Question Update Let's Encrypt not working with mailserver SSL

ahbirkner

New Pleskian
Hi,
if i update SSL manuallly in plesk everything works fine. using: Tools -> SSL/TLS -> Secure Plesk and Mailserver
When I check Plesk new certificate the new time period (new SSL-Certificate) will show up in the browser
But if I try to connect via Outlook, I get an error, saying the certificate time is up...

So I used: //email/testTo:
an got:
STARTTLS command works on this server
[000.801]Connection converted to SSL
SSLVersion in use: TLSv1_2
Cipher in use: ECDHE-RSA-AES128-GCM-SHA256
Perfect Forward Secrecy: yes
Certificate #1 of 4 (sent by MX): EXPIRED
Cert VALIDATION ERROR(S): certificate has expired
So email is encrypted but the recipient domain is not verified
Cert Hostname VERIFIED (...)
Not Valid Before: Dec 12 08:28:06 2021 GMT
Not Valid After: Mar 12 08:28:05 2022 GMT

which is the old (SSL-Certificate) one...

I have to admit that I first used the certificate from one domain and did not use "Secure Plesk...", which I use now...

Any ideas how to fix that.

I disabled postfix, dovecot and tried again. Maybe something locked the files... but I could not supply the new certificate...
