Hi

after an upgrade to dnn 6.2.5 we stopped recieving emails from our ticketing system and i've upgraded the ticketing system to and installed oldtutle ticketing system version: 2.0.6 and i've checked under host settings my smtp is working fine. 

Under the scheduler i'm recieving the following error below, please help.
