Hi,
I read many threads now and found no solution to my recent problem, so hopefully someone can help me.
The server config is:
- multiple domains (~30) on a dedicated server with 1 IP
- Let's Encrypt extension is installed
- Plesk version: Onyx 17.8.11 #20
- Let's Encrypt version 2.6.1.398
- all domains (www and webmail) are secured with Let's Encrypt
- Plesk and E-Mail is secured with certificate from Serverpool with Let's Encrypt
- Standard-Site under IP-address is set to "None"
- the SSL report under www.ssllabs.com throws an Overall Rating of "A", all green, for the main domain and the other domains
The problem now is, when fetching mails with Outlook over SSL (port 995/25 TLS) each client gets the error "Target principal name incorrect" - for the main domain of the server and all other domains.
e.g. for
mail.maindomain.de
mail.domain1.de
mail.domain2.de
etc.
The error appears since the the server certificate has expired. It has been renewed for the next 3 Months, when inspecting the certificate in the MTA is says valid until 17th Dec 2018.
Any ideas what to do next?
Thanks for any advice
Please let me know when more info is required
