I'm beginning to get frustrated with my self-hosted mail. Somewhere between my android mail app (Samsung Mail), my desktop app (em client), and mail server (hmailserver), in a rare blue moon I'll have an email that gets out of sync and won't load on desktop. My theory is the android mail app is causing IMAP flags to not get set correctly, since #thunderbird has issues too.

I need a good all-in-one #mail solution that is #FOSS with a good admin UI.
