Email boxes do fill up. Servers do not want infinite amounts of mail on their hard drives, so they will lock or stop receiving mail once they hit their quota.
Problems and Solutions.
Virus – Bad Coding – Server issues
It is possible to have virus, bad code, or server issues preventing your email box from receiving mail. This does not happen often. You would probably not be able to pull your email down, thus you should notice a failure warning. Solution: contact your email provider to trouble shoot.
Not Deleting Email from the Server
This is by far the most common problem when we get email bouncing back. Microsoft Outlook and Outlook Express has a setting that allows you to “leave a copy” on the server, after you have pulled it down to your computer. The parallel to this is, going to your P.O. Box, making a Xerox of your mail, putting the mail back in the P.O. Box and taking the copies home. Eventually your email box is full.
The solution is simple, don’t turn on the “leave a copy on the server”.
Checking your “Live” email, online.
For the most part, our clients use one of two email services. In both cases, you can go online and check the live email to see if the box is full.
For Everyone.net customers, you should have a link to your online mail, something like
http://companyname.mail.everyone.net. (ask us if you do not know.)
If you are using our RedFusion Media Hosting, you may have our WildWest email service, you can log in here.

For years our biggest customer service problems have been generated by customers email issues. For the last few years, those problems have almost gone away with our use of Everyone.net email for our clients. We still get a number of questions about new accounts and setting up unusual email programs.
