If your inbound mailer handles plussed addresses (sendmail does by
default), it would seem like a logical enhancement to add +destaddress
(with the @ encoded) to the From: and envelope from address on these
messages so you can parse it back out of any bounce or response
regardless of whether or not it includes any content that you sent. 
Sensible list mailers will group addresses so the MTA can deliver them
efficiently with multiple recipients per host, but those monthly
reminders that contain your password have to be constructed and send
individually anyway.
