Our Email Policy

Overview


If you are currently BlackListed, then please see this article. You can contact us here. You can check if you are on a blacklist by doing a search here. The individual blacklists that we use are listed below. Please note that if you are blacklisted you will need to remove yourself from the blacklist that has you listed.

Just to re-iterate... We are not the ones blacklisting you (unless you are on our bl.worldguard.com.au list). Instead you are listed in a public blacklist that we happen to use.

If the bounce message you recieve has 'Invalid Content', then your email is being blocked due to an invalid attachment. This could indicate that it is a virus or is suspicious in some way. Please contact us if you feel that the attachment should not be blocked.

Junk emails and Viruses are starting to turn a fairly useful technology into something that is becoming more and more of a pain to administrate. There is almost no-one who has not received at least one virus or one bit of unsolicted email (SPAM).

WorldGuard Technologies takes a zero tolerance approach to spam and viruses and will resort to terminating accounts if any user of our server knowingly sends spam.

We will block any incoming and outgoing viruses that pass through our servers and subscribe to various blacklists (including maintaining our own) to eliminate all incoming unsolicted emails or spam to our clients.

If you have been directed to this page in a bounce email, then either you, your mailserver or even your ISP may be sending viruses or be blacklisted due to sending spam.

If you need to contact us, then please use this form as it will be allowed through any filters. Whilst we really do not like spam, we also do not wish to block anyone who is not at fault. I am always happy to add legitimate servers to my whitelist that is used now by quite a few companies.

BlackLists and WhiteLists


One of the most effective ways of preventing SPAM is to make use of BlackLists and WhiteLists. BlackLists are a list of IP addresses of mailservers of known spammers or sources of SPAM. WhiteLists are a list of IP addresses of known good addresses that are exceptions to any blacklist.

We use the following lists to determine if a message is a piece of spam: -

  • whitelist - qmail.bondedsender.org - Any ISP who is on this bonded sender list is automatically Whitelisted and allowed to send emails. See http://www.bondedsender.org for more information.

  • whitelist - wl.worldguard.com.au - Our own whitelist. As much as we try to block spam, unfortunately some companies have no control over their ISP and may be blocked without actually being at fault. Anyone who fits this criteria and by being whitelisted does not add to the amount of spam we receive is eligible to be whitelisted. Please contact us if you are in this scenario.

  • blacklist - bl.worldguard.com.au - Our own blacklist. If any of our clients receive spam or any of our spam traps receive emails then those addresses will be added to this list. Please note that any addresses added will remain on this list till removed at our discretion. You may request to be removed here.

  • blacklist - korea.blackholes.us - Korea has a blatent disregard for spam and are currently considered internet pests. This mailserver does not accept mail from any Korean IP. See http://www.blackholes.us.

  • blacklist - bl.spamcop.net - Spamcop lists IP addresses which have transmitted reported email to SpamCop users, which in turn is used to block and filter unwanted email. See http://www.spamcop.net.

  • blacklist - list.dsbl.org - The DSBL contains the IP addresses of servers which have relayed special test messages, occurring when a server is an open relay, an open proxy or has another vulnerability that allows anybody to deliver email to anywhere, through that server. See http://dsbl.org.

  • blacklist - relays.ordb.org - ORDB.org is the Open Relay Database. It stores a list of IP Addresses of verified open SMTP relays. See http://ordb.org.

  • blacklist - sbl-xbl.spamhaus.org - Spamhaus tracks the Internets Spammers, Spam Gangs and Spam Services, provides dependable realtime anti-spam protection for Internet networks, and works with Law Enforcement to identify and pursue spammers worldwide. See http://www.spamhaus.org.

  • blacklist - cbl.abuseat.org - The CBL takes its source data from very large spamtraps, and only lists IPs exhibiting characteristics which are specific to open proxies of various sorts (HTTP, socks, AnalogX, wingate etc) which have been abused to send spam, worms/viruses that do their own direct mail transmission, or some types of trojan-horse or "stealth" spamware, without doing open proxy tests of any kind. See http://cbl.abuseat.org/.

  • blacklist - dnsbl.sorbs.net - The Spam and Open Relay Blocking System was conceived as an anti-spam project. See http://www.sorbs.net.

  • blacklist - dnsbl-1.uceprotect.net - UCEPROTECT-Network is a noncommerical Project to stop UCE, also known as Spam on the Net. This list blocks individual IP addresses of spam sources.

  • blacklist - dnsbl-2.uceprotect.net - UCEPROTECT-Network is a noncommerical Project to stop UCE, also known as Spam on the Net. This list blocks C class subnet addresses of spam sources.

Proposal


I've thought long and hard about better solutions to AntiSpam and am proposing to implement the following solution in the near future.

If a message passes all the blacklists, then it will be automatically added to a personal whitelist applicable to the end client. This means that good mailservers will not need to have constant blacklist lookups made on them and will not be so subceptible to being blacklisted when one of the lists that are out of our control decide to blacklist an entire ISP. This means its a whitelist that slowly learns what email a particular client recieves.

Any IP on the whitelist that ever spams is removed from the whitelist permanently and will always go through the blacklist checks, including our own blacklist.
