Of course, remail clients, e.g., Jack B. Nymble v2, have this capability.

Typically, the remailer keeps a log of the MD5 hash for each incoming message for some length of time; one week is common. The remailer will then delete messages that hash to a value already in the log. This reduces the effectiveness of replay attacks. These replay caches also permit remailer users to send messages through redundant chains with the same final remailer. Redundant chains increase reliability, while the message log prevents duplicates. (Remailers are notoriously unreliable; the test statistics that tell users which remailers are reliable usually show at least half of the active remailers to be losing messages.) > How does one find all the mail-to-news gateways?

Someone concerned enough about privacy to use an anonymous remailer might want the client on the local machine, perhaps compiled locally from inspected source code. Or are you certain that major music companies won't put up their own Web page to "help" others distribute pirated material? > Tcl code can directly interface to a mailer without a browser.

Almost all, if not all, remailers respond to a message that has "remailer-key" (without the quotes, of course) as its subject. They reply with a message containing the PGP and Mixmaster keys. (Remailers also respond to "remailer-help", "remailer-conf", and "remailer-stats".) Some remailer operators automate the process of retrieving keys.
