I >realize this is likely an elementary problem, but I would appreciate >it if someone would be able to explain to me how the "Sender" and >"From" fields should be used properly so that one can post to LISTSERV >lists. sender: indicates the agent who delivered the message. from: indicates the person who composed it (not to be confused with smtp from, which is a different beast). in most cases, sender: and from: will be the same, since the person who writes a message is also, in effect, the agent who delivers it. in the case of (properly configured) mailing lists, sender: should have the listowner's administrative address, since the server (whether listserv, majordomo or whatever) is the agent delivering the message. from: will remain the address of the author. that said, your problem most likely stems from a difference between the address in the from: header and the address that the person is subscribed to the list as. for instance, [log in to unmask] and [log in to unmask] are functionally equivalent (mail to either address will reach me), but not identical in the eyes of mailing list software. this is a common problem with two solutions: 1) change the subscription from the address in the list to the address in from: header. 2) subscribe both addresses and set one of them nomail. the former is cleaner, but the latter is sometimes necessary if the from: address varies from phase of the moon to phase of the moon (an unfortunate, but common, problem). _O_ rob woiccak |< [log in to unmask]
