<sigh sigh> Nope, I'm not surprised. It's not a big issue for most folks
because my ISP services a fairly rural community and I'm probably the only
customer not using their mail server. My ISP and I did contact MAPS and
requested that they remove my static addresses from their lists, to which
MAPS replied that they would be happy to just as soon as my ISP gave them
a list of all customers and the IP addresses assigned to all customers.
Umm..... no! Enough of the drama, back the the technical stuff.

Excellent! thank you very much. This helped, and now I'm getting a
different ("better" IMO) error in maillog:
[EMAIL PROTECTED] postfix]# Sep 4 09:49:05 perrin postfix/smtp[30978]:
45886335406: to=<[EMAIL PROTECTED]>,
relay=mail.southslope.net[167.142.226.73], delay=4, status=deferred
(Authentication failed: SASL authentication failed; server
mail.my-isp.net[167.42.226.73] said: 535 (515) incorrect password or
account name)
I have confirmed several times that the password and username in the
sasl_passwords file is correct, and using Thunderbird or Evolution i can
send e-mail directly through the ISP e-mail server just fine. That is a
<TAB> between the [smtp.my-isp.net]:577 and the
MyUsernameHere:MyPasswordHere portions, perhaps is needs to be just a
space instead of <TAB>?

I'd be happy to mail it to you (or anyone else interested in taking a
look) off-list. Give me two shakes and it will be sitting in your inbox.
Thanks again for your help on this!
