Hello,
as you know a lot of MUAs allow user to add the attachments with non-ascii
names (koi8-r, cp1251 etc.). For example, the header of attachment made
by mutt looks like
Content-Type: application/vnd.ms-powerpoint
Content-Disposition: attachment; filename*=koi8-u''%D4%C5%D3%D4%2Epps
Content-Transfer-Encoding: base64
In such case exim isn't able to get the filename of attachment in
$mime_filename variable. Therefore such attachments cannot be catched
neither by construction:
acl_smtp_mime = acl_check_mime
[...]
acl_check_mime:
warn
message = Attachment: $mime_filename
log_message = Attachment: $mime_filename
condition = ${if
match{$mime_filename}{\N\.(bat|btm|cmd|com|cpl|dll)\N}}
nor by
acl_check_data:
deny
message = This message contains an attachment of an unwanted
type (.$found_extension)
demime = bat:btm:cmd:com:cpl:dll:lnk:msi:pif:prf:reg:scr:vbs:url
Can anybody suggest the best way to catch extensions with filename in
any charset?
Thanks a lot!
