Hi Bro

I don't know much about TLS but I do know the commands shown below will work. I've done this too many times to know for sure, it will work like a charm. Just ensure your EMail Server supports Mail Relay.

logging enable
logging timestamp
logging list TEST level alerts
logging mail TEST
logging from-address FW01@cisco.com
logging recipient-address johnniewalker@cisco.com level alerts
logging device-id hostname

smtp-server 192.168.10.1

Hi Bro

Have you tried my sugegestion? If it doesn't work, then I believe Cisco ASA FW can't do this at all but if it does, well and good. Give it a try. This is because I have done this with many EMail Servers in the market, and I have not encountered any issues. Give it a try, and let me know if it works or don't

logging enable
logging timestamp
logging list TEST level 7
logging mail TEST
logging from-address FW01@cisco.com
logging recipient-address johnniewalker@cisco.com level 7

logging device-id hostname

How do you know the smtp server wants authentication? Are you seeing any error logs that states this?

Yes, I know your client email accont needs authentication but not for the FW. As long as the FW supported email relay, this is good enough. Have you tried the commands that I've proposed to you. I can't be wrong as I have done this too many times for many large corporations.

Your config is good, my guess is the smtp-server that you're pointing to doesn't support SMTP Relay. Could you try few more other public smtp servers, if any luck 🙂

can you give to me any public smtp server?
