If you’ve ever run into this situation, it probably happened just one year after installing Kerio Connect. At the same time your users probably complained about SSL certificate warnings in their mail programs. This is because the default setting for new, self-signed certificates is set to expire after one year. To avoid this situation, consider creating a new certificate using the option of a 10-year expiration. After everyone has connected over SSL and has installed the certificate, you’ll have a full decade to worry about more important issues.
Has your self-signed certificate ever expired?
