Zip file Block

[itr]

Hi,

im using

Deny Filenames = \.zip$ in the Mailscanner.conf for blocking all zip files.
But is it possible to block all zip files except the files starting with (for example): ITR_*.zip?

Thank you

That's a tough one.

You don't want to block basically "ITR_*\.zip$", so if you inverse that it with allow everything else (including zips).

So, you will need to use the rulesets instead.

How about this?

/etc/MailScanner/filename.rules.conf (use tabs between not spaces)

Code: Select all

allow	ITR_*\.zip$	Allow zips with ITR Prefix	Allow zips with ITR Prefix
#allow	\.zip$	-	-
deny	\.zip$	Deny zips	Deny zips

[itr]

Hi,

thank you for the answer.

Its now blocking the zip files with the new "Deny zips" message, but when sending it with prefix ITR_Test.zip its also blocked via the "Deny zips" rule.
Is the deny rule "higher" then the allow rule?

Got another idea?

Thank you!

Dang, block overrides allow...

What about this?

Code: Select all

deny	(?!ITR_)\.zip$	Deny zips	Deny zips except for those with ITR prefix

Hi,

mhm comes up with the new error message "Deny zips except for those with ITR prefix" but it is blocking files like "ITR_523.zip"

Thank you

Forgot a wildcard...try this....

Code: Select all

deny   (?!ITR_).*\.zip$   Deny zips   Deny zips except for those with ITR prefix

Hi,

another question

is it possible to notify the sender AND the receiver that a zip was blocked? Also is there an option to just set *.zip to a score that it gets blocked and could be released via the Link that is sent from EFA3?

Thx
