Getting emails with IMAP generates BadResponseError

ruby-talk
1

Hi,

I have a problem with getting emails from a special account when I will
try to get the emails via IMAP (no SSL).
Here is an example code:

imap = Net::IMAP.new('imaphost')
imap.login('user', 'pw')
imap.examine('INBOX')
imap.search("ALL").each do |message_id|
...
end
imap.logout
imap.disconnect

This works fine with other accounts!
The error occurred in line with imap.search:

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

My Ruby version is: 1.8.2 (2004-12-25) [i686-linux]

A "puts imap.capability" on a "good" account shows me:
IMAP4
IMAP4REV1
IDLE
AUTH=LOGIN
AUTH=CRAM-MD5
UNSELECT
LITERAL+

For the account with the error I get only:
IMAP4REV1

I don't know if this could help, I am not an expert in IMAP.
I hope someone can help.

Thanks.

this is bascially telling you the server does nothing for this accnt... which
seems odd.

try adding this to the beginning of your script

   Net::IMAP::debug = true

and seeing if it gives you more information.

I try it and get following output:

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

...

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