Sorry for the delay, my replys on gmane.mail.postfix.user are
not seeming to get thru so trying the mail list.

Thanks for info on comcast.
That mail account is not the one I use... IPs change overtime but my email has
remained the same since 1996-7 or so. I want my email address's smtp server
newsguy.com to do the relaying. and have done so for quite a goodly while.
I'd like to get postfix to let me do that.
