Here are some screenshots for the new mail portlet. You can check out jerry's post on how to install the mail portlet. It is as simple as clicking around in the plugins installer. The mail portlet that I am using is running on the latest 5.1.x branch so you may notice some slight ui changes in the portal, but the mail portlet is the same.
For now, the initial screen is very simple. It gives you the options to either check your mail or configure your email accounts.
Account Configuration Screen:
This is the configuration window. You can customize pre-configured accounts. You can add and remove whatever accounts you want. If you want to add remove the pre-configured Gmail account, add others and modify whatever from the portlet.properties file inside the portlet.
Note: after you add your account, you may have to wait a few minutes before your first page of emails is retrieved. Some technical details behind the process is.. It will grab a list of the folders, then grab the first page of each folder, then go back for the second page of each folder.. etc.
Viewing your mail folders:
Notice at the top left, there is a drop down list. That list contains all your configured mail accounts. You can switch between accounts by selecting a different account from the list.
Reading a message:
You can view your email in plaintext or html, whichever is provided by the sender.
Note: This email is an add from alienware (and windows vista). im not a fan of either.. and i dont own any alienware stuff and neither do i run vista.. but the email looked cool.. so im using it for the screenshot : ) In case you are curious.. at Liferay we have all kinds of machines going.. apple, dell, hp.. no alienware : ) at least not that i know of.
Replying to a message:
When replying to a message, you are provided with a full wysiwig editor. The editor used in this screenshot is "tinymcesimple" which can be configured from portal.properties. The mail portlet will currently use the default editor from the properties file.
Hope that gets you to want to give the mail portlet a try. suggestions, code fixes and improvements are totally welcome : )
