Solved WebMail not being delivered

[troypulk]

Hello,
I have been trying for a long time to see if my mail would be delivered from my Thunderbird @wavecable.com account to my webmail @vivaldi.net account, but it was not important but I'm tired of getting the following error message so I'm asking now.

Does anyone know what the problem would be? I have never been able to send mail from @wavecable.com to @vivaldi.net.

Thank you

Hey @troypulk!

@wavecable.com doesn't have their mail servers configured according to common standards that we adhere to.

The local email server name for the email server must be reflected in the DNS. Whether the email service provider (ESP) accepts or rejects incoming emails in case this requirement hasn't been fulfilled is for each ESP to decide.
I've sent you some more details specific to your mail server in a private chat message.
