Hi,
I have a weird question. Suppose that you have something like this: Client C, using Email Client E, sending email message M, via his ISP SMTP relay S, to user at host T. That's all normal. But here is where things get interesting.
Suppose that T does not have an MX record, but *does* have a CNAME alias to a host R. Thus, when S looks up the MX for T, nothing comes back. My questions:
1) does a standard govern what happens?
2) will *all* SMTP relays, including S, look up the MX record for R, *NOT* the A record?
3) will *all* SMTP relays, including S, look up the A record for R, *NOT* the MX record?
4) if neither 2 nor 3, is it that neither *ever* happens, or rather, that sometimes it's done like 3 and sometimes like 2?
This question strikes me as independent of other questions for which the appropriate response is 'RTFM.' Thanks for your help,
-Eddie
