It's not a firewall issue. I see the same thing from our server with:
telnet 127.0.0.1 110
with different values being returned before the @ on each session.
IPSwitch probably changed the banner recently, I'm also at 8.01 hf1.
Per http://www.faqs.org/rfcs/rfc1939.html
"4. The AUTHORIZATION State
Once the TCP connection has been opened by a POP3 client, the POP3
server issues a one line greeting. This can be any positive
response."
So, after the +OK it looks like anything can be returned.
