3196924 - Certain E-Mails are not polled by the Mail Sender Adapter

Certain e-mails remain in the mailbox and are not processed by Cloud Integration:

1. The Message Processing might not start at all.
2. The Message Processing starts, but new Message Processing Logs appear in the Message Monitor with each poll, remaining in the status "PROCESSING" and eventually changing to "ABANDONDED". The logs indicate the message could not be polled.

The following error might be seen in the Cloud Integration traces:
