Hello Brian !

I will do, but I see here, on forum a lot of cases that are reolved directly here.

https://www.symantec.com/connect/forums/messagelabscom-connection-timed-out

https://www.symantec.com/connect/forums/receiving-connection-timeout-messagelabscom

https://www.symantec.com/connect/forums/cluster6usmessagelabscom-connection-timeout

etc...

It is possible to solve my case here?

Thank you!

Resgards,

Xavi.

Symantec employees who work with the email security product frequent this forum so hopefully one of them will see this and assist.

I hope it.

I sent the message where you indicated but I read that they can last 1 week.....

I need to solve it quickly because my customers need to send eveyday emails to a domain protected by messalabs.com

Thank you vey much, Brian !

Xavi.
