pine and sendmail

[rturner2 at texasisp.com]

hi all,
does any one have a sendmail.mc file 
that they can send me?
i am working on setting up sendmail and pine,
but i am not sure what to do first.
i have fetch mail and pine recieving messages ok,
but when i send a message out it puts the wrong reply address on the message.
i need some config files that i can look at to help me figure this out.
thanks in advance
randy
