[Evolution] imap server errors when sending mail.

[Ian Perryman <iperryma altera com>]

Ever since I have started using evolution, I have had difficulty with sending mail reliably.  Sometimes the message would be mangled in my "sent" folder after being sent, sometimes it would be left in the outbox, only to be resent the next time I sent a message ( recipients would receive multiple copies).  Long delays would occur when sending before the message would be transferred from the outbox to the sent folder.

I could not find anything in the archives on this topic, so I I ran evolution as follows:
 iperryma>export CAMEL_VERBOSE_DEBUG=1
 iperryma>evolution > tmp/evolution_dump 2>&1

I am using imap with a MS Exchange Server to view my mail. I leave the mail on the server.

I use SMTP to send mail to an internal host mail server (no SSL) and no authentication.

Occasionally, I get error messages when sending mail.  A pop up window with something  like "an error occured but message was sent ok".

The message is still sitting in my "outbox" but indeed the recipients received the mail.

In the output file the following lines appear:

(evolution:5696): camel-imap-provider-WARNING **: Unexpected response from IMAP server: Subject: BAD Protocol Error: "Unidentifiable command specified"
sending : A00011 NOOP
received: From: BAD Protocol Error: "Unidentifiable command specified"

(evolution:5693): camel-imap-provider-WARNING **: Unexpected response from IMAP server: From: BAD Protocol Error: "Unidentifiable command specified"
sending : A00012 LIST "" {1+}
%

Any ideas what might be going on? This behaviour does not occur for my colleagues using Mozilla in a similar configuration.
