Understanding multiple Virtual SMTP Servers
1) Other than hosting multiple domains, what other reasons are there to run more than one Virtual SMTP server?
2) This is the bigger question - A client recently acquired another *small* business with its own domain. Their solution was to add the acquired domain under Recipient Policies in the Exchange System Manager and then add those few new users in A/D - and it worked well for them. But why shouldn't they have set up a new Virtual SMTP server for the new company? I'm trying to understand the difference between running multiple SMTP servers and just plugging multiple domains into Recipient Policies.
Thanks for any help you can offer.

mass2612, the "different ports" aspect I understand, but can you give me a "real world" example of why I would need to use multiple VSMTP servers when trying to accommodate "dual homed" or "different IP address" scenarios? Thanks!

Thanks for the follow-up. I bumped the points up and will split them.
Using mulitple virtual SMTP servers is not very common. The default VSMTP server is normally sufficient for most situations. You would usually only use multiple virutal SMTP server in a dual homed situation or where you needed to have different ports/IP addresses for different SMTP domains or different policies for filtering, blocking, etc.
