Damn, got caught with this bug this morning. Opened my email to see Outlook downloading 800 odd emails. WTF!
Checked here and saw this, did a quick regress to see if that would work till I could sit down and sort it later.
Still more emails, oh well downloaded the latest and it finally seems to have stopped.
I am now running 2.4.1-7, the previous was 2.4.1-4 I got it on the 1st of Feb and the error didn't start till last night.
Doesn't really matter now as it all appears fixed..
Cheers
Mark
