Hi guys,
I'm having some issues with the email anti spam features.
I've already added 100s of domains to my blocklist, but some emails stil come trough and I don't know where to look or what I'm doing wrong.
1. Plesk native "Tools & Settings > Mail Server Settings > Black List" handles the server-wide domian blacklist settings. I've added 100s of domains there to block some incoming spam.
- domain.com
- another.com ...
2. Plesk SpamAssassin Extension "Tools & Settings > Spam Filter > Black List" handles email adresses and respective domains. Also added every domain there just in a different format:
- *@domain.com
- *@*.another.com
- *@*different.com
- *@*.xyz
But there are one or two domains that never get blocked. Why is that? Is there some setting that I'm missing or how are these feratures supposed to work?
The email header is:
smtp.from=eu-west-1.amazonses.com
header.from=spamdomain.com
Any hints or tips for me why it's not working properly?
Should I turn on the protection based on DNS blackhole lists as well?
Mail server settings:
- "Enable DMARC for incoming mail" is on
- "Enable SPF spam protection to check incoming mail" is on
- "SPF checking continues when there are DNS lookup problems" is on
- SPF checking mode: "Reject mail when SPF resolves to fail (deny)"
Thanks in advance!
