Hello,
This week suddenly a lot of people are having trouble sending email. They get this message while before everything was working fine. Sending using SSL is working fine but when they use no ssl with mail.domainname.nl it returns this error. So nothing changed on their computer.
"None of the authentication methods supported by this client are supported by your server."
Did something change or do i need to make a configuration change somewhere since the clients seem to be configured just fine.
I am confused
Thanks
