Wyith Limited d/b/a 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 DSBL WARNING 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 111.222.333.444 (caution: this is just an example). Explanation for the warning codes are listed as follows.


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.
