UnityMail is a small Launcher-based mail-alert app for Ubuntu 11.04 capable of displaying the number of unread messages in your inbox.
UnityMail also has Unity Quicklist support, with a menu containing easy links for composing new messages and accessing your inbox by right-clicking on the launcher icon.
Account configuration & security concerns
UnityMail works with GMail or any other IMAP-supported webmail account. It also supports the use of multiple accounts.
Accounts are added to UnityMail by editing a hidden configuration file in your Home folder – ./config/unity-mail.conf – with a text editor, adding your account username, password and server address.

UnityMail is currently in Beta, so if you’re tempted to try it out do expect bugs. UnityMail is available for Ubuntu 11.04 only and can be installed from the developer’s PPA:
