Hi, a user of my server complained, that some of his mails don't reach mail accounts from hotmail/live/outlook etc. that complaint is nothing new, the problem exists for months now.
the users mails are dkim signed, the domain has DKIM and SPF TXT DNS records, since yesterday there is also a DMARC record. i investigated further, set up test accounts on both ends and indeed, they are accepting the mail with 250 but it doesn't appear in the inbox or even junk folder. According to SNDS, the IP has "normal status" and no events are logged. i reached out to them through their form two times and got the same answer twice, that the IP doesn't qualify for mitigation. the thing is, i can't figure out a) why they discard the mails b) why they don't reject them, that would be much better we're a low volume sender, so i investigated the logs manually and can't find any outgoing spam. all of the users recipients do really want to get these mails and are very upset that they don't receive them. and even if they didn't want to, they could tell via mail or even in person, as all of them are at the same university (and are friends). perhaps someone has an additional idea, another form or contact address or what can i try to solve this? ticket numbers: SRX1342522740ID / SRX1342663522ID.
