HT3228 100s of "Delivery Subsystem Failures"

Question

Dear All,
After setting up my POP accounts to sync with my iPAD and iCloud I receive 100s and 100s of Delivery Subsystem and [email protected] in my mail box.
I disabled the sync function on both iPAD and PC and still receive this rubbish all the time.
Please help me get rid of these blabla messages and properly setup the POP mail account as it is my official mail that I use for work.
Below is an example of this rubbish messages:
Thank you.

Answer 1

OK, I've discovered the 10.6 issue is a bug in Kerio Mail Server 6.7.2 and is scheduled to be fixed with the release of 6.7.3.
The 10.5 issue remains open.
