2 Mailservers behind Watchguard ...

Hello @all,

I configured two mail servers according to this example:


I can send/receive E-Mails from both servers e.g. to Outlook365 ...

But if I try to send a mail from Mail Server A to B - the mail server B cannot connect to the mail server A because it's connecting with the internal IP of the Watchgard - in this case ... I thought it would connect with the external IP ?

So what do I have to do that this works ? I tried to set the trusted flag to the SMTP connection of server A - I can connect - but the spam filter does not accent connections from ... allowing this would create security problems -

so what can I do ?

Thank you for help.
