We are repeatedly getting these below warnings for some of our users, al though we have no complaints from them yet, we need to know why these warning occurs.
So it would be help full if some one explain these warning msg in detail.

Please don't spam the list with multiple postings of the same question.
Most people do not have crystal balls, and those that do often find them
broken, so it would be helpful if you could provide at least a bare
minimum of details about your setup...
What version of dovecot is this? doveconf -n output? Singe server or
cluster?
