Mail keeps changing my SMTP server settings
We've changed ISPs for other reasons, and the problem has persisted. We've worked with our mail provider and pretty much eliminated them. So now we're left with a freakish Mail hiccup that we can't solve (and is a potentially big problem because we're a small business, but not everyone who uses the computer has any clue how to change smtp settings).
We'd like to stay with Mac mail because everyone knows how to use it, so we're hoping to get some help from the forums before we give up and move over to Thunderbird.
