Anti Spam Policy:
- Mail delivered to our servers should comply to RFC's. Most commonly rfc5321 and rfc5322.
- Reverse lookup records should point back to the sender IP.
- HELO/EHLO of incoming connections should match the hostname of the sending server.
- Senderdomains should have valid A- or MX-records.
- Use InboxSys to to see if your mail complies to the above and more.
- Use the DNSBL checker to check if your domain is blacklisted.
- Use the domainchecker to check your domains for senderdomain authentication.
Sender Domain Authentication:
- Mail from our system has valid SPF records and it's DKIM signed.
- Our current common DKIM selector is "deliv202301".
- Mail from our servers comes only with strict SPF identifier- and DKIM alignment.
- Domains sending from our system are expected to have a DMARC policy set to "reject".
- Use the domainchecker to check senderdomain authentication.
