mail command and "from" header

Using mutt, I can put a line in .muttrc to change the "from" header: my_hdr From: paulsen@texas.net Is there an equivalent configuration option for the mail command? (I looked at "man mail" and /usr/share/doc/packages/mail>manual.ps.gz and found lots of options, but none for this.) I am able to configure sendmail to change the host name, but haven't found a way to change user ids. (Alias seems to only affect the "to" header.) -- ____________________________________________________________________ Robert Paulsen paulsen@texas.net
