does not tolerate UBE (Unauthorized Bulk Email) and will not allow
our servers or services to be used for such purposes.
If you are here because you get the following error message in your
returned email, that means your email had been rejected by our mailservers
because either the mailserver or the connection through which you have sent
your email was listed on a public blacklist.
Please note that when your email was bounced back to you, you should also
get a reason why it had been rejected. For example,
In the above example, the warning code
indicates on which public blacklist your connection is listed so that you
can forward it to your ISP's postmaster to follow up the case. The blacklisted IP
address is also given in the above, in this case, it is
is just an example). Explanation for the warning codes are listed as follows.
Special code -- DYNAMIC IP and ADMINISTRATIVE BLOCK
In addition to the above public blacklist warning codes, there are also
two types of warning codes called the dynamic IP and the administrative block
which refers to the dynamic IP address range or IP addresses previously
known to be used by hackers to attempt to gain unauthorized access
to our systems or virus attack agents trying to spread email viruses.
If you happen to get this code,
please inform us immediately.
More about open relays
Open relays are mailservers that have been proved to be somehow mis-used
or hi-jacked by hackers to send massive amounts of mail which is otherwise
unrelated to the owner of this mailserver. Most such abusive sessions are
initiated by junk emailers, the spammers, attempting to covertly distribute
their unwanted messages all over the Internet.
Blocking open relay or spam-friendly mailservers
Not only we block emails from spam sources, most of the major ISPs around
the world do so as well. If you are doing business with companies in United States,
Europe or UK, you are highly suggested to NOT use an open relay mailserver or a connection
listed in these blacklists because in most cases your emails will either never
be sent or will be quietly discarded by the recipients mailservers.
