MailMum offers individual services for email administrators to monitor incoming
mail traffic and to control it by blocking IP addresses or even IP networks of
abusive systems using Real-time Blackhole List (RBL) technology. The admin has
full control over the listings by defining parameters, blacklisted (abusive),
and whitelisted (trusted) IP addresses. The defined rules may apply for the
whole account down to an individual server.
Mail System Today
Provided by several sources email traffic is up to 90% or unwanted emails
(called spam or junk). Controlling them through spam filters (like
SpamAssassin or Rspamd)

From a necessity to this service
MailMum was born out of a need to face problems with unwanted emails called spam
or junk. As filters like Spamassassin were
good, but spammers are human, their job is to figure out how to bypass them.
