We have a problem with a mailserver.
The hoster is to stupid to fix it as it looks like.
Debian Server with Exim as MTA and ISPManager as Servermanagement-Software (like Confixx or cPanel).
The server has multiple IP`s. We got it installed with one IP and added the additionales ones after.
Domains on the additional IP`s can`t receive emails. Emails cant be sent(via webmail) - but not received. We always recieve a bounce-message like "550 relay not permitted".
As it looks like the AUTH aint working also...
access to pop-boxes work via outlook.
You task is to modify the server-/exim-config that way that all domains on all ip`s can receive emails.
