Hi there, just a question regarding running multiple domains in Exchange. I
am aware that this can be done and how to configure from a receiving email
standpoint - but my concerns are regarding sending email. If I register the
domain with a different ISP as the domain I am currently using, I assume
that our current outgoing SMTP server - which all our mail goes through -
will reject email originating from email addresses with the new domain which
is not registered by them? If this is the case, do I somehow have to set up
the server to route outgoing email from different originating domains
through different outgoing SMTP servers?
Hope this makes sense and someone can offer advice!
