I use Plesk in a vps environment (Lightsail) and since signing up with mxroute, I have uninstalled my mail server that comes along with Plesk for managing emails. Doing this stopped my WordPress sites from sending contact form messages. I’d also assume this disables the forget password functionality from working.
So I was looking around for help to get this working again and chanced upon this plesk help doc which says:
when the mail server is not installed or prohibited from sending outgoing mail, you face the problem: Plesk still needs to send notifications, and customers’ scripts may need to send emails. To solve this problem, Plesk can send outgoing mail through an arbitrary external SMTP server.
And recommends the following to be enabled, which I’ve already done.
My questions is, would enabling this option in Plesk, and
setting up mxroute details for external SMTP server help the websites to start sending contact forms messages again?
