We have an ISA 2006 front end and SBS 2008 with Exchange 2007 for our mail server. We also have several Sharp Copiers that scan to email. None of the copiers can authenticate to our smtp mail server whether I use our internal mail server or external. Consequently, we have another server with SAP B1 that also cannot connect to the smtp mail server to enable the Outlook Integration Add on.
I've tried our internal mail server address, our external mail server address, ports 25, 587, 465, and 443.
I can open a telnet client to the mail server from the SAP server, and can authenticate a user. There is no firewall on the SAP server.
I have started the firewall query in ISA and watched it while I attempt to connect one of these devices to the mail server and no connection attempt comes across the log. Is this something that SBS2008 is causing? Like setting up a relaying connector for the copiers?
I am baffled. Any help is appreciated.
