Exchange will send external mail but not recv. it

[ryansupak]

hi, i'm trying to narrow down where the problem with my exchange 2000 is:

accounts can send external mail via SMTP connector, but they cannot receive it.
i can track messages from outside to the users (e.g., email from foo@hotmail.com), so i know mail is finding its way at least to the smtp connector.

as the last message before the NDR notice, the tracker returns: "SMTP: Advanced Queue Failed to Deliver Message"

any ideas where to start looking?

other details: Nothing really shows up in the Event Viewer for ExchangeTransport or ExchangeIS, and I have all other zones disabled.

thanks in advance,
rs

one other discovery I just made:

in the mail tracking center (in Exchange Service Manager), i was examining mails that were sent out successfully. it shows the sender as &quot;< >&quot;, which i'm assuming means that somehow Active Directory somehow can't ascertain the name of the sender.

perhaps that gives a hint to someone...
