If a mail with image attachment[0] is sent I get '(!!)SA failed: error closing
input file: Bad file descriptor at
/usr/share/perl5/Mail/SpamAssassin/Message.pm line 569, <GEN35> line 183. at
(eval 113) line 759, <GEN35> line 183.' in syslog,
worse, if the error occurs, the mail is rated as not being spam.
The trigger seems to be the Content-Type: header of the attachment. If set to
"image/jpg" "image/gif" "image/png" the error occurs, if set to "text/plain" or
"text/html" it's gone.
I just upgraded from squeeze which showed the same effect. Running "spamc" or
"spamassassin -t" does not produce this error.

I feed it to swaks(1) for delivery to the mail server.
I also tried debugging options on with
/etc/amavis/conf.d/000-local:
$sa_debug = 1; # Enable SpamAssassin debugging
$log_level = 5; # (defaults to 0)
this leads to extensive output /without/ the initial error message concerning
the file handle (this might be an indicator to a race condition, maybe)
If I take a look at the code as indicated by the error message, I'm quite not
sure what would be the point of aborting
after an unsuccessful close() here.
