Reseller (All)



We have started to receive messages from a number of resellers saying that the SSL certificate for mail has suddenly stopped working. We're working to resolve this across the board, but are currently advising affected clients to enable this manually by logging into Plesk > tools and settings > SSL/TLS Certificates and changing the "Certificate for securing mail" from None to instead use "Let's Encrypt certificate (server pool). If one is not present, go back one page and select the Let's Encrypt button.
