SMTP::From Address Spoofing


Sender Policy Framework
The Problem: Sender Address Forgery
Today, nearly all abusive e-mail messages carry fake sender addresses. The victims whose addresses are being abused often suffer from the consequences, because their reputation gets diminished and they have to disclaim liability for the abuse, or waste their time sorting out misdirected bounce messages.

The Solution: SPF
The Sender Policy Framework (SPF) is an open standard specifying a technical method to prevent sender address forgery. More precisely, the current version of SPF — called SPFv1 or SPF Classic — protects the envelope sender address, which is used for the delivery of messages. See the box on the right for a quick explanation of the different types of sender addresses in e-mails.

E-Mail::Common Sense


Simple rules:

1) Never put anything in an email that you wouldn't want posted on the lunch room bulletin board.
2) Treat email like a written memo; it's a business record.
3) Never use offensive or vulgar language in an email.
4) Beware what you write; your email can be forwarded to others (accidentally or otherwise).
5) Be careful that the tone of the words is what you want. Consider being over-polite to avoid misinterpretation. (and "let the ink dry" before sending if you are angry when you composed it.)
6) Business is not the place to forward jokes; others may be offended or tired of the interruptions.

Top Ten E-Messes

You inadvertently send porn to your boss:
You receive a picture that you just know your friend Daniel will appreciate. While no one is around, you quickly forward it to him using the function to recognise the name. Daniel doesn't reply, and when you quiz him about it later that evening, you realise he didn't receive it.
Frantically checking your sent items the following day, you realise that the explicit image was sent to Dani, your boss.

You did not secure the salary information document:
HR sends to you the salary breakdowns for 2002, and while reviewing them you realise changes need to be made. You re-save the document, and send it back to HR. Unfortunately, you have saved the document in the company network file name: Salaries.

You swear about your client in an email to a colleague at work:
Your client has been irritating you with their unrealistic demands and constant complaining. You vent your frustration in an email to your colleague, where 'no holds are barred' about your views. But in anger and because you have your client on your mind you send it to him instead. You lose the account the following week.

You forward a joke:
You receive a joke from your old friend, who can always be relied on to provide the best jokes they always go down well. You don't have time to read it through, but send it onto your colleagues so they don't miss out. The racist comment at the end of the email is not appreciated, and sent immediately to HR with a complaint.

Ruining your company's reputation:
You send a MPEG that only a few select friends would appreciate you're very careful about that. Your friends forward it onto a select group, too, and the chain goes on and on. In the end, over 300 people have received an email with your company name, address and URL with a shocking attachment. Not the sort of campaign your marketing department had in mind.

You Had Me At EHLO... : Free Busy generation process: "Free Busy generation process
From working with customers there seems to be some confusion around how Free Busy information is generated and read by the client. There is even further confusion about how to balance Free Busy access across multiple sites. In this post I hope to clear most of that up and provide some guidance that will help you prevent issues with Free Busy."

You Had Me At EHLO... : The free/busy data story: "The free/busy data story
Exchange Free Busy (FB) data itself is not simple or easy to read. This will describe what the data looks like in the Exchange store, how it’s calculated and processed through the Outlook client.

Microsoft Exchange: Publish different free/busy time periods: "Microsoft Exchange: Publish different free/busy time periods"
By default, Outlook will publish two months of free/busy information. While you're able to change this interval in Outlook (by going to (Tools > Options > Calendar Options > Free/Busy Options), Outlook Web Access is also subject to this two-month default, which can prove to be quite inconvenient since OWA users don't have an easy way to change this setting. To make matters worse, even if you do configure Outlook with a longer interval, Outlook may eventually revert back to the two month default. While you can run Outlook with the /cleanfreebusy switch to correct the problem, it still may not "stick."

The solution: On your Exchange servers, add a registry key that redefines the two month default value into something more suitable for your organization.

-Open the registry editor.
-Browse to the key HKLM\Software\Microsoft\ExCDO\Parameters.
-Under this key, add a DWORD entry named "FBPublishMonth".
-The value of this new entry is a number, which is the number of months for which you would like to publish free/busy information across the board, for all users.
-Restart IIS and the System Attendant services on your Exchange servers.
