Just to let our spam filtering clients know that next week we are upgrading our servers again, (yes i know a pain in the ass but hey it’s for your benefit!) These new servers will mean new IP addresses and so we are informing you that you can update your firewall rules with the following IP addresses for our servers.
To do this you need to block all SMTP transactions from outside the following:
Filter 4: 18.104.22.168 to 254
Filter 5: 22.214.171.124 to 92
Filter 6: 126.96.36.199 to 55
Your network manager will know what to do with these, If is important that you take action on these firewall changes before Tuesday 26th January 2010.
