Question: I have been using AWS SES for a year now for my SaaS. I added DKIM, SPF and DMARC. Yet some people are still not receiving emails. I provide instructions for them to add my domain to their safe senders list. That seems to resolve it. I would like to avoid end-users having to do that.

I am wondering if using a dedicated IP would help to improve delivery. Anyone has experience with that?

Answer: 
Yes, technically you can modify files in the underling volume, but Gluster will **not** be notified about your changes, and therefore they may not be replicated to other Gluster nodes.

This is **very much not recommended**, and could mean that your servers end up with different underlying files, which can lead to unpredictable behaviour/data loss.
Once I have several files copied directly to the brick, is there any way to make Gluster be aware about those new files?
