How to set the "From:" field value on demand in Sendmail?

[micotao]

Hi, All:
When we use mailx command to send email to some specific email address, can we configure the "From:" field value? I mean, by default, the recipients will see the From: as root@<host>.<domain>, but can this be configured on our demand? Say, we don't want it to be displayed as "root@<host>.<domain>" at the recipients side, we want it to be displayed as "ROOT,<Host>" or whatever we need.
Can the "From:" field be configured on demand for sendmail in Linux/Unix? How can we do it??
Thanks!!

I believe there are two ways, somewhat dependent upon versions...

You should be able to set the "-F" flag on the command line.
You can also embed the "From: user@example.com" as part of the message body itself (at the top of the file of course). Don't forget to set "Reply-to: user@example.com" also!
