Is it something you want > running on a production mail server? Eric, the first three paragraphs of section 1 of RFC 2476 explain this. In a nutshell: an MTA is not supposed to "munge" email (apart from adding Received: headers and the like); however, many local clients submit via SMTP and the mail server needs to do lots more work: rewriting email addresses, and so on. The split of sendmail's operation into MTA (Transmission) and MSA (Submission) is to support this. -- jan grant, ILRT, University of Bristol. http://www.ilrt.bris.ac.uk/ Tel +44(0)117 9287088 Fax +44 (0)117 9287112 http://ioctl.org/jan/ Whose kung-fu is the best?
