Good to all and thanks for the answers.
I have a sophos utm 9 actualized.
It is in transparent mode as relay for an exchange of the internal network.
I would like to know how to view the smtp authentication log from outside the network.
If I look at the logs in Exchange, the source ip as normal is sophos.
How can you see in sophos this smtp authentication log?
Does Sophos have any brute-force protection for SMTP?
Thank you !!!
