SMTPerr is a tool designed to extract error messages from "bounces" - the emails received from "Mailer Daemon" and so on, after a mailout. If your mailing list is large, you may get several hundred - or more - bounces each time you send a newsletter. Processing these manually is a challenge. SMTPerr reads the bounces and summarises each error in a single file. This file can then be viewed and changes made to the source mailing list accordingly.

SMTPerr supports errors from a multitude of mailers, including Exchange, exim, GroupWise, qmail, postfix, and AppleMail. It also includes a generic MIME-based routine to recover the error from MIME data, if needed.
