Calyx Point pcf files

[John Beamon]

There is a mortgage/realty software called Point, produced by Calyx,
that has a .PCF file format for its data output. These are simple
reports, not executables or macros or whatnot.
amavisd-new-20030616p10-5 from Debian Sarge sees these .PCF files
incorrectly as Windows executables.

Is there a way to exempt certain files, extensions, etc from being banned?

Hi,

Yes. Check your amavisd.conf file for the $banned_filename_re
variable. Check for the pcf in the list given there. It could
also be that the mail client sending these pcf-files puts them
in a MIME with a type banned by amavis (also handled by the
$banned_filename_re variable).

Don't forget to restart amavis after changing the configuration.

Regs,
Sven

That list is the first place I checked. The string "pcf" was not listed
in $banned_filename_re in the first place. The 'file' utility is
spotting these, not by extension, but by file type "Windows executable".
The extension is .pcf, but the mail log excerpt looks like this.

The file(1) utility does not care for a file name, it just checks the
contents. If the Calyx data output looks like a MS executable to
file(1), I'm afraid you will have to instruct the file(1), i.e. its
'magic' database, to distinguish Calyx results from true executables.

As a workaround, in newer amavisd-new versions you can place a 'permit'
rule of file NAME *.pcf BEFORE a 'block' rule for executables,
if that is acceptable.
