The SecureCircle MIME filter (sc-java-agent) is responsible for transparently replacing SecureCircle encrypted file attachments in MIME formatted messages with their decrypted version.
SMTP traffic will be internally re-routed through the MIME filter utilizing the system's firewall (iptables). By default, traffic going to port 12355 on the system's loopback adapter (127.0.0.1) will be redirected to the MIME filter on port 22355. The MIME filter will process the message, then send it to the upstream process listening on port 12355.
iptables setup is done in the file /apps/securecircle/bin/sc-java-agent.sh.
