Now, I can't help you, Rigo. I'm no SendMail or SquirrelMail expert. However, I do note that you didn't provide enough information anyway.

Do you need to do anything more than simply get SendMail to place files where SquirrelMail can find them in a format it understands? {^_^} ----- Original Message ----- From: "Rigoberto de la Cruz" <rigodcx@xxxxxxxxx> > > I'm trying to configure sendmail and squirrelmail. > Sendmail's official website does not have a good > example on how to customize sendmail.mc Does anyone > know a good website where I can learn more about > sendmail? can someone send me their sendmail.mc as an > example?
