Here is the issue that most ESPs are facing.. Every 5-6 months something is being enabled or not from Outlook's side which affects either IPs or the domain name of the sender and messages land in Junk folder or in quarantine zone. Now, I do know that the IPs might be affected by complaints or spamtraps, or maybe the client sent something suspicious, but trust me most ESPs don't allow those messages to be sent. Also, when the IPs appear GREEN in SNDS, and SPF/ DKIM and DMARC are a part of DNS authentication and headers appear like this: CAT:HSPM;SFS:(13230031)(4636009)(451199024)(7596003)(356005)(7636003)(86362001)(450100002)(8676002)(1096003)(14286002)(34206002)(5660300002)(336012)(26005)(42186006)(9686003)(33656002)(83380400001)(7846003)(33964004)(564344004);DIR:INB; X-Microsoft-Antispam: BCL:0; X-Microsoft-Antispam-Message-Info: You are expecting that quarantine zone is the last place to find a legit message. For obvious reasons I won't share more details, but I bet that from time to time someone is messing with spam filters that can easily result in false positive and angry senders. In any case, especially when we raised tickets to Outlook, at least please inform your team not to reply like robots. If they will share with us the exact reason why a message landed in junk folder that would really help us. If it is the content, we will change it. If it is related with the sender, we will block the sender. If those are complaints, we will block senders and check their subscription sources, but at least we need something especially when SNDS shows Green IP, 0 spamtraps, 0 complaints. Thank you for reading this.
