SPAM Attack

Recently the amount of spam that we have experienced on our servers has sky-rocked to the point of slowing down delivery or legitimate email.

We have taken the following actions to curb the influx of spam and reduce the load on our spam filters:

1. Changed the SMTP port from 25 to 587. (Notifications were sent out with instructions for making this change to your email client.)

2. Added additional RBL (Real-time Black List) lists to check mail against.

3. Once mail has been blocked by the RBLs that we have implimented, we are then blocking those offending IP addresses at our server to reduce the load off of our spam filters.

This should help to return delivery back to normal as we fine tune and tweak the new settings. As with all technology, it is not perfect. If you experience any problem receiving email from a sender you know is legitimate, let us know and we will see if it is the result of any blocking we are doing, and then make the necessary adjustments to allow that sender's email to bypass our spam checking.

Additionally, it is a good practice to add all of the important email addresses to your white-list on our server. This will assure that those addresses bypass filtering and assure their delivery.
