It is possible to import e-mails to Opera’s M2 e-mail client, from earlier versions of Opera, Outlook Express, Eudora, Netscape Mail (only version 6 and 7), or any mailbox stored in the generic mbox format. Select File > Import > Mail to import your e-mail. You can import different accounts, folders, settings and contacts. When importing from Opera 6, the folder structure will be copied to My folder and the imported e-mails will be saved to the Received folder.
Quick reply is useful for chat-like conversations. You can type a short text that will be appended to the top of the original quoted message. When you are viewing a mail, type your message in the text box and click on the Quick reply button. This will send the reply to all the recipients of the original e-mail.
Set up filters for My folders and Spam by right-clicking on a folder and then Properties. Click on Add filter, Boolean operators are supported—you can match your filters by components such as Sender, To header, or Entire mail. The condition can be set to ‘Contains’, ‘Doesn’t contain’, or ‘Matches regular expression’. When you are finished with each filter, set the filters to ‘And’ if your messages must satisfy all the filter terms or ‘Or’ if they only need to match one of them.
