Crossbox SSL Certificates not renewing

Affected Systems
We are seeing reports trickle in that Crossbox (mail.mxlogin.com) is not properly renewing SSL certificates for custom hostnames. If you are uncertain if this relates to you, only if you did this: https://docs.mxroute.com/docs/branding/crossbox.html Far from everyone does that. So this means nothing to most of our customers. But for those it does mean something for, it means a fair amount. But here's the thing. This is licensed third party software and the developers appear to be going dark. Now if you're picking up what I'm putting down, my hands may be tied here on how we'll react to this soon. My recommendation would be to make other plans. Other plans: - Custom Roundcube URL (MUST be webmail subdomain): https://docs.mxroute.com/docs/branding/customhostnames.html - Our one-size-fits-all Roundcube: https://webmail.mxroute.com - Literally any email client you desire
