Using Ham Passwords For Filtering

Systems using “ham” passwords ask unrecognized senders to include in their mail messages a password that distinguishes the message as a ham (good) message. Quiet often the email address and the ham password would be described on a web page while the “ham” would be included in the “subject” line of an email address. Ham passwords combined with filtering systems, counter the risk that a filtering system will accidentally identify a ham message as a spam message.

Some mail services allow a user to append a +tag qualifier to their e-mail address (e.g., jimuser+tag@example.com). The text of tag can be used to apply filtering. The text of the tag can also be used to help a user figure out which organization "leaked" the user's email address to a spammer. However, some mail servers refuse to send mail to a user on another system because the local part of the address contains the (+) sign. Disposable email addresses are supported by several email services including Runbox(plus and hyphen),Google Mail (plus),Yahoo Mail Plus (hyphen) and Fastmail(plus).
