if you have a firewall that is publishing your exchange, please make sure that you have a dns rule that allow dns from internal to external.

Check your mail server public IP if its black listed :

Also check if there is a PTR record for mail IP on the ISP dns. (for example 1.1.1.1 points to mail.domain.com)

i forgot to mention to verify if you have created a send connector to internet? be aware that send connectors are not created by default.

If you are using a smart host and the queues are empty, then the problem is with the smart host. You need to speak to them to find out where the messages have gone.

While a PTR on your IP address is good to have, with a smart host it isn't necessary.
