I make use of detail addressing to filter my mail. For example: RCPT TO Delivery location ------- ----------------- lyndon /var/mail/lyndon lyndon+imap ${HOME}/Mail/imap/... (MH) lyndon+sysalert /var/mail/lyndon + an X11 on-screen alert lists+freebsd-current LMTP to the lists/freebsd/current folder on the local IMAP server Not all of the filtering I require can be done based on the MAIL FROM. I have to have access to the RCPT TO address that triggered the delivery in order to do some of this filtering. While you can usually determine the MAIL FROM by examining the Return-Path: header in the message, you cannot determine the RCPT TO address by looking inside of the RFC2822 message headers. This eliminates POP and IMAP for "delivery" of this mail. Also, I *do* have delivery to multiple user accounts on my laptop. Polling for these multiple "users" from another mail server would be inefficient and wasteful of resources. For the times that I'm directly connected to my regular LAN at my regular IP address, mail flows in via SMTP directly to the laptop. I don't go polling any IMAP or POP servers to collect my mail. When I'm not connected to the usual network, I don't want to (nor should I have to) change how I retrieve my mail. And I don't have to. When I'm on the road (and direct SMTP delivery fails because I'm not reachable at the usual IP address), my mail is delivered to the MX backup host. The MTA there queues my mail up for UUCP delivery. When I get the chance to get connected, be it via IP or direct dialup to the backup MX server, I fire up a UUCP session which pulls down incoming mail for the laptop (and also sends any queued outbound mail), all the while preserving the sender and recipient *envelope* addresses, which are critical to my filtering needs. All without requiring *any* changes in how I handle my email. IMAP and POP are not message transport protocols. If you're using them as such you need to take a close look at your email environment. --lyndon >What about all the people who hoarded tonnes of spam in their bunkers? I hoard spam on my hard drive.
