Dear Mark and all others,
many thanks for your help so far.
I am just starting to setup this subdomain, Mark advised me to.
One thing regarding the Reverse DNS entry:
How can it be necessary, to set up this record? Just imagine a server,
where multiple domains are hosted, but the server only has one IP.
If the ISPs really require rDNS entries, which suit to the mail originating
domain, one would always need a 1:1 mapping of IP and domain, preventing
multiple domains on a one-IP server, isn't it?
Kind regards,
Sascha.
The server name does not need to be connected to the domain the mail is
'from'. My outgoing mail uses an outgoing SMTP server not in anyway
connected to my domain. If someone REALLY wants their mail to fully
appear (even to people digging into headers and server logs) as if it is
coming through a dedicated mail path, then they are going to need to pay
their MSP for the additional IP addresses to make that happen.
