Summary

A change in max number of pyEmailMaxResends (from 3 to 5) and restarting the web server does not change the value. 
 

Error Messages

Not Applicable

Steps to Reproduce

1. Open Pega-ProcessEngine • pyEmailMaxResends and change all values to 5 (from 3)
2. Stop and Start web server
3. Stop connection to SMTP server (unplug network cable)
4. Check log for retry (search for ERROR - Data-Corr-Email that failed to send)

Root Cause

A defect or configuration issue in the operating environment. 

pyEmailMaxResends works only for recoverable error. The use case here is of a non-recoverable error and hence, pyEmailMaxResends is not considered.

Resolution

Perform the following local-change:

There are the two errors which are considered as recoverable errors.
 
if(cause.getMessage().toLowerCase().indexOf("connection reset") >= 0) 
{ 
recover = 1; 
} 
} if(e.getMessage() != null) 
{ 
msg = msg + ": " + e.getMessage(); 
if(msg.toLowerCase().indexOf("could not connect to smtp host") >= 0) 
{ 
recover = 1; 
} 

This is in function, pega_integrationengine_default.SendEmailMessage.

As the use case is of non-recoverable error, add the error in function, pega_integrationengine_default.SendEmailMessage.
