Corrective Action:
The solutions is to adjust the GWIA SMTP/MIME settings for the "Intervals to retry a deferred message".
The default GWIA settings are 20,20,20,240. Hence need to change the setting in GWIA to resolve the issue.
  1. Open the properties of GWIA object .
  2. In SMTP/MIME tab  change the option settings for "Intervals to retry a deferred message " to 3,10,20,20,20,240 .
  3. Click Apply > Ok . This will restart GWIA and resolve the issue for send failure.
