Subject: Re: Getting emails with IMAP generates BadResponseError

I try it and get following output:

S: * OK IMAP4rev1 DvISE Mail Access Server MA-8.10a (0126)
C: RUBY0001 LOGIN xxx xxx

/usr/local/lib/ruby/1.8/net/imap.rb:972:in `get_tagged_response':
Protocol error: command unknown or arguments invalid
(Net::IMAP::BadResponseError)
...

There are 795 mails, this looks good, but I have no idea what is wrong?
