Client issues and configuration
===============================

It seems to be quite difficult to implement a working IMAP client. Best
Practices for Implementing an IMAP Client
[http://www.imapwiki.org/ClientImplementation] tries to help you with it.

 1. Client issues and configuration
     1. Apple Mail.app
     2. Outlook
     3. Outlook Express 6
     4. Netscape 4.x
     5. Netscape Mail
     6. Evolution
     7. Mulberry
     8. Thunderbird
     9. Mutt
     10. Pine
     11. SquirrelMail
     12. Horde IMP
     13. RoundCube Webmail
     14. @Mail Webmail

Apple Mail.app
--------------

On Mac OS X Leopard 10.5 Mail.app appears to support subscribe/unsubscribe by
right clicking on a mailbox, selecting 'Get Account Info' and selecting
'Subscription List' from tabs. This however doesn't really work with any IMAP
server.

Outlook
-------

 * You should enable 'outlook-idle' workaround with IMAP.
 * You should enable 'outlook-no-nuls' workaround with POP3.
 * Outlook 2003 has problems with older Dovecot's default POP3 UIDL format,
   which causes it to download the same mails over and over again if "leave
   mails to server" option is enabled. See 'pop3_uidl_format' setting.

Outlook Express 6
-----------------

 * Using "Headers only" synchronization is buggy and can cause "Message is no
   longer available on this server" error when opening a mail. This isn't
   Dovecot specific problem, and I'm not aware of any possible workarounds at
   the moment for this in server side.
 * You should enable 'outlook-idle' and 'delay-newmail' workarounds for IMAP.
 * You should enable 'outlook-no-nuls' and 'oe-ns-eoh' workarounds for POP3.

Netscape 4.x
------------

 * You should enable 'netscape-eoh' workaround with IMAP, if you still care
   about supporting this..

Netscape Mail
-------------

I'm not actually sure what version exactly this refers to.

 * You should enable 'oe-ns-eoh' workaround for POP3.

Evolution
---------

 * Some versions don't support creating subfolders with mbox format. Evolution
   in Ubuntu Gutsy, 2.12.0-0ubuntu5, does support creating subfolders, at least
   when the parent folder is empty.

Mulberry
--------

Seems to be OK.

Thunderbird
-----------

 * If you're using <mbox> [MailboxFormat.mbox.txt] or <dbox>
   [MailboxFormat.dbox.txt],
    * You should enable 'tb-extra-mailbox-sep' workaround for IMAP. Bug report
      [https://bugzilla.mozilla.org/show_bug.cgi?id=29926].
    * You'll have to disable "Server supports folders that contain sub-folders
      and messages" setting from Thunderbird.Enhancement request
      [https://bugzilla.mozilla.org/show_bug.cgi?id=284933].

Mutt
----

 * New mutt versions supporting IDLE command will hang with Dovecot versions
   earlier than v1.0beta3. Upgrade Dovecot or disable IDLE by setting
   imap_idle=no in .muttrc.
 * <Using mutt with IMAP> [mutt.txt]

Pine
----

Seems to be OK.

SquirrelMail
------------

 * Configuration asks IMAP server name for some workarounds. There has been a
   Dovecot option since 1.4.6 and 1.5.1. For olderSquirrelMail versions, select
   the "other" option and remove the default INBOX-prefix.

Horde IMP
---------

Dovecot doesn't want any folder prefix, but leaving it empty in login screen
will just use the default. So, change the default from
'/etc/imp3/servers.conf'. Search for ''folders' => 'mail/'' and remove the
'mail/' part. For IMP2 edit 'defaults.php3', search for '$default->folders =
'mail/';' and remove the 'mail/' part.

RoundCube Webmail
-----------------

Works fine.

@Mail Webmail
-------------

Uses the namespace returned via Dovecot, full support via IMAP/POP3 using @Mail
[http://atmail.com/]. Can also read mailbox quota via the getquotaroot IMAP
command.
