I have just seen this same error with a different configuration.

Running Thunderbird 1.0.2 on OSX 10.4.1, connecting to a single user account on
a Courier-IMAP server using SSL (but on a non-standard port due to firewall
settings):

I get this pop-up error window:  "This mail server is not an IMAP4 mail server."

(and I can't get any mail)

I know that the server is working fine.  I can connect to it using the same
settings on other mail clients such as mutt.

I found the error code on
http://www.mozilla.org/docs/l10n/l10nkits/client/windows/docs/nav40/allxpstr.h

as:

ResDef(MK_MSG_IMAP_SERVER_NOT_IMAP4,                -464,
       "This mail server is not an IMAP4 mail server.")

This is a showstopper for me and means that I cannot use Thunderbird at all.

I tracked this down via

nsImapCore.h and nsImapProtocol.cpp

It turned out to be a misconfigured server returning a malformed CAPABILITY
response.  Fixing the server configuration made the error go away.

so the server was returning illegal syntax? Marking invalid on that understanding.
