mimecheck boundary [file]mimezip boundary [file]
mimebzip boundary [file]
mimegzip boundary [file]
DESCRIPTION
The scripts mimecheck, mimezip, mimebzip, and mimegzip can be used to determine the contents of MIME encoded attachments of the type application/octet-stream. The scripts require the boundary as provided in the headers and/or bodys of mails with enclosed attachments. The scripts read from standard input if no file was provided and write out the detected MIME type to standard out.EXAMPLE
A short filter rule used by procmail(1) to check for DOS executables in MIME encoded zip archives found in many attachments:BLANK="[ ]+" TYPE="${BLANK}multipart/(alternative|mixed)" :0 * $ ^Content-Type:${TYPE};(${BLANK}|$)*boundary=[\"']?/[^ \"';]+ { BOUNDARY="${MATCH}" TYPE="" :0 B * $ ^Content-Transfer-Encoding:${BLANK}base64 { TYPE=`mimecheck ${BOUNDARY}` :0 * TYPE ?? application/x-zip { TYPE=`mimezip ${BOUNDARY}` } } :0 * TYPE ?? executable.*DOS * TYPE ?? DOS.*executable /dev/null }
there is no guarantee that this piece of a procmailrc(5) file will work.
