Show reason for 'Rejected message by MTA'
Created: 30 Apr 2014 | 2 comments
We do not receive mails from a few mail gateways.
In the 'Message Audit Logs' you can find mails with action 'Rejected message by MTA',
but there is no clue why this message was rejected.
It could be because of:
- Connection Classification
- Directory Harvest Attack
- Email Virus Attack
- Local Bad Sender IP
- Symantec Global Bad Senders
