In my experience (self hosting mail since 2005) signing up for SNDS does factor in. Although last time I had trouble with delivery to MS, my hosting provider Linode’s support also helped out by contacting MS back channels on my behalf. The biggest problem I (rarely) have is when whole IP blocks end up on a ban list that MS seems to really trust. That said, fuck it, I will keep fighting the fight and self host my mail like a stubborn old git :p

Chobbes@lemmy.world 1 year agoI’ve never heard of anybody relaying just the Microsoft e-mails, but that’s a really funny spiteful solution.
Lately I’ve been able to send to outlook just fine (maybe it’s just dumb luck, who knows). I think I had troubles initially because they’re really picky about rDNS matching the MX exactly. I also signed up for SNDS just in case, but I don’t know if they factor that in…

Hell yeah :). I’ve heard people have had problems with Linode’s IP blocks with MS… I’m glad to hear that Linode was actually able to help you resolve the problem. The biggest problem seems to be that you just might not realize if your e-mails are being dropped. Not sure if MS will notify you via DMARC if your IP block has been blacklisted, from the sounds of things they probably don’t and just silently drop things, so I guess you have to monitor the blacklists yourself?

Ooh, lucky you! Maybe it was both the rDNS and the SNDS. Part of the problem IMO is it’s such a black box…

Definitely. It’d be nice if there was more reporting when a provider drops your messages.
