I have to Block port 25 i,e SMTP TCP port..To block outlook express..

[Stefano]

so, as far as I understand, you wish no client can send mail but SME?

if so (and your SME is in server & gateway mode), enable smtp proxy and you're done..

If it is port 25,then ok..If I have to block all ports except browsing...Then what I have to do...What code I have to use...Is there any specific code for that???

[Tejaswini]

I checked this by using code,whatever mentioned in http://wiki.contribs.org/Firewall    but this is not working...

[Stefano]

ok..

first of all I ask you to read the documentation and to search the forums and the wiki.

then.. SME is not designed to filter outgoing traffic.. you could try Dansguardian, but if you want to block p2p and so on, the only thing you can do IMVHO is to use a firewall like pfsense, m0n0wall, IpCop ect in front of your lan.
