I specifically said 're-attach'. I did not say 'append in plain text'. I'd love to see an end user get base64 into an executable to infect themselves from an appended bounce message. When I send something via exchange somewhere that 550's my mail, I get a generic message generated by exchange stating ""Your message did not reach some or all of the intended recipients.". I tested Exchange -> Qmail, and Exchange -> Exchange, and Exchange -> Qmail Gateway -> Exchange When I send something via Mozilla using a qmail gateway, I get an appended bounce returned... Nothing I work with seems to mis-behave. That is why I asked. d ------------------------------------------------------- This SF.Net email is sponsored by: SourceForge.net Broadband Sign-up now for SourceForge Broadband and get the fastest 6.0/768 connection for only $19.95/mo for the first 3 months! http://ads.osdn.com/?ad_id%62&alloc_ida84&op=click _______________________________________________ Qmail-scanner-general mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/qmail-scanner-general
