Currently our easySMTP mailout system is being rate limited when sending to domains using protection.outlook.com mailservers which is causing substantial delays.
We have a request in progress with the provider to resolve the issue and have taken steps within our own network to try to alleviate it but there may be delays for some time.
If you are experiencing problems with this, please send through mailout.easymail.ca instead of mailout.easydns.com and your email should go through without difficulty. The same authentication information will work at the easymail.ca host all you need to do is change the hostname you are using to send email.
We apologise for any inconvenience.
