AMTP
a replacement for SMTP

This is the home of the AMTP protocol. AMTP is being designed as a replacement for SMTP, with security features designed to reduce the impact of Unsolicited Bulk Email (UBE) and the cost of running mail servers.

Status

As of early 2007 there is a major hosting provider interested in providing resources for the development of AMTP begining late 2007 or early 2008. I will post more details here when I have them. I look forward to getting back on track after a few years of inactivity.

The fourth draft specification of AMTP (draft-weinman-amtp-03.txt) was published as an Internet Draft on 24 April 2004 (also available on this web site in Documents). The draft should be very close to what the final specification will look like.

Comments and discussion about the specification are still welcome. A mailing list has been established for this purpose. Please subscribe to the amtp-discuss list to participate. (Or use the form below.)

Soon, I will start writing a reference library in C, along with qmail-amtpd, a plug-in replacement for qmail-smtpd. I've chosen qmail for the first full implementation because I am already familiar with the code.

The reference code will be released as open source.

Mailing Lists
