Hello, Postfix normally filters mail using a pipeline like
smtp --> content_filter --> smtpd but it lacks the lmtpd that would also enable lmtp --> content_filter --> lmtpd Why is that useful? I've seen a few questions posted about forking mail. This is usually a bad idea for incoming mail, but when it is locally generated there can be reasons :- For reasons of privacy and email management, I am trying to mask the sender's address into an externally visible alias, but which alias makes sense would depend on the recipient. No problem when there's one recipient, but a problem when there are many; it ends up forking the email into groups of recipients, dependent on which address they may get to see. When forking the email by sending it to multiple output processes, the most dreadful half-way failure conditions can occur, which degrade the transactional quality level of email handling. With LMTP in and out however, a content_filter can easily return which of the recipients have gotten their email sent, and which did not. Postfix would then return a report based on what it got replied into the initiating lmtp process. Would this be considered a bad idea, or just a new idea? Thanks, Rick van Rein
