Sorry for the typo. I meant the actual pen file pointed at in the path. (The one I currently set to t the LE fullchain in hopes it would work).
I think I understand now that roundcube wants the root certs (though I thought fullchain specifically included everything needed from root to local cert, thus the name).
It was previously set to, IIRC, /etc/ssl/certs/something... but that wasn’t working either. I’ll double check that path and see what it looks like it should be and go from there. Maybe even figure out why it stopped working?
'cafile' => '/etc/pki/tls/certs/combined.pem',
Im on an iPhone and out of the country, so ssh in is a special kind of phun! 😉
Thanks a lot for your replies, they are certainly helpful.
