I am having trouble with connecting my smtp server.
Ports 465 and 587 are open.
I am using a wp plugin wpresponse pro as a small auto responder, when I use my hosts smtp then everything is fine, but when using MXRoute it fails to connect.
I’ve reset the email password and now am getting error “550 authentication required” when I try to send emails into the account.
Any advice will be very appreciated.
