I have a simple script based on perlfilter-example.pl that looks for msgs w/ attachments named *.scr, or *.pif (guess what for).

My differences (quotes and no-quotes around name of file):

return "500 Invalid attachment." if $line =~ /filename=".*\.(pif|scr)"$/i;

return "500 Invalid attachment." if $line =~ /filename=.*\.(pif|scr)/i;

It doesn't work, as I am able to pass messages w/ pif attachments w/o a problem. 'enablefiltering' contaings: esmtp local

It works when I bolt up to port 25 using telnet and manually try to send a SoBIG msg too it.. ie:

rcpt to:<us...@somedomain.com> 250 Ok. data 354 Ok. From: Pamh...@web30a.com To: us...@domain.com Subject: Your details Date: Tue, 26 Aug 2003 0:19:13 --0500 Importance: Normal MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="_NextPart_000_07498D55"

This is a multipart message in MIME format

--_NextPart_000_07498D55 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit

Please see the attached file for details. --_NextPart_000_07498D55 Content-Type: application/octet-stream; name="thank_you.pif" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="thank_you.pif"
