The Tag system allows you to mass-select either mail messages, old mail messages or news articles which you can then perform functions on them, as a whole. For example you may wish to tag an interesting news thread as well as a collection of e-mails you have received regarding the thread and save them as a plain text file to import into Microsoft Word.
Tag a message: The process of tagging is similar to that of marking mail or news items as read or unread, simply highlight the item or multi-select the items you wish to tag and press 'T'. The tag box (shown below) has been replaced in 2.20 by a drop down menu that appears at the top of the screen when one or more items have been tagged.
Resets the auto expiry flag for all tagged items.
Moves tagged mail from one mailbox to another. Select the target mailbox from the drop down menu.
