NoSpamToday - IMAP login failed

[dbanalyst]

I have running a batch file (to teach it what is spam) using the IMAP2Mbox.exe process for a long time now and it always worked smoothly. Recently, I started getting the following error message:

IMAP login failed: 1 NO A required privilege is not held by the client

Attached are the contents of the batch file I use and the spam.cfg file.

del spam.mbox

echo *===* >> spam.log

imap2mbox.exe --mbox=spam.mbox --folder=SPAM --config=spam.cfg --username="DOLAN/ksteutermann/ksteutermann" --pass="*.*.*.*.*" --server=DOLANPDC.dolan.compdatasurvey.com --path="Public Folders/" --debug --verbose >> spam.log

if exist spam.mbox sa\sa-learn -C sa\ruleset --showdots --spam --mbox spam.mbox >> spam.log

sa\sa-learn -C sa\ruleset --showdots --force-expire >> spam.log

sa\spamassassin -x -C sa\ruleset --lint >> spam.log
