I use this a lot when signing up on online forms, but sometimes their validation process won't allow a "+" in the email address. If you have your own domain you can setup say "philip.domain.com" and make it so that *anything* sent to that domain actually goes to email@example.com.
Once you've setup the domain and the mx records in DNS, under sendmail you'd add the following line to /etc/mail/local-host-names
and to /etc/mail/virtusertable:
Then run make in that directory and you can now send to literally any address @philip.comain.com.
Just another way to do the same thing really.
