IMAP organizes your email messages on the mail server. Regardless of where you are when you look at your email, you will see the same messages organized the same way, even if you use different computers.
Before attempting to set up an IMAP account, make sure the email service you are using supports it. Then follow the procedure for POP and select IMAP instead of POP when asked. Do not set up an email account to use both POP and IMAP simultaneously as this is likely to cause problems. Therefore, use either POP or IMAP for each account.
When your IMAP folder has been set up, and all messages are downloaded to your computer, your IMAP folder tree appears in the "Mail" panel under "Mail for...".
The INBOX folder is the default folder for incoming messages and cannot be deleted. Click it to read your messages. Reading and sending messages over IMAP is similar to working with POP.
Go toto customize your IMAP folder tree. Click the checkboxes to select which IMAP folders you want to access from your computer.
Note that when you delete an IMAP folder from the mail server, all messages in that folder will be lost.
To move a message from one IMAP folder to another, drag the message from the message view and drop it in the new folder.
Account options are the same as for POP, with these additions:
Note: To take full advantage of IMAP capabilities, you should be connected to the Internet.
If you want to export your email messages from Opera for use with a clean Opera install or a different email client, the easiest way is to make sure all incoming message types are displayed in the Received view. Then rightCtrl-clicking it and selecting Export. Opera will then export all the messages in the selected view to a single, compressed file that is convenient for import.
Note that any view in the mail panel can be exported individually. This includes sent messages and drafts.
You can use Opera's notes feature to create message templates. Open the Notes panel and create a folder to store your templates. Add a new note and add the template for your message as the note text. Whenever you want to use this template, either select the note in the Notes panel and double-click it, or right-click a message composition window, and pick the template from the Insert note sub-menu.

You can also create message templates using drafts:

For IMAP messages, you need to download the full message content first. To do this:

Opera protects your username and password as they are sent to your mail or news server, by supporting a variety of authentication schemes. To help you easily configure your account, Opera Mail automatically tries to find the most secure authentication method your server supports. Unfortunately, this does not always work. If you are receiving authentication errors, try choosing a different authentication method for the server in the account's server properties. The authentication methods are listed in order of security, with the most secure at the top.
Authenticatation for the incoming server is set to "Auto" by default. When the Auto setting us used, the server attempts to use the most secure authentication method available first and, if it fails, tries the next most secure method until one succeeds. Authentication for the outgoing server is enabled by default, and set to "Auto". These authentication settings only control encryption of your username and password. TLS or SSL encrypts mail data, if available. Not all servers support all methods of authentication. To change these settings, see the Edit account topic.
We are always interested in improving the automatic authentication negotiation. If you run into problems that are solved by changing to another authentication method, please file a bug report (including a log of client server communication) or visit one of the relevant discussions forums.
One of the most common problems users experience when sending email is a “relay access denied” error. Many ISPs are trying to fight spam by making it more difficult for spammers to send their emails. Outgoing mail (SMTP) servers are often configured to only allow outgoing mail from users it recognizes through a process called "SMTP authenication". If you receive a “relay access denied” error, your outgoing mail server probably requires SMTP authenication to send emails. See the above troubleshooting tip for instructions to enable SMTP authentication.
Some SMTP servers do not support authentication. If you get an error message from the server when sending mail, try disabling SMTP authentication. To disable SMTP authentication, follow the steps below.
You can log the communcication between Opera Mail and the email server. If you are filing a bug report and add this log as a text file, it makes it easier for us to investigate the problem.
To activate logging for incoming mail, IMAP or NNTP (news), follow these steps:
To activate logging for outgoing mail, follow the steps below:
It is a good idea to disable logging again after the relevant information is gathered. Simply leave the "Outgoing Log File=" and "Incoming Log file=" options empty.
As an additional step to fight spam, many ISPs require you to check for new email before being able to send messages. Opera allows you to do this by queuing email, then sending it when checking for new messages. To enable this:
You can change the reply/follow-up text attribution line shown at the top of email replies and newsgroup follow-ups. An example of this is "On Wednesday, October 27, 2004, Joe Bloggs <firstname.lastname@example.org> wrote:" Use the accounts.ini setting and for email accounts, use the "Reply=" setting, while for news accounts, use "Followup=". The following is a list and description of the available parameters:
The syntax for the message-ID header sent by Opera is described below:
::time()(seconds since 19700101 000000UTC).
<op[seconds since 1970][millisecond|random][md5 of From:|random][personalization]@[idna-fqdn]>
(Semi-base36 is a function that will take modulo-36 of a number and convert this to a character where
'9'=35, and add it to the left of the already calculated string. The number is then divided by 36, and the function loops until it has given the wanted number of characters.)
There are two settings that allow you to customize your message-ID header:
Using these settings, you can easily create a label to catch all messages that you have posted to a newsgroup and any replies to those messages (as long as the replier's newsreader correctly cites your message) by labeling for any messages that contain "Personalization@FQDN" in any header. For instance, if Personalization is set to “suoc” and "FQDN" is set to "news.opera.com", create a label for “email@example.com”.
