Dear Arnt,
The client, which was developed with IMAP4(rfc1730), wants to connect to the UW IMAP server (supports IMAPver4rev1). In this case server has to support a command like PARTIAL(even it is obsleted).
That's fairly easy: Either you can download a ten-year-old version of UW imapd, or you can update your client to today's IMAP version.
In my observation I found that UW IMAP server is not supporting this command. I want to know about IMAPver4rev1 compatibility with IMAP4.
RFC 2060 page 77 lists the differences between IMAP4 and IMAP4rev1. RFC 2062 lists the obsolete syntax in detail.
