> One of my back burner projects was to write a mail forwarder which did not store messages. I wrote one of these years ago, as a front-end to my Exchange server. At the time Exchange had this thing where it ALWAYS accepted messages as long as the domain part was an accepted domain, and then it would do a fuzzy match on the mailbox names and dump the mail anywhere it felt matched. So I had to have this SMTP front-end forwarder to weed out mis-addressed mail... which I eventually added SpamAssassin to as well. It ran for over 10 years without issue. What I never solved/wrote was the TLS stuff, as it always seemed to complicated to code from scratch.
