Email Listener fails to start and does not consider useSSL flag



Email Listener fails to start due to lack of SMTP port for SSL on Email Server/Account Rule form. By default, enabling 'Use SSL' uses port 465 and you want to specify a custom port viz 780
There is no option to specify this custom port for SSL connection when using SMTP. This causes email listener to fail.

Error Messages

javax.mail.MessagingException: Could not connect to SMTP host:, port: 465; 
nested exception is: Connection refused 
at com.sun.mail.smtp.SMTPTransport.openServer( 
at com.sun.mail.smtp.SMTPTransport.protocolConnect( 
at javax.mail.Service.connect( 
at javax.mail.Service.connect( 

Steps to Reproduce

Modify Default Email Account form and select use ssl checkbox and do test connectivity. It should fail with the same error: 
Data-EmailAccount.Default: MessagingException caught connecting to email server; javax.mail.MessagingException: Could not connect to SMTP host: <IP Address>, port: 465;

Root Cause

The root cause of this problem is a defect in Pegasystems’ code/rules.


This issue is resolved by hotfix item Hfix-10427. Email Server now has Advanced tab under where java mail properties can be added for Email Listener to use such as mail.imaps.port or mail.smtps.port
