I am currently trying to block MIME attachments based on their filename.
deny set acl_m3 = ${lookup {$mime_filename} nwildlsearch \
{/etc/exim4/list-filenames-reject}}
condition = ${if def:acl_m3}
message = This message containes a blacklisted attachment filename
log_message = DENY: reject_filename ($mime_filename)
warn log_message = DEBUG: acl_check_mime done for \"$mime_filename\" \
(lookup = $acl_m3)
condition = ${if def:mime_filename}
Content of /etc/exim4/list-filenames-reject (without leading spaces):
^Update-.+-x86\.zip
For an attachment named Update-abc-x86.zip the debug message is written
to the log but the deny condition isn't met.
Warning: DEBUG: acl_check_mime done for "Update-abc-x86.zip" (lookup = )
What am i missing?
