Switched this domain to Cloudflare 2 years ago and it was working fine until recently. Hosted on Hostgator; their support insists it is DNS related. Mail server is NOT at Hostgator, it is offsite, and it is not proxied (it is gray cloud).
Attempted to use PEAR::Mail and another SMTP mail option, and when attempting to reach mail.THISDOMAIN on any port, the response times out.
Attempted telnet and ssl to mail server and similarly timed out.
Has anyone had this issue? Have a solution or suggestion?
Thank you for reading.
