Use S3 for email storage?

Hello,

I would like to use a cPanel install only for emails. No HTTP, no FTP, no Ruby etc. Just email.

In order to store email data I would like to use S3 via S3FS*.

So here's the question: should I set the entire /home directory to be stored on S3 (set via WHM -> Home directories to be created) OR only the /mail directory for each user?

Thanks,
Razvan

* Yes, I know that this is not an "officially cPanel supported option" but - considering the implications for other dedicated options like OpenXchange & Zimbra - I cannot find a better solution at this point.

 

I'm fully aware that cPanel doesn't supports NFS mounts, but can you please let me know what could be the possible consequences for such a scenario, especially when for the "mail" folder which doesn't has any symlinks and - in theory - doesn't continuously write logs?

I'm willing to take a risk, but before doing so I want to be aware of the implications.

Thank you!

 

Yeah that would really be a bad thing.

Can you please provide some minimum information about this and why/what could go wrong? I'm ready to dig deeper into this, but in order to do so I need a starting point.
