Is there a way to do e-mail logging using SSL/TLS on a Cisco ASA? SMTP seems straight forward, however, I can't do SMTP (Port 25 TCP) outbound as my ISP has it blocked.
Thanks in advance!
Depending on your context.
Are you still using ESA as your mail proxy?
With ESA, as far as I know, enabling ESMTP on ASA will cause issue on TLS traffic.
I am not using an ESA, I cannot seem to find any Cisco documentation on how to configure e-mail logging on an ASA using SSL/TLS. Does this documentaion exist? I am not having inspect issues, my pcaps show no 465/587 TCP traffic leaving my outside interface when a logging event occurs. When I configure e-mail logging using SMTP I see port 25 TCP traffic leaving, so I must not be configuring it correctly for SSL/TLS.
I will move your discussion to the ASA/Firewalling section since there will be more people with ASA skills to answer your query there.
Discussions in Email Security are normally around the Cisco ESA.
