webmail.pair.com is a web-based email system for Pair Networks' customers. Every Pair Networks mailbox is ready to use with webmail (this includes both the mailbox that is included with every hosting account, as well as extra mailboxes that are added using the Account Control Center).
Webmail uses the Roundcube interface, an open source user interface that runs on a LAMP server. It has multilingual capabilities, plain text and HTML message compatibility, and the option to spell check messages before sending them. It also offers an address book and shared folders.
You can make changes to the Roundcube interface by going to the Settings tab in the upper right-hand corner of the interface. Here you can change the user interface, enable spell-checking, and much more.
If you want to log in to the webmail client, you can do so at webmail.pair.com.
From there, you will be able to log in to the Pair Networks affiliated mailboxes and manage your emails.
