> are you sure about that? He's right. Check the RFCs. Also, your code will block mail if there's a temporary DNS error. You should distinguish between SERVFAIL and NXDOMAIN status codes from the DNS lookup. Also, some domains can publish bogus MX and/or A records, meaning mail will still sit in the queue until it times out. If you search the mailing list archives for "Bad MX", you should find some more complete solutions.
