The debian supplied version is used:
ii p7zip 16.02+dfsg-3+deb9u1 amd64 7zr file archiver with high compression ratio
ii p7zip-full 16.02+dfsg-3+deb9u1 amd64 7z and 7za file archivers with high compression ratio
I just checked the versions, Debian buster still has the same version, only with a few fixes in the build.
i have :
MailScanner.conf:Un7zip Command = /usr/bin/7z
Usage: 7z <command> [<switches>...] <archive_name> [<file_names>...]
So thats ok.
I have an exeption list for these files also : rules/mailwatch.encrypted.rules
But the sender domain/ip is not in my white list.
