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)
is hard as it is expensive by teaching, running, and maintaining them. Also,
this high load of unwanted emails wastes a lot of costly resources that must be
paid and run by specialists.
Certificates today are like DNS - they must work, because most of the systems
expect them to be there and they must be valid. Especially Google changed for
many services to contact with SSL/TLS enabled by default.
Renewing outdated certificates
Sometimes problems arise and you need to check whether certbot (of Let’s
Encrypt) or cron is still working. Maybe you simply want to check, whether your
certificates are all renewed, you can simply run:
A name, domain, logo, and a draft website - this is the way
MailMum was born out of an internal project.
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.
They will try and will find ways to reach your inbox.
