Disable Outlook or Thunderbird security warning

[laurent69]

Hello,

How can I do to send email without the security warning?

I want the clients sending mails no longer have a security warning.

I tried with SSL port 465
I tried with port 587 TLS> Mail settings for the entire server> Enable Send Message

Hello,

I solved my problem.
I had a SSL certificate that was activated knew my server. I followed the recommendation Plesk putting in Outlook:
Incoming mail server: domaine.com
Outgoing mail server: domaine.com

The solution is:
Incoming mail server: server.com
Outgoing mail server: server.com
