Email Delay
April 6, 2012

Toward the end of last week, we were experiencing some email delays in our system. This was caused by two main reasons. The first is that we have moved all clients to the new mail servers, causing the new server load to peak higher than we had expected. The other is that, in order to process more email, we modified the email preprocessing system which handles SPAM filtering, email forwarding, auto reply, and mailing lists to be faster, thus delivering more email than the email servers could handle.

From last Friday, we have been rewriting our software to improve mail processing performance. Because of the changes we made, we have not seen any delays since last weekend. We have been working to make our email servers process more email all this week as well, and we estimate that over the past week our email servers have become three times faster. Although we should have done this earlier, I am happy to announce that we no longer detecting any email slowdowns.

We were able to solve the email delay problem by rewriting the software itself. That is something other hosting companies, who do not have an in-house software development team like ours, cannot do. We are constantly making our software faster, more efficient, and more reliable. If you have any questions or concerns about our email hosting, please feel free to contact us.
