Opera Mail (formerly known as M2) is the

Atom and RSS

feeds.

Opera Mail uses one database that keeps an index of all mail and sorts the messages automatically into several "views" or access points. Messages are automatically sorted by types, such as mailing lists, and mail with attachments. This approach to indexing allows for quicker access to messages. For instance, a message sent to a mailing list with a word document attached will appear in both the "Documents" attachment view and in the "Mailing lists" view. Opera Mail can also use Bayesian filtering to automatically sort messages into other views. All messages in the database are accessed by opening the "Received" view.

The integrated mail component included a simple

IRC client, but this is no longer present in the standalone program. The IRC client supported multiple servers, file transfers, and interface customization through CSS

.

Opera Mail can display text and

Presto layout engine

to display HTML.

Opera Mail is at the end-of-life stage of its product lifecycle; this means neither technical support nor product and security updates will be provided. The product is no longer available for download. Users of Opera Mail who have large amounts of email and would like to utilize 64-bit performance can use the 64-bit build of the Opera Web Browser, which is the same code contained in the standalone email client. ^[citation needed]
