I want to use thunderbird as an internal (intranet) email client. I'm using Postfix as the server. I've defined an smtpout.mydomain.net server to thunderbird

However I cant send an email. When I try I get the following:

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) smtpout.ids4zos.net is unknown. The server may be incorrectly configured. Please verify that your Outgoing server (SMTP) settings are correct and try again.

I've defined smtpout.ids4zos.net to my DNS I'm using port 25 I've defined my domain (ids4zos.net) to Postfix. What am I doing wrong ??

Probably name resolution isn't working. Check your DNS config and make sure you set up the correct DNS server on your computer. This isn't a Thunderbird problem.

Hello Christ1.. The problem is actually with my Postfix configuration.

Thanks for your reply.
