This is a post for current members and will be of interest to you if you have a firewall that is currently only allowing outbound connections to particular IP addresses.
In other words, your firewall is restricting all outbound connections except certain IP addresses that you have specified.
To get technical, we are adding new IP addresses to the DNS ‘A record’ for our SMTP service.
Like almost all of our members, if you don’t have a firewall that blocks most outgoing IP addresses, you won’t need to make any adjustments.
You will find the ranges of IPs here.
Note: the ranges are given in CIDR format. If you need the individual IP addresses, you can convert each range using this website.
We’re making these changes to offer greater reliability in the event of any issues with any one server or location. The changes will be made in the next 48 hours.
