Effective June 7, 2013

The Bitworks is committed to maintaining your confidence and trust in us, our products, and our website. To that end, we are providing this notice, which explains our practices regarding the security, filtering and acceptance of e-mail messages through servers owned and operated by The Bitworks Inc.Technology Services.

Acceptance of this E-mail Policy

By sending e-mail through our servers you agree to the terms and conditions of this policy. Without limitation of the foregoing, you understand and agree that (a) e-mail messages sent through The Bitworks servers may be stored indefinitely, (b) The Bitworks may store, access and use the information in any jurisdiction, including jurisdictions in which the privacy laws may be different and less protective than those in your home jurisdiction, and (c) The Bitworks may collect, process and use this information internally for a variety of purposes. Please do not send e-mail messages through our servers if you do not agree to the terms and conditions of this policy. The Bitworks reserves the right to change this E-mail Policy at any time. If we do so, we will post any changes on our Web site.

What is necessary to send e-mail through The BitWorks servers?

In general, following best practices for configuring secure, reliable and RFC compliant e-mail servers will insure the acceptance of e-mail by our servers and subsequent delivery to our hosted domains. The following is a brief, but not necessarily complete list of requirements that will insure the delivery of e-mail through our servers:

  1. Insure that your domain, server or IP address is not listed in any spam e-mail databases.
    • We do not accept e-mail from spam database listed domains
    • We do not accept e-mail from servers connected via a dial-up connection
    • We do not accept e-mail from certain areas of the world known to be origins of spam (we will pre-authorize a valid sender however, please contact us)
  2. Insure that your e-mail server is operating in an RFC compliant mode.
  3. Insure that your e-mail server has a resolvable reverse DNS entry.
  4. Verify your information, insuring you are sending to a valid e-mail address hosted by our servers.

We recommend using the dnstools at to test your domain.

Specific Policies

Gray Listed= Our mailservers will “temporarily reject” any email from a sender / mailserver it does not recognize. If the mail is legitimate, the originating server should try again and the email will be accepted. If the mail is from a spammer it will probably not be retried since a spammer goes through thousands of email addresses and can not afford the time delay to retry. Many non RFC compliant mailer programs will be gray listed by our servers and mail will have difficulty getting through, please resend your e-mail using a standards based mail program.

Empty RDNS= Your mailserver’s IP address does not have a reverse domain name setup. Many spammers will try to send from non-existent or temporary domain names, so we block them.  If you have a valid mailserver and are having problems notify your webmaster and let them know that its not worth doing something unless its done right and they need to put in a reverse dns entry for your mailserver.

Block Lists= We use a variety of block lists that are publicly available on the internet. If your mailserver appears in the list it will be blocked. No, we will not take down the list because your server appears on it – contact us and we will whitelist your server if need be, but there is a charge for doing so. If you are having difficulty getting off a list contact us and we can recommend a number of reputable hosting companies who follow best practices for hosting websites and you will not have e-mail issues.
