Mail
This section of cPanel will allow a user to accomplish many tasks dealing with the mail on an account. Anything from setting up Email accounts, to setting auto-responders can be accomplished in this area. We’ll go over each area in this section and explain its uses.
Webmail
The web mail section of the main section “Mail” is where a user can check their email through a web GUI “Graphical User Interface”. Most users prefer this type of mail client because it’s simple to use and very easy and quick to setup. Most servers already have at least one web mail client setup, in some cases there are more.
Email Domain Forwarding
An email domain forwarder redirects all email coming in on a specific domain name to another domain name. For example if we setup dot.com to redirect to dot.net, all email coming in on dot.com will redirect to its corresponding user on dot.net. (mike@dot.com redirects to mike@dot.net). Any pop accounts setup under each domain name will not be affected by this forwarding option.
Manage/Add/Remove Accounts
This section of the main section “Mail” will be one of the most used sections. This section is the heart of all Email and this section is used to add, remove and manage any aspect of any Email account.
The first things a user will see are all the Email accounts present on their account, starting with the email address, then the login name for that email address followed by a few other options.
- The first option a user has is to delete an account. This is a very simple step, simply click on delete and confirm account deletion.
- Users can easily access a web mail account simply by clicking on this button. The default web mail client will be loaded and the user name will automatically be loaded in the user name field. All that is needed next is a password.
The aging section is used to determine when the server should delete email that has already been read. If a user opts to leave their messages on a server and not allow
their email client to delete them, they will build up over time and consume a large amount of disk space. Users can use this option to keep regular maintenance on their email accounts.
Users have the option to change the amount of disk space that is allocated to each account. The default is 10MB and users can change this value when setting up an account or with this option.
Users can use this option to change a password used for each account. The old password is needed in order to complete the process.
This setting is used to automatically configure Outlook or Outlook Express to work with the corresponding Email address. This is a “quick” configuration meaning it will not assign custom names or settings within Outlook, simple configure it to check the corresponding Email address.
Add Account
There is only one other option that can be used on this page and that is adding an account. This is the section where a user can add accounts for their domain names. All domain names present on the users account are present here and can be used to setup Email accounts for any domain name. 
E-mail: Simply specify what name should be used for the Email address. Also in this section a user can choose a domain name to use.
Password: Choose a password to use for this account.
Quota: This will allow a user to decide how much disk space to allocate to this Email account. This is optional as the default is 10MB.
Default Address
In this section a user can specify what the default Email address will be. The default Email address is used to receive all email that is sent to account that are non-existing. For example if someone sent an email to mike@webmasterstop.com and used mik@webmasterstop.com, forgetting the e on Mike, it would send that email to the default email address. This is useful as no Email can be lost using this.
Autoresponders
Auto responders are setup to be used to automatically respond to an email that has been sent to the corresponding email address. Auto responders are very useful for people that are going away for a long period of time and wouldn’t be able to answer their emails. An auto responder can be setup to respond to incoming emails with any message specified by the user.
E-Mail Filtering
Email filters can easily be setup so users can manage incoming email address. These are very similar to the way Outlook uses filters. Filters are very useful for webmasters with large amounts of spam coming. If Spam Assassin is installed and operational, a custom filter can be setup to automatically delete all email that Spam Assassin deems as spam.
There is also a testing section, to test filters that have been added. Just simply fill out the required information and hit “Test Filter”. It will then display how the message will be affected by the new filters that have just been put into place.
Forwarders
Forwarders are used to direct an email address to another email address or location on the server. This is useful for users that want to direct old email accounts to new email address. Forwarders are very easy to setup, just a few simple steps.
Mailing Lists
This section of the Mail section is used to setup mailing lists. Mailing lists are extremely useful for large sites wanting to email a large number of users at once. It can also be
useful for hosting companies or other companies where customers need to be updated on new services or products.
Simply input the mailing lists name, a password to use for it and the domain name that it will be used on and hit create. That’s it, that simple. Once a mailing list is setup, email address can be added to it through this same section. There are a lot of scripts available to manage mailing lists easier, there is also a free one that comes with cPanel, check under the scripts section.
Spam Assassin
Spam Assassin is a free program that comes with all cPanel and WHM installations. It’s used to filter out incoming email on a server side basis. Meaning it’s sorted through as it comes into the server. If this is available to a user, they are able to activate or deactivate it from this section. There is also a Spam Assassin Spam Box that can be enabled also. Meaning that all email that Spam Assassin deems as spam, will be forwarded to this box and can be viewed by the user at a later date.
Trace an Email Address
Tracing an email address is similar to running a trace route on a user’s computer. It will basically map out the paths that an email takes to get to the server. This information can be useful in finding out where an email be getting lost. This information is also very interesting as it will show the complete path from the server to the email address.
