krystian_rzepa Hi, when I deploy an SSL certificate to MailServer and then try to connect using Outlook, I get a message about an invalid SSL certificate. It is a Wildcard type certificate.
aapanel_sniper Good afternoon, Sir. You can try using a single-domain Let's Encrypt certificate, which will need to replace your previous certificate if it takes effect after successful deployment.
krystian_rzepa aapanel_sniper Thanks for the answer, but using LetsEncrypt is a bit inconvenient as I have to manually change the certificate in MailServer every 3 months. That's why I bought a certificate for all domains.
