On: If it will matter after today, don't talk about it in a chat room

Exchange rules configured through Outlook are omnipresent.

Sieve might be supported by many email clients, but is pretty much nonexistent in corporate email.

Actually, if someone points me to one hosted email provider that does support it, I'd be glad - I was wondering about trying it out but nobody supports it.

I recently switched some of my email addresses to Migadu. I haven't tested it yet but they apparently offer Sieve support.
