IMAP does not update it's Folder status
<p>I want to read E-Mails from an IMAP-Server with curl (BashScript, which is using curl). </p>

<p>My problem is: After moving an E-Mail the IMAP-Server does not update, so that, if I examine the inbox, the IMAP Server shows me the old amount of messages, containing in the INBOX.</p>

<p>To clear my problem, here is some example-Code:</p>

<pre><code>function delete_mail_id() {
     curl --insecure \
          --url "${SERVER}/INBOX" \
          --user "${USER}:${PASSWD}" \
          -X "STORE ${1} +Flags \Deleted" 1&gt;/dev/null 2&gt;/dev/null
}
function copy_mail_id_to() {
    curl --insecure \
         --url "${SERVER}/INBOX;UID=${1}" \
         --user "${USER}:${PASSWD}" \
         -X "COPY ${1} INBOX/${2}" 1&gt;/dev/null 2&gt;/dev/null
}
function move_mail_id_to() {
    copy_mail_id_to "${1}" "${2}"
    delete_mail_id "${1}"
}
function wait_for_mail_move(){
    TEMP=$( tempfile )
    while true; do
        fetch_first_mail &gt; $TEMP
        if [ "$( grep 'Message-ID:' $TEMP )" != "${1}" ]; then
            break
        else
            sleep 1
        fi
    done
    rm $TEMP
}
</code></pre>

<p>Now after moving an E-Mail I wait for the mail to move, but it seems to be an endless loop. Now the funny part: If I look the mails manually through my webmailer the loop ends and the mails are moved one by one (I have a loop, so all the mails should be sorted in other Folders).</p>

<p>Somehow the IMAP only moves the Mails if I check it through the webmailer, but doesn't do it, if I don't check it. This should be automated, so, can anyone explain to me, why this is happening and what I can do about it?</p>
