I need to configure Exim to quarantine emails that have media
attachments over 1.5MB that do not also have PDF or DOC attachments.
In the mime acl, there is this...
# This variable set to 1 means skip large size limit test
warn set acl_m6 = 0
# This variable set to 1 means the email attachment is large
size multimedia
warn set acl_m7 = 0
# Pretty good attachments that we can skip size limits
accept condition = ${if
match{${lc:$mime_filename}}{\N(?>.*)(?<=pdf|doc)$\N}{1}{0}}
set acl_m6 = 1
# Quarantine media greater than 1.5 MB
warn condition = ${if >{$message_size}{1536k}{1}{0}}
condition = ${if
match{${lc:$mime_filename}}{\N^(?>.*)(?<=jpg|jpeg|pps|ppt|gif|png|wmv|mpg|mp3|mpeg|avi|wav|bmp|mov|asf|asx)\N}{1}{0}}
set acl_m7 = 1
In the routers, there is this one....
# Email with large media attachment are quarantined
large_media:
driver = accept
condition = ${if and { \
{ eq{$acl_m6}{0}{1}} \
{ eq{$acl_m7}{1}{1}} \
{! def:h_X-MedQuar:} \
}{1}{0}}
headers_add = X-MedQuar: True
transport = large_media_mail
This router is bypassed completely. Aren't acl variables available
during router time?
Thanks,
Craig Jackson
