Wow ! Thank you so much Mike and Kyle, it work great now !
Here what I do to fix my vacation program:
I take "autorespond-2.0.5.tar.gz" from Mike's link and extract the files.
I check in "autorespond.c" at line 696 "AUTORESPOND: too many received
from", the exit code was (0). (Good !)
Compile autorespond !
# cd /your/path/to/extract/file/
# make
And simply replace the binary in "/usr/local/bin/" by the new one.
Restart Qmail properly.
My message have proper "end msg" signal now:
2013-07-31 09:53:17.611352500 new msg 220574
