MAPI Connector on outlook, failed to send message smtp server reponded with -.

Post by kiamori » Fri Apr 30, 2021 9:34 pm

Ran into this error today with a client, very odd because it was showing in the ME logs but the email never actually sent out.

It seems the email was being corrupted by AVG antivirus, so if anyone else is having this error try disabling the 3rd party AV solution on the client machine. Disabling/uninstalling AVG did solve the problem.

Here is the log for reference:
Trace: Tracing message with Message ID [795D639E0F4143C99808D95D2590A96E.MAI] from the SMTP Inbound Queue

Result: [795D639E0F4143C99808D95D2590A96E.MAI] was not routed from the SMTP inbound message queue by the local MTA Service.
This may indicate the message was never fully received, or rerouted/deleted by a third party application or filter.
If the server is in a mail cluster, check logs on other servers.

SMTP Debug log matches:
04/30/21 13:37:04 ME-I0070: [795D639E0F4143C99808D95D2590A96E.MAI] (recv) socket [1828] was gracefully closed during [DATA] command by the remote client {HIDDEN}.
Important: Message ID [795D639E0F4143C99808D95D2590A96E.MAI] has not been routed through MailEnable queues. Check the log details for the reason. If in a cluster you will need to check each cluster server log files.
