"my_hdr From:" vs. "set reverse_name"

[DuCharme, Robert]

In my .muttrc, "my_hdr From:" seems to override my set reverse_name heading,
but I want it to be the other way around. I only want the "my_hdr From:"
return address used for new mail and the reverse_name one used for replies.
Any suggestions? (Warning: I haven't used Mutt macros yet--is there a little
tutorial on them anywhere?)

thanks,

Bob DuCharme
