Reproducible: Always Steps to Reproduce:
the draft is now http://www.ietf.org/internet-drafts/draft-weinman-amtp-02.txt
draft-weinman-amtp-02.txt was succeeded by draft-weinman-amtp-03.txt, which expired in October 2004. Currently, the main web site for AMTP is <http://amtp.bw.org/>. The home page on this site is dated April 2004, and promises a proof-of-concept Perl implementation "by the end of May." There's no sign of any more recent activity on the site, and a google search didn't turn up anything recent either. Overall, the project looks pretty dead. hcihw ,
The attempt appears to be rather dead, and there does not appear to a major server or client-side implementation. -> WONTFIX.
