This is a follow on to an earlier question I posed. The situation is that we have a company where one part is in Asia and other other in the US. They are not connected in any way, network, vpn, nothing. But they want to share an email name space. Our side (US) uses Exchange 2003 in a front-end, back-end, DMZ setup. The have a web based email. Everything works fine except that since they do not use a network with files servers, they share files via email! ARRGGHHH. And they expect to continue to accept 50MB files inbound. I thought (a kind hall of famer here agreed) that since we are only routing their mail, the size limit wouldn't be a problem. But it is. Our 10MB limit stops anything larger even when when it's being routed to Asia and doesn't go to our mailboxes here. They want to go live on Monday so this is really urgent. (Isn't everything??) :-) I'm thinking of trying this: Up the limit on the front-end server to accompdate them -- there are no mailboxes on that server -- and see if that fixes it. Anyone had any experience with this?
