set up an SMTP relay on the local network which sends to the Office 365 SMTP server
We are migrating from in house Exchange 2007 to Office 365. Our VB based order management app uses SMTP to send emails to customers. Instead of doing a ton of recoding to use a new SSL local component, are there any issues with just setting up a local SMTP relay to Office 365? If we have the local SMTP relay server, than we can stick with port 25 and non-ssl. The relay would send SSL however to the Office365 SMTP server.
Environment is Windows Server 2008 R2, which the VB based app runs on.

Can the receive connector be setup to use a IP Subnet without listing all of the IPs? I have a Class C Address Space and the servers/devices sending mail use Dynamic NAT and could be one of about 150 possible addresses.
Yes. The connection filter and receive connector can use a Class C range by CIDR notation or as a range of IPs.
