Yesterday i followed Xsiege's how-to to set up my sendmail server.
The only part i did not use was the part about enabling people outside of my local network to relay through my server as i don't need anyone else to be able to use it.
The set up is fine and i can send and receive with no problems.
The question i have is with a potential issue i've found in my log files:
sm-mta: STARTTLS=client, relay=mail.myisp.com., version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-SHA, bits=256/256
Although the 'PLAIN' authentication is working and the mail is accepted for delivery, this has worried me slightly. I would prefer to have the connection encrypted with tls/ssl if possible, but i'm not sure how i implement this into my config.
I have looked for other sites, but all the info i've found seems to relate to people not being able to send outside of their network at all, which is not the same problem i'm having.
Does anyone know how i can get this fixed, or at least confirm if it's something i need to worry about?
