Squid: reverse proxy security advantages

["Alejandro Facultad" <alejandro_facultad@xxxxxxxxxxxx>]

Dear all, I have a webmail which must be accesed by users from another 
network.


The content of the webmail is not static obviously, so the content caching 
is not an advantage here. Also the webmail is just one server, not load 
balancing is important here.


So are there any security advantage of using a Squid as a reverse proxy in 
front of my webmail ??? Because I can't see any security benefit...


Thanks a lot


Alejandro
