We are currently running
a root server with Debian 6 and Plesk 10.4.4. We have some virtual hosts using one
IP adress (shared) - e.g. example1.com - and another virtual host using
a dedicated
IP address (example2.com).
Is there
a way
to configure postfix
to do the following
Always use the
IP address of the virtual host
to which the e-mail account belongs (so that an e-mail
from [email protected] will originate
from the shared IP-Address and an e-mail
from [email protected] will originate
from the dedicated IP?
Use different certificates for TLS for example1.com and example2.com?
If the latter is not possible: Could any problems arrive when using example1.com as certificate for example2.com users? Of course, example2.com users would have
to configure their clients
to use example1.com as the SMTP server name
to avoid annoying security warnings. But if we still would be able
to get the effect of the first point that would still be acceptable.
