Technology Companies Create RAIN to Promote EPC UHF RFID Adoption

Four technology companies have teamed up to form RAIN RFID, an organization whose mission is to promote the adoption of EPC ultrahigh-frequency (UHF) RFID. The organization—founded by Impinj, Intel, Google and Smartrac, and hosted by automatic-identification trade association AIM—is focused on driving UHF RFID deployment through education, testing and support of technology developers and end users. The group announced its launch today at RFID Journal LIVE! 2014, taking place this week in Orlando, Fla.

The word RAIN—an acronym derived from RAdio frequency IdentificatioN—is intended as a nod to the link between UHF RFID and the cloud, where RFID-based data can be stored, managed and shared via the Internet. With a six-member board consisting of an AIM liaison, four elected directors and a president, the alliance was conceived following standards organization GS1‘s ratification of the UHF Gen2v2 standard in November 2013 (see GS1 Ratifies EPC Gen2v2, Adds Security Features, More Memory). That ratification, says Chris Diorio, RAIN’s chairman of the board and Impinj’s chief strategy and technology officer, signifies further maturity in the UHF market, at the same time that item-level UHF RFID tagging for the retail sector has grown exponentially.

Enable antispam functionality on Mailbox servers

Applies to: Exchange Server 2016

Topic Last Modified: 2016-03-28

Use the Install-AntispamAgents.ps1 PowerShell script to install and enable the built-in Exchange antispam agents on a Mailbox server.

The following antispam agents are available in the Transport service on Exchange 2016 Mailbox servers, but they aren’t installed by default:

  • Content Filter agent
  • Sender Filter agent
  • Sender ID agent
  • Protocol Analysis agent for sender reputation

You can install these antispam agents on a Mailbox server by using an Exchange Management Shell script, which is important if these agents are your only defense to help prevent spam. Typically, you don’t need to install the antispam agents on a Mailbox server when your organization uses other types of antispam filtering on incoming mail.

Although the Recipient Filter agent is available on Mailbox servers, you shouldn’t configure it. When recipient filtering on a Mailbox server detects one invalid or blocked recipient in a message that contains other valid recipients, the message is rejected. The Recipient Filter agent is enabled when you install the antispam agents on a Mailbox server, but it isn’t configured to block any recipients. For more information, see Recipient filtering procedures on Edge Transport servers.
  • Estimated time to complete this task: 15 minutes
  • You can only use PowerShell to perform this procedure. To learn how to open the Exchange Management Shell in your on-premises Exchange organization, see Open the Exchange Management Shell.
  • The Connection Filtering agent and the Attachment Filtering agent aren’t available on Mailbox servers. They’re only available on Edge Transport servers, and they’re installed and enabled there by default. However, the Malware agent is installed and enabled by default on Mailbox servers. For more information, see Anti-malware protection.
  • If you have other Exchange antispam agents operating on the messages before they reach the Mailbox server (for example, an Edge Transport server in the perimeter network), the antispam agents on the Mailbox server recognize the antispam X-header values that already exist in messages, and those messages pass through without being scanned again.
  • You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the “Transport configuration” entry in the Mail flow permissions topic.
  • For information about keyboard shortcuts that may apply to the procedures in this topic, see Keyboard shortcuts in the Exchange admin center.

PowerShell: Get-ADUser to retrieve password last set and expiry information

Get-ADUser -identity username -properties *
 get-aduser -filter * -properties passwordlastset, passwordneverexpires |ft Name, passwordlastset, Passwordneverexpires
get-aduser -filter * -properties passwordlastset, passwordneverexpires | sort name | ft Name, passwordlastset, Passwordneverexpires

Export the list to CSV so we can work on it in Excel. In this example we substitute, format table (ft) for select-object.


Get-ADUser -filter * -properties passwordlastset, passwordneverexpires | sort-object name | select-object Name, passwordlastset, passwordneverexpires | Export-csv -path c:\temp\user-password-info-20131119.csv
