We experienced a mail forwarding delay this morning that was caused by one of our internal system processes deciding to quit. The issue has been resolved and mail forwarding has been restored to full speed. This would have impacted new mail forwarding messages recieved between 10:00am and 12:00pm today.
Update: We have new reports that this issue was also taking place during the evening yesterday but we have as of yet been unable to verify the length or severity of that particular malfunction. In any event the problem has been corrected and mail flow is presently working as expected.
