Hello group. I attempted searching through the discussion archive but couldn't find anything.
I have a site currently using a 3rd-party email provider. We would like to bring everything inhouse.
Currently, our email hosting provider is supporting approximately 11,000 users.
I would certainly like to see RoundCube used as the front-end but am looking for any guidance regarding the back-end (software and hardware).
Thanks (in advance) for your help.
