I am having trouble setting up my toaster to relay for remote clients.
I current setup is Toaster --> Firewall --> Exchange server. All
incoming email uses the Toaster as the mail gateway/filter and exchange
uses the Toaster as the smart host for all outgoing messages. I now
have a requirement for mobile devices and remote users. I do not want
to open the firewall for relaying by outside connections. I would like
to use the toaster for mobile devices and remote users (all will be DHCP
IP addresses from various providers) for their outgoing SMTP server. I
have purchased another domain and set it to be a local domain on the
toaster with a single user.
When I set the client whether it is outlook, thunderbird, or on mobile
devices it connects and authorizes the users (or looks like it does) and
then I get an error when sending saying "5.1.1 sorry, can't find valid
MX record for sender domain (#5.1.1 - chkuser). When checking DNS on
the toaster it resolves both MX records back to itself which is correct.
I don't want to change the tcp.smtp file if I don't have to.
Any ideas?
