Thanks anyway... It works fine for me: As I said, it works fine for [almost] everybody _except_ AOL.. I would expect it to work for you with that statement, wouldn't you? Amusingly, the two lines in the middle are a message from you coming in. Yes, that *is* amusing... > (we already filed GNATS on it). What's the PR number? 1714? I don't remember actually, but if you search on "named-xfer" you only see 2 pr's show up: one for a missing binary, and one for this. > Does anybody know what to do about this? And, are we > the only ones who have this problem? I don't know of anybody else. Nevertheless, we received several replies along similar lines, all of which had the same resolution. > Attached is a perfectly typical header from tonights batch of notices... > > ----- Transcript of session follows ----- > 550 sysadmin@mfn.org...

This could be a problem with them, or a problem they have with your stated DNS servers: Actually, if you look at the message generated by their hub, it's not that they can't find the domain or the name servers, it's that they can't find a *host* named "mfn.org". > *** Request to ns2.mfn.org timed-out Came in at approximately 0215, so NS2 was probably in the middle of backing itself up (it is scheduled to begin it's dumps at 0210), but this _is_ disturbing, I'll have to keep an eye on this... They *should* try both name servers, but there's a good chance that they just time out. I'd recommend getting your name server fixed, and that will probably solve the mail problem. No, the problem was that AOL couldn't deduce that our MX record was for the entire domain, and not just for greeves. Fixed with a bogus A record, rather than the CNAME approach I took.
