Listener not starting up with secured IMAP on port 993
There is a mailbox upgrade happening within User whereby all mailboxes are upgraded to Outlook 2010. Changes were done to Pega email accounts/server running on Pega 7 and PRPC 6 versions.
The Pega7 listeners started up successfully. However, PRPC 6 listeners with the same values given didn't start up.
Caused by: javax.mail.MessagingException: Could not connect to SMTP host: imap-uat, port: 465;
nested exception is:
java.net.ConnectException: Connection refused
Steps to Reproduce
1. Open any Email Server in PRPC 6.2
2. Update the config to use IMAPS (i.e with Use SSL checked)
3. Update port number to 993.
The root cause of this problem is the issue with version 6.2 SP1 where PRPC EmailListener will ignore the port for outbound mail and always connect using SMTP or Secure SMTP. As the user have disabled the SMTP on their email server, listener fails to start up.
This issue is resolved by adding the below DSS setting.
Owing ruleset: "Pega-IntSvcs"
Purpose/description : email/blockResponse
Value = true
This setting will enable the EmailListener to block the test connection to the response server via SMTP.
