i've finally got my roundcube working, sending and receiving mails from the internet, prior to installing roundcube, postfix has tls and sasl authentication and was integrated with dspam and clamav using amavisd-new, however when roundcube was installed as the webmail client, i can no longer see from the maillogs the mails being scanned before being sent and before accepting for delivery. is this normal? or roundcube totally bypass them?

TIA
