I don't know the connection limit for Windows 7 but even if it's 20, that's not enough by the sounds of it. Even installing Mercury on Windows 7 won't help - you still have over 20 PCs needing (possibly) to talk at once. The limit applies to the shared folder, no matter whether Pegasus or Mercury is using it.
Don't fall into the trap of "most of the time it'll be no more than 8 people at once, so 20 should easily cover it". The boss will quite rightly tan your hide if you give him a system which, one day, when the office is busy, starts falling over simply because you thought you'd never see so much traffic. Work out the max and ensure you can deal with it.
Here are a few options for how you might move forward:
A) Invest in a new server with a server OS, such as Windows Server 2008. Even an old copy of Windows 2000 Server on an old PC will do you fine and might be cheaper.
B) Use the server of the person you mentioned. Such a decision (using non-company resources) would clearly need to be OKd by your boss.
C) Install an appropriate, free, non-Windows OS on your server that provides a mail server program. You'd not need Mercury but I imagine that set-up and security would be more complex.
D) Find two or three desktop PCs in the company that could reliably be used as "mini-servers" and then install Pegasus onto these. Each of these would service no more than ten specific employees, and so everyone could use the mail system at once if necessary. However, these separate installs of Pegasus will not be able to "talk" to each other, so you'll then need Mercury to be installed on one, central server and set the Pegasus installs to route all mail through Mercury.
Of course, after I've typed all that, Thomas or 'Dilbert' will pipe up with "actually, forget all that - if he does X, Y and Z, he'll be fine". It's been a while since I actually played with a live network, so I definitely yield to any advice from those sages...
