Hi everyone,
/etc/postfix/header_checks.pcre:
/^Content-(Disposition|Type).*name\s*=\s*"?([^;]*(\.|=2E)(
ade|adp|asp|bas|bat|chm|cmd|com|cpl|crt|dll|exe| hlp|ht[at]|

vb[esx]?|vxd|ws[cfh]))(\?=)?"?\s*(;|$)/x REJECT Attachment name "$2" may not
end with ".$4"
the codes define what kind of attachment can not be received by server, you
have to add one by one.
HOW can we just receive just such as .jpg .png .mp4 and reject all other
attachment in a short regexp to do the job?
thanks.
yours.
