "hack" to something more respectable, I would:
1. Create a configurable parameter, rather than hard-coding it
2. Allow multiple characters (so I could still use "+" as well)
