Client issues and configuration

It seems to be quite difficult to implement a working IMAP client. Best Practices for Implementing an IMAP Client tries to help you with it.

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

Outlook Express 6

Netscape 4.x

Netscape Mail

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

Evolution

Mulberry

Seems to be OK.

Thunderbird

Mutt

Pine

Seems to be OK.

SquirrelMail

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. Can also read mailbox quota via the getquotaroot IMAP command.
