Hi

I have a client that uses courier/qmail/sqwebmail/maildrop setup on debian stable (courier-*.037.3, qmail-1.0.3). he uses the sqwebmail to configure auto-replies. for two years everything worked fine, but suddenly the auto-replies stopped working with "Unable to execute" error in the logs. he didn't change the versions of the packages, (it started before the latest security update and it continues after updating - in debian stable the version is not changed, the fix is applied to the current version). the mailfilter file generated by sqwebmail is:

--------------------------------------

#MFMAILDROP=2 # # DO NOT EDIT THIS FILE. This is an automatically generated filter.

FROM='usera@mail' import SENDER if ($SENDER ne "") { FROM=$SENDER }

##Op:islargerthan ##Header: ##Value:0 ##Folder:+Test ##From:use...@xyz.co.il ##PlainString ##Name:vacation

if (($SIZE > 0)) { AUTOREPLYFROM='use...@xyz.co.il' `/usr/bin/mailbot -A "X-Sender: $FROM" -A "From: $AUTOREPLYFROM" -m "/users/usera/Maildir/autoresponses/Test" $SENDMAIL -t -f ""` }

to "/users/usera/Maildir/."

-------------------------------------------------------------------------

when running maildrop with "-V 10" I get the following output:

---------------------------------------

when running as the user: 'cat <MESSAGE> | maildrop' the autoreply works without a problem.

does anyone has any idea what can cause this error? (I tried 3 users and the error happened with all of them).

btw, the users authentication is from an NIS server.

thanx
