Sendmail & Macro4

[d-pedley]

Hello,

I have supposedly installed Sendmail, but I am not quite sure, I am =
unsure of how to configure, the is some mention in some of the books I =
have bought about M4 which seems to stand for macro4.  There doesn't =
seem to be any help about this of maybe I cannot find it.

Can anybody help with this?  Thanks

I am running Redhat Linux 5.x and the latest version of sendmail.

Cheers.
