On a more general note, if I'm trying to relay messages out
through my ISP's SMTP server & my account there, why is my
postfix even doing DNS lookups? I thought I could set this
up as though it were, say, a Thunderbird client, send up
messages to the ISP's SMTP, in effect saying, "Here, send this
for me. You handle it." In all the reading I've found in web
pages, I guess I'm still confused about the "division of labor".
I can send mail with Thunderbird through my ISP on a different,
more modern system.
