RBL is a list of networks that are misused
by spammers to send unsolicited emails. Anything
listed in the RBL is unceremoniously bounced.
The idea behind RBL is simple: block traffic from
spammer IP addresses and thus prevent the traffic
from reaching a destination on internet. The MAPS
RBL (Realtime Blackhole List) is said to be the
originator of Realtime Blackhole list.
System administrators set rules on the mail server
to use this list for rejecting incoming mail.
The result promises less spam reaching recipients'
inbox. However, legitimate users who unintentionally
share a domain with spammers may have their emails
blocked as well. Customers of ISPs that use RBLs
may never know what they are missing.

How did you land in
a Blacklist?
You have a legitimate business interest and have
no intention of spamming but still you are blocked
from further communication and blacklisted. All
planning, investment is ruined in no time. How
did you land in a Blacklist?
Reasons
You harvested email addresses
of your prospective from a vendor.There is
no guarantee that the vendor list is of opt-in
customers and that too of your customers. Never
put in all your faith in such lists.
You might have swapped list
from your business associate, customer did not
give you permission or for your newsletter.
Even after customer opted-in
for your service, you did not take the pain
of confirming about it with them.
You may be listed maliciously
through one complaint of a client.
You may have been listed
maliciously by your competitor.
Your IP falls in the range
of addresses that are suspected of spamming
and already blacklisted.
If you using the same IP
that the already blacklisted spammer is using,
you may also end up being listed.
If your subject line or sender's
address does not give the impression of being
legitimate.
Your content is all crammed
with nothing substantial to talk about.
You email frequently without
any consideration to, 'will the recipient like
it'.
You by default or intentionally
emailed recipients who opted out of your service.
Sometimes Blacklist organization
presumes that your IP or company is a potential
spam sender. They then add every IP address
in that network to their Blacklists. They do
this regardless of whether spam has been sent
from those ISPs.
Most Blacklist organizations
do not care whether you are legitimate or not, they
only consider how many complaints they have received.
Sometime, only one complaint is enough to fall in
the pit. The following ways may not guarantee you
100 per cent solution but you do not get reported
often.
Ensure your email server
is not an open relay.
Go in for doubt-opt in option.
Do not use any spammer tricks
Promptly handle unsubscribe
requests.
Use correct header data.
Try mixing up your lists
so that they contain addresses from different
providers. Never send to lists with only one
provider, if you are doing so, there are higher
chances of getting blocked.
