I really like Un*x "mail," but one thing I can't seem to get to work on
NetBSD 1.4.1's mail is editing of the To: and Subject: headers while the
message is loaded into vi. I also have some macros I use in vi to do
some charset conversions that need to add mime headers. I've been able
to do this since SunOS4.1, and still do it on Solaris2.6. Looked through
the man page for mail, and revamped my .mailrc file, but to no avail.
Any tips, pointers much appreciated. TIA.
