Hi, In the properties of the smtp virtual server, tab delivery, advanced, you
can fill a fully qualified domain name (fqdn). That is the name that comes in
the outgoing mail headers. If you change that with a fqdn that has also a
working reverse dns entry, it should work.
Or you can use the mail server of your isp to forward your mails. Ask your
isp if they support that and what is the ip address or host name of their
mail server (or just do it and see if it works). In the properties of the
smtp virtual server, tab delivery, advanced, you can fill a smart host for
outbound connections. In this tab If you put there the ip address of your's
isp mail server it must be between square brackets, ex. [18.104.22.168].
The maximum mail size limits of your isp could be a problem when your
company sends large e-mail.
