I am currently transitioning a small business over to a new provider.
However, the ISP is stating if I connect to their SMTP server more than 100 times a day I will get blacklisted. They stated to use DNS on the SMTP connector.
If my DNS MX record points to their SMTP server will I still be connecting to them?
I do not want to get blacklisted, they will shut the domain down for 1 hour with no work around.
