Hi, the automatically process of Let's Encrypt certificate renewal includes a Apache reload. But the certificate is used in more services. In virtual servers with dedicated IP, the URL for manage mailing list is using the virtual server domain certificate through Webmin on port 10000, example:
So a Webmin reload is needed to start using the new certificate. The same certificate is used also in Dovecot and Postfix, I think both also needs a reload (I didn't tested it).
Could you add this feature to Virtualmin?
thanks in advanced
