This doesn't work for me:

# iptables -A INPUT -p tcp --dports 110,143,993,995 -j ACCEPT

iptables v1.4.7: unknown option `--dports'
Try `iptables -h' or 'iptables --help' for more information.

However in the man page, there is an option --dports... any ideas?

    Quick guess would be that you need to use the multiport module: -m multiport --dports 110,143,993,995 ...

You have to use --match multiport in the rule for defining more ports

#iptables -A INPUT -p tcp  --match multiport --dports 110,143,993,995 -j ACCEPT

You need to specify the -m multiport module before using the dports options
