Hi,
Can you help to issue below?

"TCPIP" 3668 "2020-04-10 14:59:39.941" "DNS - Query failure. Treating as temporary failure. Query: gmail.com, Type: 15, DnsQuery return value: 1460."
"DEBUG" 3668 "2020-04-10 14:59:39.941" "Failed to resolve email servers (MX lookup). Domain name: gmail.com."
"APPLICATION" 3668 "2020-04-10 14:59:39.941" "SMTPDeliverer - Message 33237: No mail servers could be found for the address ???@gmail.com."

Please note that currently the relevant Email box is fine to receive message.

Failed to resolve email servers (MX lookup). Domain name: gmail.com."

Quite self explanatory. Your server can't resolve gmail.com so you have a windows dns problem. Review your server's dns configuration.

Soft that and hmailserver will take care of the rest.

Hi,
It was everything fine few days ago. Due to the newly created Firewall rules, issue happened. Which Firewall rule could be the reason of error?

I don't know. I weren't there.

Reverse whatever you did.
