When inbox is set up for Auto Reply, it goes into infinite loop



When inbox is set up for Auto Reply, it goes into infinite loop

email listener listens to emails and replies for those emails. If the User's inbox is set up for Auto Reply, it goes into infinite loop. DSN don't work.

Error Messages

Not Applicable; no error message 

Steps to Reproduce

  1. Configure Email Listener that will respond back on receiving an email.
  2. Configure Out of the Office/Auto reply for a email account; Email from this account to Email listener inbox.
  3. Email listener responds back which inturn triggers another email to email listener; hence infinite loop.

Root Cause

The root cause of this problem is a defect in Pegasystems’ code/rules. Expected behavior is that Email Listener would not respond to the auto reply/thank you emails.


This issue is resolved by hotfix item HFIX-22658

New Dynamic System Setting "Email/AutoReplySubject" is introduced in Pega-IntegrationEngine ruleset which should contain comma separated auto reply subject string that it should avoid responding back to.
