In preparation for the release of ExchangeDefender 5.0 we’ve installed 4 new servers to process outbound mail for ExchangeDefender clients.

This transition was seamless and shouldn’t require any work from our partners, however any clients who are using SPF records will need to add the following IP addresses

p4:65.99.255.234
ip4:65.99.255.237
ip4:65.99.255.238
ip4:65.99.255.239
