RE: [squid-users] Squid blocks mail traffic??

iptables -A FORWARD -p tcp -m tcp -m multiport -o <your_outside_if> -j
ACCEPT --dports 25,110,465,995

Replace <your_outside_if> with whatever is appropriate for you system.
This will forward all pop and smtp traffic to your outside interface.
You may remove ports 465 and 995 if you like. They allow ssl traffic
to gmail. Make sure your email clients are not using the proxy
settings, but are configured normally.
