'From' is actually generated by the delivery agent on "your" (the recipient's) mail server when the mail is delivered into the system mailbox. Not all mail systems use the Unix mail delimiters; PMDF uses a string of four ^A characters to begin and end every message, thus no 'From' is necessary (and is often not generated). PP> 2) your MUA or your MTA adds a "Sender: " header, in perfect PP> conditions this should be done by the MTA. MTAs are technically the only entities that are supposed to add 'Sender:'; this is what the -s switch to sendmail is for, for instance. MUAs should not generate 'Sender:' fields, and they should ignore this header in messages received. PP> 3) your MUA adds a "From: " header--if missing, the MTA might do it. The MTA *must* do it if the MUA does not. It is required that the MTA do it if the MUA has not provided a 'From:' header. -----BEGIN PGP SIGNATURE----- Version: 2.6.3 Charset: noconv iQCVAwUBMY465p6VRH7BJMxHAQHkMAP/XmuThI1d0x6qkbkQ8DVSEsdEidNic6hy ecOUgoO+dIp890pb0jUN94jpwXuDWBFW0l7ABFKz1Ca9aWIT45VS/anG0bwPXkeE 7T2shy18s4ct13hS8m43p0oIagxnlw5GcSThJlFeGNtvtVIOllm0JWiiF4UyAhVT dJJeYq2kvAo= =pv1s -----END PGP SIGNATURE----- -- Rat \ Happy Fun Ball may stick to certain types PGP Public Key: Ask for one today! \ of skin. http://www.ccs.neu.edu/home/ratinox/ \
