Recently we have setup our NAMESRV machine to send queries to a remote server for resolution. We modified our Mailer tables so mail with internet addresses would be sent to our SMTP rather than INTERBIT. This works fine until the remote server goes down, or something in between (DACU, Ethernet, etc.), in which case the mail gets returned by SMTP. When using a remote server with NAMESRV, can you configure SMTP to know the difference between (Unknown Address) and (Any Other Failure) ? Currently SMTP returns the mail when there is any failure. We would like SMTP to keep the Mail until the Server comes active, then try to resolve the address.

Could this be a consequence of a NAMESRV bug that make it return 'Name error' (rc=3) in some cases when it should only be allowed to return a null answer ??? /AF

This problem is fixed in the SMTP/MX code, which will be on the 1.2.2 PTF tape. SMTP will now requeue mail for resolution if the remote name server is not available. The old version had no wait of holding mail for later name resolution. Bill Rubin IBM TJ Watson Research
