Hi all,
I wonder if someone could point me in a correct direction for debugging mails between Proton and Outlook landing in spam... What happens is
* my domain XXX plugged to mail.protonmail.ch. * my 2nd domain YYY plugged to mail.protection.outlook.com. * every mail sent from Proton to Outlook lands in spam * headers as seen by Outlook indicate SCL score 5
The content I use for the test is not anything synthetic but a real message. In the headers I can also see that the "basic configuration" is correct, i.e.
* SPF passed * DKIM passed * DMARC passed
so this gives no useful information sadly. Maybe someone here has experience with debugging Microsoft? The issue is that this makes my private mailbox unusable as whoever out there uses Outlook as their mail service is not getting my emails. Quite sick...
Thanks a lot for any help, Mateusz
Have you tired talking to support@proton.me? They are usually quite responsive. If that doesn't work DM me.
Best Serge

And I realized it's silly to hide domains, so here it goes
* sender domain - kowalski.xyz * recipient domain where the problem was first observed - amag.ch * my 2nd domain which reproduces the problem - microsoft365.kowalski.xyz
Cheers!

Hi Mat
Probably top-level .xyz is a bad choice. At least in the past, those domains was source of only spam, so we decided at some point to block all of .xyz domains (sure not best practice, but since we only filter for ourself and know our customers, we never had any customer using .xyz domain).
So, probably Microsoft give .xyz pre-score which is bad and if something else is bad, then your mail will end up in spam filter as well.
Just an idea.
Kind Regards
