I have a Plesk panel and recently migrated to a new data center (DC) from Contabo. I imported the websites using the import tool, but there are some issues, such as not being able to send or receive emails.
I contacted the DC, and they enabled all ports as “any.” Within Plesk Firewall, I enabled ports 25, 587, 465, 993, and 995 for both TCP and UDP.
Still, when I go to the email settings, I get the following error message, and I am unable to send or receive emails:
“You cannot send emails from Plesk because outbound connections on TCP ports 25 and 587 are blocked. Check the firewall settings or contact your hosting provider. If you are sure that the ports are already open, Plesk can recheck them.”
Has anyone experienced a similar issue before?
