Your iptables setting is making the problem here. If you are using MASQUERADE with POSTROUTING chains on nat table you have to
specify the --to-ports option.

Set your ip-tables as,

# POP Requests
/sbin/iptables -t nat -A POSTROUTING -o eth1 -p tcp -dport smtp -s 192.168.0.0/24 -j MASQUERADE

# SMTP Requests
/sbin/iptables -t nat -A POSTROUTING -o eth1 -p tcp -dport 110 -s 192.168.0.0/24 -j MASQUERADE

Check /etc/services file as,
smtp 25/tcp # Simple Mail Transfer Protocol
pop3 110/tcp pop-3 # Post Office Protocol - Version 3

See more here at, http://squid.visolve.com/squid/trans_caching.htm and iptables manpage (MASQUERADE part)
