Resolve 'Something went wrong :: javax.mail.MessagingException: Exception reading response' in EngageOne Digital Delivery (formerly E-Messaging)

Issue

E-messaging unable to send emails due to SMTP connection error, with following entries in the EngageOne Digital Delivery application logs:

<Datetime> [EM] ERROR [pool-<n>-thread-<m>] AbstractMessageSender.doSend(X) | Exception reading response
<Datetime> [EM] ERROR [pool-<n>-thread-<m>] AbstractMessageSender.doSend(Y) | Something went wrong :: javax.mail.MessagingException: Exception reading response

Cause

This could be caused if SMTP server was running over SSL (Secure Sockets Layer), and SSL was not opted in the Gateway settings under EngageOne Digital Delivery user interface.

Resolution

UPDATED: July 19, 2017
Enabled 'SSL' checkbox in the Gateway (using which email are being sent) settings under EngageOne Digital Delivery user interface.
