Update 7:07 MT Nov 24 - The issues have now been fixed and email should be flowing again. Please contact us by phone/chat/email if you are still having problems.

We are currently experiencing issues on one of our proxy servers, which our Ops team is in the middle of fixing as we speak. This might cause some of your emails to be deferred with the "Internal server error" message. All these deferred emails are being queued, and they will be sent out once the issue issue is resolved.

We apologize for any inconvenience this is causing you and appreciate your patience on this matter.
