This article will help you troubleshoot why your mail client (such as Outlook or Mac Mail) is receiving email, but unable to send email
If you can receive email but cannot send email, check your outbound server settings. Most email programs have a default outgoing port of 25, however, most Internet Service Providers (ISPs) block traffic on this port to prevent junk mail (SPAM) from being sent out on their network.
Our servers are configured to allow you to send on secure ports 587 and 465, so try changing the outgoing port to one of them before trying to sending again.
You can also check the encryption type is set to TLS/SSL which is required to connect over secure ports. Our servers also require password authentication to be enabled for your outgoing server.
Once those checks are complete, you should be able to connect to the outgoing server successfully.
If issues persist, please check you are not blocked by our firewall by visiting our Status Webpage or contact support for assistance.
