Hi everyone, hope you can help with an e-mail problem that may be security related.
We have a client that want's us to handle information enquiries on their behalf. The idea is that any mails sent to info@theirdomain are picked up and handled by us. Our client also wants any responses we send to appear to have come from them, not from us.
We should mention at this stage that both we and our client use SBS-2003 domains and we both have our own Internet domain name names with SMTP mail coming directly into our respective SBS Exchange servers. Both businesses are connected to the Internet via ADSL broadband lines. both SBS servers use a dedicated external network adapter and both have a public IP address on their external interfaces.
We see two options to make this arrangement work. 1) Our client forwards all mails to info@theirdomain to a mailbox on our server. We deal with them and respond. The problem is that the responses will appear to come from us unless the source address is 'spoofed' (obviously causing untold difficulities that the Intenet and nobody else wants). Option 2 is that our client creates a mailbox on their Exchange server that we can log onto, deal with the mails and respond accordingly. This is elegant, makes sure the responses appear to have come from our client and prevents duplication of mails and uncertainty.
The ideal option is #2 but we simply cannot log onto our client's mail server. They have enabled 'Outlook via the Internet' when running their Internet Connection Wizard but if we try to set up an Outlook profile on one of our desktops (Outlook 2003) to connect to their server (using either its IP address or FQDN) we are getting a 'cannot connect' error. We can ping their server and connect to it as an SMTP server from the same desktop so the network connectivity is fine.
Any ideas as to why we cannot connect would be very welcome.

PS. We cannot use Outlook Web Access for reasons I won't bore you with. It works fine (we tested it) but it simply doesn't do what we need.
