such user <www-data@wsr.ac.at>. Unchanged since
2006-10-13T09:55:07+0200, next check 2006-10-13T09:55:07+0200 (#5.1.8)
(in reply to RCPT TO command))

    next check 2006-10-13T09:55:07+0200 is obviously wrong as it is in
    the past (looks like it is the same as the last change date).

    should be fixed in r233
