Our email server had been getting older and had been slowing down appreciably. Because of this we have now upgraded our email server to a new server and operating system.
Some of the benefits are as follows:
1) Email system is running much faster and at a higher overall performance level.
2) Webmail, which was extremely slow on the old system (painfully so), is now running well, functioning as it should be.
3) We are able to run the newer versions of anti-spam software that we use (these versions of the software were not supported on the previous server). These newer versions have some features that we believe will help us to reduce the amount of spam mail customers receive.
