[Mimedefang] little changes - big troubles

[hans mayer]

hi all 

just testing with sendmail 8.12.3 and mimedefang 2.6 
in test environment. 

setting up with standard configs works great - thanks to david, we 
use md since about 1 year with success.

now changing in /etc/mail/mimedefang-filter the subroutine filter
to the following:

#****************
sub filter {
    my($entity, $fname, $ext, $type) = @_;

    if (re_match_ext($entity, '^\.(rtf|doc|xls)$')) {
        return action_accept();
    }

    return action_quarantine($entity, " attachment $fname is quarantined
\n" ) ;
}
#****************

as i want only accept some extensions ( in real life is't much more ) 
and quarantaene all others. all others unchanged.

now (after restarting) i did send a windword document with extension
.doc
( we are using netscape ) the window didn't close. after a while an 
error message opened "4.7.1 Please try again later" 

in syslog i see a lot of ( about a dozen ) of this: 
Apr  9 16:14:57 bfl-sg6 sm-mta[24522]: g39EEvIO024522:
from=<mimedefang at bfl-sg6.bfl.at>, size=1245, class=0, nrcpts=1,
msgid=<200204091414.g39EEv0p024521 at bfl-sg6.bfl.at>, proto=ESMTP,
daemon=MTA, relay=localhost [127.0.0.1]

and finaly several times: 
Apr  9 16:15:46 bfl-sg6 sm-mta[24516]: g39EEjIO024516: Milter
(mimedefang): timeout before data read

Apr  9 16:15:46 bfl-sg6 sm-mta[24516]: g39EEjIO024516: Milter: data,
reject=451 4.7.1 Please try again later
Apr  9 16:15:46 bfl-sg6 sm-mta[24516]: g39EEjIO024516:
to=<mayer at relay.bfl.at>, delay=00:01:01, pri=30351, stat=Please try
again later
also:
Apr  9 16:16:14 bfl-sg6 mimedefang[24494]: Filter did not remove
UNFINISHED file -- returning tempfail code to sendmail

in /var/spool/MIMEDefang/ ( which was empty befor ) are now several
qdir's 
and also /var/spool/mqueue and /var/spool/clientmqueue was filled up. 

is my "sub filter" so bad ? 

any ideas why my very simple filter-routine doesn't work ? 
for my understanding the changes are not very significant, but 
i am not a perl guru.

maybe somebody else can test with my config ? 
hoping for support of the reading group. 

best reagrds 
hans
