[Q]Squid and internal mail/web?

I read through the faq quickly and didn't see the answer to this
anywhere. I am considering quoting linux to a customer to solve their
internet connectivity needs but I have a quick question about squid's
abilities.

Is it possible to allow incoming requests for mail/web through squid?
i.e., can I set it up so that a user on the internet can try to connect
to www.proxyclient.com, where the name resolves to the proxy server, but
then, when the request hit's port 80 it translates the number to an
internal ip address?

Does squid work as such:

router to internet
    |
    |
    |
linux Eth0
    |
  squid
    |
linux Eth1
    |
    |
    |
internal network (private ip's)
    |
 int mail server

Can a connection to Eth0 port 25 be translated/forwarded to a connection
to the int mail server's int mail server port 25?
