    Tech.support kerio-connect:

    Please contact messagelabs.com and ask if they can whitelist your server or increase the timeout for smtp.

    Thanks

    Hi Aleksandr,

    Check Brian's response below:

    https://www.symantec.com/connect/forums/connect-cluster6usmessagelabscom672192475225-connection-timed-out#comment-12108101

    This normally works when you submit your query to the email listed. Symantec employees don't always trawl the forums as it is community-based, so this should be your first place to start on the email above.

    Thanks!
