1/2 of the notifications Quarantined

I have searched everywhere I can think of and found nothing. I have my Dude server set up to send emails on status “up>down” & “Down>UP” I have Exchange 2010 and the account I am sending to (mine) is a mailbox on the same exchange server.

The issue is that test messages go through, as do messages telling me that the probe went from down>up but when it goes up>down the message gets Quarantined.

is there any difference in the emails between the 2 other than the text body?

what do you mean by quarantined? Do you mean placed in “junk mail” folder?
