Can ESA be deployed transparently?
We have an ISP customer that wants to block outbound spam emails coming from their subscribers transparently without any header modification or subscriber's knowing their emails are being analyzed.
The use-case in particular is to block outbound spam generated by compromised systems [botnets] by routing all SMTP traffic to ESA deployed transparently to analyze such email traffic and block them. The ISP wants to safeguard their IPs from being blacklisted because of such outbound spams.
Please note ISP doesn't have control over subscriber's mail servers apart from giving them Internet services only.
