When setting up a client e-mail program to retrieve user's e-mail, the e-mail account name entered for all users should be in the form of: usernamer@domainname.com
The only exception is the main (admin) account for your web site. The reason for this is that most web sites on Paravel Solutions is on shared servers, and including the domain name with the username is the only way to make the e-mail account unique.
Firewall: If you are trying to use Web Mail from your work site, and get a connection refused, your company may have a firewall in place that is blocking port 2095. Contact your company's network administrator for options.
