It's possibly yet another issue relating to the long streak of problems seen the recent months by primarily self-hosters trying to reach people and businesses behind Outlook servers. The past few weeks a lot of my e-mails to friends and family using Hotmail have gone missing. All envelopes were OKd by Outlook servers, nothing bounced, e-mails just gone. My setup is clean, my network is clean.

I'm fine with providers imposing some default level of spam protection but as a user I'd like the option to disable it, even better if I can disable it per domain or sender. The old technique of adding the sender to your contacts doesn't work reliably anymore.

"First time?"

It's not months it's years.
