Why not use a filter to "sort" replies? What's the invariant that I would sort on? The sender and the subject may change, say if the sender passes my address on to someone else. However my address can't if the mail is to reach me.It depends. For this list, it's : ^X-BeenThere: evolution lists ximian comThat won't work if someone on this list puts my address into his contact and later mails me. That also won't work to identify and block which business sold my address to spammers. It won't even work to sort mail from good businesses who change their address slightly. This is particularly relevant since there are apparent subtleties to the filtering that I haven't figured out yet.
Ah. I use postfix+mailfilter+imap/maildir, and just use Evo filters for outbound mail.
The unique property of user+subject is that (if I implement a few other things also) is that if someone deletes or changes the tag, then he can't mail me. I.e., anonymity is not possible. Phishing me becomes harder. If I give paypal an address of wrf+paypal038487 host, then mail to any other address pretending to be from paypal is fake. Another way to do this is to buy your own domain and give everyone a different address, i.e., UNIQUE MYDOMAIN COM This is useful since some braindead web forms refuse to accept certain valid addresses, e.g., with plusses. However using this also requires editing 'from' lines (or creating lots of accounts).
You make good point.
