The default, self-signed certificate which was installed on plesk install has now expired.
Now roundcube webmail is not working. When sending a message the following error appears in the UI:
An error occured.
SMTP Error (-1): Connection to server failed.
The following appears in /var/log/mail.info:
postfix/smtpd[29398]: warning: TLS library problem: error:14094415:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate expired:s3_pkt.c:1300:SSL alert number 45:
I would like to renew or replace the self-signed certificate with another self-signed certificate. I do not want to use letsencrypt or a commercial certificate. How do I renew the self-signed cert?
