Squid is a HTTP proxy so generally you can't access smtp/pop port through squid.

FYI Setup iptables rules to access outlook ( i never used this)

Code:

# echo "1" > /proc/sys/net/ipv4/ip_forward
# iptables -t nat -A POSTROUTING -p TCP --dport 110 -j MASQUERADE
# iptables -t nat -A POSTROUTING -p TCP --dport 25 -j MASQUERADE

squid proxy + pop3/smtp + iptables

Hi,

If you're looking for a POP3/IMAP proxy then have a look at Nginx and its documentation wiki.

Kind regards,

Eric
