Disable SSL certificate for SMTP

[NicolaA]

Hello, is there any way to disable the SSL certificate for SMTP ? I'm currently running Plesk 10.4.4 MU4 on CentOS 6 x64, MTA Postfix.

Thanks in advance

Thanks for your response, but I was looking for disabling at all ssl certificate for SMTP. In fact, I don't want my clients to download and install any certificate using email client such as Outlook. I'm experiencing some troubles with this issue, because mail client ask if you want to use the server certificate on every send/receive input, even if the certificate is locally installed and recognized for trusted organization.

I guess you could just close port 465 in the firewall, so no one will be able to use SMTP over SSL.
