Webmail is a great feature offered by cPanel. You can access email from any PC connected to the Internet. There are two ways to log into the default webmail. 1) Type the following information into the browser. 

If the domain name has propagated type: 
http://www.avalonmis.net/webmail 
or 
http://webmail.avalonmis.net 

2) You can also access it by going through the default webmail port number of 2095 as in the following example. 

If the domain has propagated type: 
http://www.avalonmis.net:2095 

Once you go to the address above, you will be prompted for your user name and password. Be aware, it is not asking you for your cPanel user name and password. All email account user names look just like the email address. 

In the user name section, type your full e-mail address. (Example: you@yoursite.com) 
In the password section, provide the password which you provided when you created the email account. Then hit enter. 
You are now logged into webmail.
