    Hi there,

    for some reason, only Yahoo cannot connect to my server to deliver mail, due to TLS error. All other domains are ok. I believe this is an error in there, or not? So, my users cannot receive messages from yahoo.com and I dont know what to say to them :( Any ideas why this error or any way to fix?

    My certificate is auto-generated by cPanel.

    Outgoing messages are ok.

    Hello :)

    Do you have any firewall rules enabled on this system? If so, check to make sure the Yahoo IP addresses are not blocked.

    Thank you.

    I have some IPs blocked using Fail2Ban-like system, but Yahoo' IPs can connect to the server, but fail to negotiate the TLS connection... I dont believe this is related, means, Yahoo cannot send a message using TLS because another IP is blocked. Right?

    I suggest you take that as a hint... install a real certificate.

    Thank you quietFinn, I'll buy a real certificate to see if it fixs the problem.
