Hi Guys
 
I have noticed a dramatic increase in email delivery from my SM12 server with an error of "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond"
 
I am getting these errors from a variaty of destination servers.
 
Any ideas where i can look to try find the cause of this?

Can you provide examples?
 
Can you post the domains which are having problems and the domains they are attempting to connect to?
 
Have you sent an e-mail to mailtest@unlocktheinbox.com, from one of the problem domains, and checked the results of the message?
