Hi
I've found a way to log the attachments, but only those, were the suffix has
3 letters like .xls, .exe ... but not those like .vb or .x (2 or only 1 letter)
My system_filter entry looks like:
if $received_protocol is not "scanned-ok" and $received_protocol is not "spam-scanned" and $message_body matches "(?:Content-(?:Type:(?>\\\\s*)[\\\\w-]+/[\\\\w-]+|Disposition:(?>\\\\s*)attachment);(?>\\\\s*)(?:file)?name=|begin(?>\\\\s+)[0-7]{3,4}(?>\\\\s+))(\"[^\"]+\\\\.(?:[...])\")[\\\\s;]"
# ^^^
then
logfile /var/log/exim/attachments.log 0644
logwrite "$tod_log $message_id has attachment : ($1)"
logwrite "$tod_log subject : $rheader_subject"
logwrite "$tod_log recipients : $recipients"
logwrite "$tod_log return path : $return_path"
logwrite "--------------------------------------------------------------------------------------------"
seen
endif
But when I replace [...] with [*] nothing will be logged to the given file. Only with [...] it works.
What regular epression should be used to make it work with suffixes like .x and .xx and .xxx ?
