We were able to connect to your email server on port 25. Your server either disconnected before we sent our final QUIT command or did not respond to one of our other diagnostic commands within 15 seconds.
This may be due to a network problem, or could be an anti-spam feature of your email system. On it's own this warning does not point to any specific problem, but can be helpful in diagnosis when combined with other errors.
