Based on Simon Josefssons reply on another list, see below, I suggest
the attached patch.

BTW, is it ok to use strcasecmp(3) just like that?

I believe this is a bug in those servers, see RFC 3501 and in
particular the last sentence of quoted text below.  [...]

9.      Formal Syntax

   The following syntax specification uses the Augmented Backus-Naur
   Form (ABNF) notation as specified in [ABNF].

   In the case of alternative or optional rules in which a later rule
   overlaps an earlier rule, the rule which is listed earlier MUST take
   priority.  For example, "\Seen" when parsed as a flag is the \Seen
   flag name and not a flag-extension, even though "\Seen" can be parsed
   as a flag-extension.  Some, but not all, instances of this rule are
   noted below.

        Note: [ABNF] rules MUST be followed strictly; in
        particular:

        (1) Except as noted otherwise, all alphabetic characters
        are case-insensitive.  The use of upper or lower case
        characters to define token strings is for editorial clarity
        only.  Implementations MUST accept these strings in a
        case-insensitive fashion.
