(PM) Email Only Filter?

Can anyone help me setup an e-mail only filter? I currently
have:

permit udp dst eq 53
permit udp src eq 53
permit 0.0.0.0/0 xxx.xxx.xxx.0/24 tcp dst eq 110
permit 0.0.0.0/0 xxx.xxx.xxx.0/24 tcp src eq 110 estab
permit 0.0.0.0/0 xxx.xxx.xxx.0/24 udp dst eq 110
permit 0.0.0.0/0 xxx.xxx.xxx.0/24 udp src eq 110 estab
permit 0.0.0.0/0 xxx.xxx.xxx.0/24 tcp dst eq 25
permit 0.0.0.0/0 xxx.xxx.xxx.0/24 tcp src eq 25 estab
permit 0.0.0.0/0 xxx.xxx.xxx.0/24 udp dst eq 25
permit 0.0.0.0/0 xxx.xxx.xxx.0/24 udp src eq 25 estab
deny tcp dst eq 80
deny tcp src eq 80
deny tcp dst eq 21
deny tcp src eq 21
deny tcp dst eq 23
deny tcp src eq 23

(where xxx.xxx.xxx.0/24 is my class C that has the e-mail
server on it)

in the filter table as "email". In my Radius entry I have

myname Password = "mypass"
Service-Type = Framed-User,
Framed-Protocol = PPP,
Filter-ID = "email"

The blocking of the ports 80,21, and 23 seems to work, and
the permit on the DNS port (53) works, but for some reason
I'm still not getting e-mail to go through - it hangs up
trying to reach the server.
