In order to use Mac OS X Mail with OKmail, you'll need to enter the following information:
Many thanks to Tom Penzer for these instructions.
Launch Mail and select 'Preferences' from the 'Mail' menu.

In the 'Preferences' window, click the 'Accounts' button and then the 'Add Account' button.

In the 'Account Information' window, select 'IMAP' for the 'Account Type:' field. Give a description for your account in the 'Description' field. For 'Email Address:' field, enter your OKmail email address. In the 'Full Name:' field, enter your name as you would like it to appear in the mails you send. In the 'Incoming Mail Server:' field, enter 'mail.messagingengine.com'. For the 'User Name:' field, again enter your email address at OKmail. Give your password in the 'Password:' field. In the 'Outgoing Mail Server:' choose the 'Add Server...' option in the popup menu.

Note: Guest users do not have access to the 'mail.messagingengine.com' SMTP server. Member, Full and Enhanced users do have access to the 'mail.messagingengine.com' SMTP server, so the following does not apply. Guest users should instead set the 'Outgoing Mail Server' field to your ISP's SMTP server. You should be able to find this information in your ISP's documentation. We don't have the information, so please don't email us asking what it is. Also, depending on the strictness of your ISP, you may also need to set the 'Email Address' field in step 3 to your ISP's email address. The only way to be sure of if this is required or not is to try and send an email, and if you get an error, try again after changing to your ISP's email address. Finally, if it still doesn't work, you should make sure that the 'Use SSL' checkbox displayed in step 4 below is NOT checked.
In the 'SMTP Server Options' window, enter ''mail.messagingengine.com'' in the 'Outgoing Mail Server' text field. If you want to use SSL for secure mail transfers, check the 'Use SSL' checkbox, and choose 'Password' in the 'Authentication' popup menu. In the 'User Name:' field, enter your full email address at OKmail and in the 'Password' field, enter your OKmail password.
Guest users using their ISP's SMTP server should make sure that the 'Use SSL' checkbox displayed above is NOT checked.
Now, select the 'Advanced' tab on the top of the 'Account Information' window. In the 'Account Directory:' field, enter '~/Library/Mail'. In the 'IMAP Path Prefix:' field, enter 'Inbox'. From the experience of some users, getting the capitalisation correct here is important. Using 'inbox' or 'INBOX' seems to cause varying levels of confusion in different versions of Mac OS X Mail, so make sure it is Inbox.

If you would like to use SSL to secure your incoming mail as well, check the 'Use SSL' checkbox, and choose 'Password' in the 'Authentication' popup menu.
The last step is to configure the special folders of the IMAP server. But first you have to retrieve the server's folder list. Click the 'OK' button of the 'Account Information' window to apply all these settings you've just configured. You can close the 'Preferences' window.
In the main viewer window, you should now have your new account showing in the bottom of the Mailboxes panel. To retrieve its folders list, just click on the new OKmail account's inbox and wait a few seconds. If the list doesn't appear when you expand the OKmail account's display in the mailboxes panel, select the account, then choose the 'Synchronize Account' option in the 'Mailbox' Menu.

Now you should see your OKmail folders in Mail.app. Select the 'Trash' folder in Mail.app and click 'Mailbox' -> 'Use Selected Mailbox For' -> 'Trash'. Repeat these steps for the 'Sent Items' folder. This will set up 'Sent Items' and 'Trash' as special folders synchronized with your OKmail account.
Your IMAP setup is now complete. You can now use Mail to access all your e-mails in your OKmail account. You can read messages, and save downloads. You can move or copy messages, either between OKmail folders, or between OKmail and local folders on your home/work machine.
Mail will use Inbox, Sent Items and Drafts in the same way as OKmail webmail. When you delete items however, they will not be deleted from the server. They will instead be moved to the Trash folder until you purge the trash folder. You can purge a folder by going to the 'Mailbox' menu and selecting 'Erase Deleted Messages'.

IMAP is a powerful protocol that allows you keep to your email synchronised, whether you're at home, at work, at a friends place or an internet cafe. You don't have to worry about what computer the email is on, because all the email is kept on the server and each client sees the same 'view' of the email. See this FAQ page to learn more about IMAP
There are currently no known troubleshooting issues with this client.
