[AMaViS-user] local sender notification

[Florian E. <fl...@ar...>]

Hello virus and spam haters out there ;-)

The relevant parts of my amavis.conf follows:

===
$final_virus_destiny      = D_BOUNCE;
$final_banned_destiny     = D_BOUNCE;
$final_spam_destiny       = D_PASS;
$final_bad_header_destiny = D_PASS;
#$warnvirussender = 1; (ie. = 0)
#$warnspamsender = 1; (ie. = 0)
#$warnbannedsender = 1; (ie. = 0)
#$warnbadhsender = 1; (ie. = 0)
$warnvirusrecip = 1;
$warnbannedrecip = 1;
#$warn_offsite = 1; (ie. = 0)

$viruses_that_fake_sender_re = new_RE(
[...]
  [qr/.*/ => 1],
);

With that, I hope to limit the risks of false notifies and DDOS attacks
using notifies. Everything seems to be okay, someone always gets notified
when a message is being dropped. However, there is one case no notification
is sent: when a local user sends a message with a virus attached to a remote
one. Sometimes, virus scanners have false alarms and then messages are
silently dropped that have no viruses. This is something that is not good.

Do you have any idea what could be tweaked on the above configuration to
limit that risk?

Thanks
Florian
