I'm trying to setup postfix on my own server to be my own personal sneakemail service. For those of you unfamiliar, sneakemail allows you to generate email addresses that are more or less disposable, so when you sign up for a service, you provide your sneakemail address and it gets forwarded to your normal account. If you do give unique addresses for all the services you use then you'll be able to identify the sources of spam and if you so desire, cut off that address.
I've looked at some of the filtering options for postfix but I'm not sure which option I should use. I already have postfix set up to allow emails only for my @domain but I would like to be able to set up a filter to decide who these emails should be delivered to, and optionally be able to just ignore the email, or bounce it back as undeliverable, or pass it on to the correct recipient.
What specific documentation can guide me to accomplishing this?
