Topic: How to prevent address from being blocked as SPAM
==== Provide required information to help troubleshoot and get quick answer ====
- Linux/BSD distribution name and version: Debian 6
- iRedMail version and backend (LDAP/MySQL): iRedAdmin-Pro v1.6.3 (LDAP)
====
I cannot find a topic in the forum or any documentation how to prevent that a specific address or domain is blocked by the spam filter.
We do receive some customer´s mails that are our of the sudden blocked as spam. Whitelisting the whole domain incl. subdomains and the address itself doesn´t help.
Thanks in advance!
