server would be proxied to the newer one automatically ?
Any additional software or only a configuration change is required ?
Return from passdb, 'proxy host=your-new-host port=143 ssl=starttls'
Aki
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.
