I am having problem with some gmail users. Getting these errors:
Technical details of permanent failure:
The recipient server did not accept our requests to connect. Learn more at https://support.google.com/mail/answer/7720
[xxx.xxx.com. xxx.xx.xx.x: socket error]
Any mail that comes in, arrive on the symantec messaging gateway. I would like to know whether there is a way to troubleshoot the problem. For example log files having the details.
Strange thing though is that I just tested with my gmail account and mail delivered immediately. We are having problem only with a few users.
Thanks to help.
