I found this out the hard way - MH on Unix kept putting in a Sender: because I had provided a From: field different from my Unix login. As a result, I had to put both my user-friendly and actual user@node addresses in the POSTMASTER variable. (For the curious, nmh 1.0.4 provides a 'masquerade' option to disable the addition of Sender:) -- Valdis Kletnieks Operating Systems Analyst Virginia Tech
