Greetings.
I need to remove\ban attachment archive from messages like jar -> zip, because normal interlocutors don't send archives like this (in my company), but virus senders loves it .
I'm digged amavis config files and found section for this, there are more file types an extensions, so i uncommented them all:
/etc/amavis/conf.d/50-user:
...
$banned_namepath_re = new_RE(
#[qr'T=(rar|arc|arj|zoo|gz|bz2)(,|\t)'xmi => 'DISCARD'], # Compressed file types
[qr'T=x-(msdownload|msdos-program|msmetafile)(,|\t)'xmi => 'DISCARD'],
[qr'T=(hta)(,|\t)'xmi => 'DISCARD'],
# Dangerous mime types

);
...And messages with unwanted attachments start to get header
X-Amavis-Alert: BANNED, message contains .asc,vmail (1).sql.jarbut still messages pass throught to user mbox with attachment
After that i set
$final_banned_destiny = D_BOUNCE;
and
$defang_banned 1
but it makes no effect.
Is there some method to remove bad attachment with user notify, or wrap whole message to another message with alert?
