ActiveSync is to Exchange as IMAP/POP3 is to other email providers.

So if you want your email client to speak with an Exchange server you’re using ActiveSync, not other protocols used by other types of servers.

Exchange ActiveSync is a licensed protocol. If any FOSS app handles it for free I’d love to know.

Soju is to Korea as sake is to Japan. OP mentioned Korea so it’s unlikely a mistake. And Sake is a similar rage for abv. It’s naturally brewed and not distilled. Most yeast dies around 20% abv so virtually no naturally brewed product can get stronger. Vodka and other spirits are distilled so the skys the limit. Most are 40% for historic tax reasons.

Pi Hole successfully blocks all that.

Note I have my router redirecting all requests to port 53 (DNS) to the pi hole for those things that don’t obey the DHCP DNS. Not sure if Roku is one of those offenders, but I haven’t seen a Roku ad in years.
