just seems as if the credentials are cached somewhere still. Did you try restarting imap ?
Also it seems as if your /etc/postfix/ispcp/domains , sender-access not contain the actual data.
Can you pls take a look if info@noname.tld still exists in there ?

If you use courier for imap/pop3 they retrieve the login data from mysql - so please also check with PMA if they still exist there.
