After switching to a new server/host for my business' website, and setting up the email on my iPhone, a strange bug has started happening. About half of my new emails automatically show as having been read. Some do, some don't, and I cannot figure out why. I have to manually click the 'star' to show them as not read. I spent an hour on the phone with Apple looking at my phone mail settings and shared the screen for him to look at my Roundcube settings, for what it was worth since he wasn't terribly familiar with it, but he was at a loss.
My notifications are off on my phone so it's not that they're being "read" on the phone. In the Roundcube settings I have tried "Never", "Immediately" and "After 5 seconds" for the "Mark messages as read" just in case that might do something, but it didn't.
I get quite a bit of email for my business and having to comb through them and mark individually is a time consuming nuisance. Any suggestions?
My email comes through my company website. I'm using Roundcube Webmail 1.4.6. KnownHost is my server/hosting company for my website. Not sure what, if any, other information would be useful or necessary to share.
Thank you in advance!
