Problem

For Email in IS sometimes a "non fatal Exception" occurs and it is actually handled as an unrecoverable error which results in termination of the email polling thread. Below error can be seen in the logs:

"The poll thread has terminated due to a unrecoverable error: Unable to send Event. Status: 3"

Restarting the EMAIL service or the whole IS are the recovery methods, but after a while the issue can reappear.

Resolution

For a permanent solution, the configuration should be adjusted as follows:

1. Check the value of the parameter "resultfile" from the slave.par file corresponding to the IS instance. By default, for is0, it should be resultfile=spool/runtime/is0/result

2. Check the value of the parameter "RESULT_FILENAME" from the params.Imft file corresponding to the IS instance. The value of this parameter should be the same as "resultfile" from slave.par. Change it to that if it's something different.

Starting with SP26 the correct configuration will be available also in the ./param/is/templates/email/params.Imft file
