I am running exchange 5.5, SP4 on NT4, 6a server. Lately, I have had a few emails get kicked back to senders with the following MTA looping error message:
The following recipient(s) could not be reached: Joe smith on 3/13/2002 12:05 PM The recipient was detected looping within the message transfer service The MTS-ID of the original message is: c=US;a= ;p=ORGANIZATION;l=VASRV2-020313170505Z-27464 MSEXCH:MSExchangeMTA:HQDA:DADC012 My event log also has a lot of the following warnings: Event Type: Warning Event Source: MSExchangeMTA Event Category: Interface Event ID: 4283 Date: 3/14/2002 Time: 8:09:04 AM User: N/A Computer: VASRV2 Description: Unable to recognize an internal message identifier. Internal connection handle (LPI) 1-15-2 Error code: 8464 [POP4 POP4 UP 7 228] (14) I am not sure if the looping is related to the event ID 4283 MTA warning. I'd like to resolve both issues but the mail looping seems to be the bigger issue right now. Would appreciate any guidance. Thanks in advance.
