There are not much traces on the logs that you have sent. I could see
only few traces on Mail Sending. Please send these details when the
issue occurs.

Take a Thread dump when you see mail fetching is not happening
when there are more emails in the inbox but not getting fetched in
the application. Also Zip the Serverout files from
SDP-home/server/default/log folder and send us.
