Well, I knew what the DNS servers did, but I was mainly curious as to whether
the SMTP server cached the address the first time it looked it up and used the
address when it next tried to deliver or whether the name was used the next
time.

Point taken. I didn't know that.
: The moral of the story is this isn't 100% reliable; use small TTLs for
: this to minimize lossage. If you used, for example, a 1 second TTL, you'd
: have a very small window of loss, but almost every reference to your
: machine would require a DNS lookup, with an "adverse" effect on connecting
: to you.

It was just going to be on a temporary basis, but thanks. I think that mostly
answers my questions.
