--- Comment #13 from Thomas Arend <tho...@arend-rhb.de> --- A first quick and dirty solution to work around this problem was encouraging. I converted the kmail2 mbox with the following command to the older version: sed '/^From / s#\(...\), \([0-3][0-9]\) \(...\) 2012 \([0-2][0-9]:[0-5][0-9]:[0-5][0-9]\) [+-][0-9]\{4\}#\1 \3 \2 \4 2012#' <spam-old.mbox >spam-new.mbox sa-learn reported: Learned tokens from 1489 message(s) (1733 message(s) examined) Which may be ok some messages may be learned earlier. A trailing "0" in the day - which may not comply to ctime format - does not effect the parsing of the mbox file. This work-araound will help me over the next days and weeks. But learning in kmail2 may not work or will need a modification. I understand that there are different definitions for the date time in the "From_" line. What a mess! I agree that the best would be to persuade the kmail folks to back off the change.
