Hi! I have tryed "Frank DENIS" patch to truncate bounce messages ( http://qmail.hypergrid.it/www.jedi.claranet.fr/qmail-bounce.patch ), but it isn't work.
In bounce I have always only one line (Return-Path) after: --- Below this line is a copy of the message I have set 0 or 1000000 to /var/qmail/control/bouncemaxbytes without any good result. Thanks!
