A crate for deconstructing and constructing Spf (Sender Policy Framework) records.

This is the latest release.

Features:

• warn-dns
• strict-dns (using the addr crate)
  • With this feature enabled a syntactically invalid dns host will return an error.

Hey there

I’ll get straight to the point.

We have SPF applied and according to many online spoofing checkers tools it say that spoofing is not possible for our domain.

HOWEVER, our email keep getting spoofed, many people keep getting emails from our domain, emails that does not exist in our mail server and has never been created.

Keep in mind that we have about 100 email account for our employees, so its easy to keep track of each email and its owner.

So is it possible to bypass SPF and send a spoofed email?

Thanks in advance

Hi guys. I've been researching SPF over the last week and there are a couple of things I have not been able to determine.

1. If I add an SPF record to our DNS, will I be able to see which emails have been blocked?
2. What happens to the email if it is blocked? Will the sender of the email get a non-delivery error message or does the email just disappear?

Thanks for your help.

I have just written this letter to a peer I saw was interested in technology issues - he's the chair of the Lords Information Committee which oversees IT in Parliament. Does anyone have any suggestions on who else to send it to - or comments on the letter itself?

Dear Lord Kirkwood,

The Government are currently doing nothing technologically to prevent email spammers impersonating official Government email addresses, or employees. At the moment, it is possible for anyone to send an email which, for those not technically-inclined, looks like a UK government email address. Interestingly, Parliament does use this!

However, there is a technology called "Sender Policy Framework" (SPF) which works by a simple process. It is a completely free system which utilises existing technologies the Government already uses.

The email protocol (called SMTP) permits any computer to send email claiming to be from any email address. This is exploited by spammers who often use forged email addresses, making it more difficult to trace a message back to its sender, and easy for spammers to hide their identity in order to avoid responsibility. I believe that the ability for anyone to forge sender addresses is a security flaw in modern SMTP.

SPF allows the owner of an Internet domain to specify which computers are authorized to send mail with sender addresses in that domain.

Receivers verifying the SPF records may reject messages from unauthorized sources before receiving the body of the message.

A government employee sending an email would send it from an authorised computer, while a spammer pretending to be a government employee would not have access to an authorised computer. This receivers which utilise this technology, which include Gmail and many other large online email providers, would be able to delete the email knowing with 100% confidence it was fraudulent.

I put in a Freedom of Information request to the Cabinet Office and was surprised they had not even discussed implementing this technology. --> http://www.whatdotheyknow.com/request/sender_policy_framework

More information on SPF is available on Wikipedia: --> http://en.wikipedia.org/wiki/Sender_policy_framework

I would be very happy to work with you further on this, perhaps drafting letters or parliamentary questions.

I believe implementing this technology would be valuable both to the Government, in knowing that any email sent out was verifiable as being from a government employee, and to people ac

I have to give a presentation on SPF records on Friday and would love anyone to just dumb it down for me. I just basically need to dumb it down for my audience but I have worked with it very little. Any analogies or simplified explanations of the process from sending mail server to receiving mail server and what exactly goes down would be great. I'm a junior network admin and just have limited experience with DNS across the web if anyone wants to just tackle that and relate SPF to MX records. I'm especially interested now with all the SOPA stuff going down. Thanks guys.

Hello All,

We're currently in the process of migrating to office 365, and our migration is scheduled for Friday at 5pm. Yesterday, I had some users starting to get delivery failures when sending to some external email addresses. For the most part, everything is working fine. The messages vary slightly, but the one today that 2 users could not send to came back with a rejection of "Rejecting for Sender Policy Framework". I get the same error. I've googled the error, but I can't really find what would have caused this error. We've been in the migration process for weeks, but haven't made any changes for at least a week. Has anybody seen this error before? I'm not sure if its the right place, as I don't think its an exchange specific issue, but I figured i'd start here.

Hi all,

I've been thinking... for those of you who have a no return/no cancellation policy, how do you handle returns ? As in: what do you do if a parcel gets returned to you for whatever reason (i.e. recipient couldn't be reached or refused to accept the parcel, maybe because they didn't want to pay additional fees/customs) ?

Do you cancel the order ? Refund ? Do a partial refund ? No refund at all ?

I'm curious.

Beginning Monday, January 10, 2022, Federal Reserve Bank of New York staff will release a four-part series on its Liberty Street Economics blog about the Federal Reserve’s monetary policy implementation framework. One post in the series will go live each day between January 10 and January 13 at 7:00am EST.

The purpose of this series is to help explain how the Federal Reserve implements monetary policy today. This series is also a follow up to a speech by the New York Fed’s Lorie Logan, Manager of the System Open Market Account, last fall: Monetary Policy Implementation: Adapting to a New Environment. The blog series aims to clarify:

• How the Fed’s approach to keeping its key rate—the effective federal funds rate (EFFR)—within its target range has changed since the 2008 global financial crisis;
• The role of the Fed’s key policy implementation tools—the interest on reserve balances (IORB) and the overnight reverse repurchase (ON RRP) agreement facility—in supporting the current framework;
• How and why “technical adjustments” to the IORB and ON RRP rates are sometimes used to steer the EFFR without changing the Fed’s monetary policy stance; and,
• How the Fed’s new backstop facility announced last year—the domestic standing repurchase agreement (repo) facility—works to support control over the federal funds rate on occasions when money market pressures unexpectedly emerge.

Authors are: Gara Afonso, Lorie Logan, Antoine Martin, William Riordan, and Patricia Zobel.

Press Call on the Monetary Policy Implementation Framework Series:

An educational deep background press call will take place on Thursday, January 13 at 2:30pm EST to provide further context on the series. Journalists interested in participating should RSVP to Betsy Bourassa and Mariah Measey at Betsy.Bourassa@ny.frb.org **a

does anyone have any prioritize the future of humanity framework cards?

I will freely admit I am a bit of a policy and detail-orientated wonk. I spend a lot of time actually reading the meat of bills, studies, and analyses.

A lot of progressive and populist policy making envisions a world they want to operate in not necessarily the world we are actually in.

The day when M4A passes into law, we are going to have to shift the incentives in the healthcare industry to focus on outcomes and less on profits.

We are going to have to dramatically expand healthcare facilities and the healthcare worker supply.

Whenever UBI is passed into law, we are going to need to create more domestic production capacity.

If we ever get to GND with nuclear passed into law, we are going to have to dramatically increase investment in high voltage electricity transmission lines.

We need to start building and changing the systems today for the policies of tomorrow. Otherwise the growing pains may cause people to step back from committing to the policies.

Private industry is a large part of the system. We need to start changing the incentives and practices today to be ready for the policies of tomorrow.

OIP-56: Policy Framework v2

Snapshot has been posted for voting between now and 2 January.

As Olympus has grown, the technical levers used by the policy team have become more complex, and now include Olympus Pro, the v2 bond contract, v3 liquidity pools and potential cross-chain deployments with some liquidity mining incentives. The new bond contract is particularly important to reflect in the updated framework: because the new contract does not allow changes to certain bond terms once a bond is launched, it is important that the policy team be able to launch and deprecate bonds to maintain the level of agility mandated by the community in OIP-22.

V2 of the Policy Framework seeks to reflect these developments.
