There has been an exponential increase in spam on the Internet
in the recent past and many domains have had to put measures
into place to keep the excessive spam from flooding users'
email boxes.
If you've been sent an error message telling you to visit this
page it's because the domain you're trying to reach is using the
services of spamblocked.net to help prevent spam from reaching
users' email boxes.
Because checking for spam is not an exact science we may have
accidentally blocked your email even though you're not sending
spam.
How it works
Rocket City Hosting uses several local and third-party "blocklists"
to keep spam from reaching user's mailboxes. Depending on the blocklist
that blocked your email there are several steps you may wish to take
to see why your email was blocked:
|
| |
LBL or BSHL
If your message mentioned "LBL" or "BSHL" then
your mailserver was blocked by conscious action of the server
administrator. You should contact our "whitelist" address
above to find out why you were blocked and what you can do to be
unblocked.
ORDB
If your message mentioned "ORDB" you should read the
FAQ at
http://www.ordb.org/faq/ and check your sending IP
address at
http://www.ordb.org/lookup/ to see why your email may have
been blocked.
(It may not be YOUR IP that is blocked, but the IP that your ISP uses to
send mail.) ORDB is the Open Relay Database. This protects our mailserver
from receiving email from servers that are running insecure open relays
that are commonly abused by spammers.
Spamhaus
If your message mentioned "spamhaus" you should read the
FAQ at
http://www.spamhaus.org/sbl/sbl-faqs.lasso and check the site
at
http://www.spamhaus.org/ to see why your email may have
been blocked.
SpamCop
If your message mentioned "spamcop" you should read the
SpamCop site at
http://www.spamcop.net/ and check your IP at
http://spamcop.net/reported.shtml to see why your email may
have been blocked.
SORBS
If your message mentioned "sorbs" you should read the
SORBS site and check your IP at the SORBS website at
http://www.dnsbl.sorbs.net to see why your email may have been blocked.

(It may not be your IP that is blocked, but the IP that your ISP
uses to send email, or the IP may be an open relay.)
Other blocks are put in place due to the number of open relays
on DSL
networks. If your domain name resolves to a DSL or ADSL
domain or is a known dynamic block of IP addresses
used by ISPs
that should not be hosting a mail server (for
example, dsl-verizon.net or *.da.uu.net) you should probably
send email through your ISP's SMTP server instead of directly
from your own home mail server. Or, contact your ISP about
setting up proper reverse DNS so that your IP does not resolve
to a DSL or dialup domain name.
NJABL
If your message mentioned "njabl" you should read the
NJABL "end-user" information at
http://www.njabl.org/enduser.html and the listings page at
http://njabl.org/listing.html for information about how your IP
address ended up in that blocklist.
CBL
If your message mentioned "cbl" you should check the
CBL (Composite Blocking List) website information at
http://cbl.abuseat.org/ and look up your IP at
http://cbl.abuseat.org/lookup.cgi to see why your IP may
have ended up in that blocklist.
Junk EMail Filter dot com
If your message mentioned "junkemailfileter.com" you should check the
Junk EMail Filter dot com website
http://www.junkemailfilter.com for more information. We would like
to thank Junk Email Filter dot com for allowing RCH to use their service as
a part of our spam filtering system.

Subject: RE: Your Subject

The first sample above indicates your email was blocked by NJABL, and the second
that your email was blocked by decision of the local email administrator. Either
way you can send an email to our whitelist address above to be unlisted, and in
the case of the email blocked by NJABL, you could visit their website (see above)
to determine why your email may have been blocked.
