Or masquerade all traffic to the new server with firewall rules:

iptables -t nat -A PREROUTING -i ethX -p tcp -m tcp --dport 143 -j DNAT
--to-destination 1.1.1.1

iptables -t nat -A POSTROUTING -d 1.1.1.1/32 -p tcp -m tcp --dport 143 -j
MASQUERADE

ethX --> interface where connections come from
1.1.1.1 --> new server IP address

Maybe smth is wrong up there, didnt tested, but I think its cool.


cheers.
