[clug] Sendmail Config

[Dr Mikel]

Hello all,

Im trying to send emails to people as if it were from someone else. e.g.

no-reply at mydomain.com

But for some reason it stills reads as root at hostname.domname, when I set it 
to go out our SMTP server our filter blocks the message because it can't 
resolve root at hostname.domname.
Most filters these days do the reseverse DNS lookup, and there is no way 
root at hostname.domname is ever going to resolved.

Is there away around this?

Cheers.

Michael.
