ITS Email Protection Strategies

University-wide email protection strategies


ITS has implemented a number of email protection strategies to protect the personal information of students, faculty and staff. See details below:

[External] Email Tagging

Phishing scams remain one of the top cybersecurity threats across the university. They can take the form of email scams by impersonating people we know. The majority of these types of scams start with a message originating from external email systems. As part of Temple's effort to reduce phishing and other email scams, all emails from external senders now include an [External] tag in the subject line.

No additional scanning, filtering or sorting of email is performed. If the message originates from a non-Temple University system then [External] is added to the beginning of the email subject line.

Please note that an [External] tag does not always mean that the message is unsafe or illegitimate. The purpose of the tag is to prompt the user to apply an appropriate level of scrutiny when reviewing the contents of the message in question.

In some cases, after a thorough review from ITS Information Security, messages from specific trusted external email systems may be excluded from the [External] tag. In these cases, you are still advised to proceed with caution.

A sample message showing the [External] tab appears below:

To help with identifying suspicious messages, Temple is using an automated threat analysis system called Proofpoint. You can report suspicious messages to Proofpoint by opening the message and clicking the Report Phish button in your TU Gmail or Outlook/Exchange account. By clicking the Report Phish button, Proofpoint will evaluate the message and then notify you whether there is a threat and what actions will be taken to safegaurd your privacy: 

  • Malicious messages are quarantined and/or forwarded to the ITS Information Security team for further remediation. 
  • Spam messages are removed from your account.

To learn more about Proofpoint and the Report Phish button, see our ITS Phishing page


Outlook 365 enables you to encrypt messages sent to other Temple Outlook 365 email accounts or to accounts outside of Temple. If you are sending a message containing HIPAA Protected Health Information (PHI), Personally Identifiable Information (PII) or other confidential/sensitive information, make sure to encrypt it as shown below.

Important Note: At this time, encryption will not work when sending messages to Temple Gmail accounts. Also, the encryption feature is not currently available to alumni.

Outlook 365 Safe Links

Safe Links is an Advanced Threat Protection feature in Outlook 365 that scans hyperlinks in an email message for known malicious content or for content that Temple Information Technology Services has found to be unsafe. It provides a robust first line of defense against phishing scams, as it enables us to supplement Microsoft’s pre-determined security protocols with Temple's own security threat assessments.

The service works by updating the hyperlinks to flow through Microsoft's Advanced Threat Protection Safe Links service. In most cases, you will not be aware of the service, as the actions are taken in the background. You will, however, be aware of this service in the following cases:

Hyperlink Marked Malicious by Microsoft
When a hyperlink is marked malicious by Microsoft, you will see a message similar to the following:

Hyperlink Marked Malicious by Temple Information Technology Services
When a hyperlink is marked malicious by Temple Information Technology Services, you will see a message similar to the following:

Messages Sent in Plain Text Format
When a message is sent in plain text format, the hyperlinks are replaced with a Microsoft link (https://​nam10.safelinks​.​ followed by a long string of characters:
Example of Safe Links hyperlink in plain text

Consider Adding a Signature to Set Expectations
If you send plain-text emails or have an app that sends plain text emails, consider adding a signature message similar to the following that sets expectations for the recipients:

Temple University e-mail is protected by Advanced Threat Protection Safe Links by Microsoft. Hyperlinks in this e-mail may display with a fairly long format that begins with ‘’.

Sender Policy Framework (SPF)

Some emails with an email address actually originate from outside of Temple or from an internal application (other than Exchange, Gmail, Listserv or Xerox Printers).

If your department sends emails that fall under one or more of these conditions, the email must comply with Temple's Sender Policy Framework (SPF). Otherwise, they will not be delivered.

To learn more, see the Sender Policy Framework page.

Safe Sender List

ITS uses spam filters to block suspicious emails from getting through to the university. In certain rare occasions, ITS allows for exceptions to this process by adding an email address to a safe sender list.

To qualify for this exception, the request must undergo a thorough security review, showing that the sender is highly trusted and that the emails need immediately delivery. One such example, would be TUalerts.

Modern Authentication

On April 13, 2020, ITS disabled access to Temple email accounts via legacy (or basic) authentication protocols. This action was taken primarily for security reasons, but also in anticipation of similar controls to be implemented by both Microsoft and Google

The problem with legacy authentication is that it allows access to Temple mail systems via outdated protocols that bypass access controls, such as Single Sign On (SSO) and Multi Factor Authentication (MFA). Hackers can use these protocols, along with compromised credentials, to target email account holders with phishing attacks from within Temple's own email systems.

Although you can no longer can set up new connections to your Temple email account with email clients that do not support modern authentication (or OAuth2), previously established connections will continue to maintain access until ITS gradually migrates them to modern authentication.

If you are experiencing any issues accessing your email, please contact the Help Desk at or by calling 215-204-8000.

Clients that support Modern Authentication or OAuth2
Mobile Devices

  • Gmail mobile app
  • Outlook mobile app
  • iOS Mail app
  • Android Mail app


  • Outlook desktop client (version 2016 and above for Exchange)
  • Outlook desktop client (version 2019 update 1812 and above for Gmail)

Web Access

Submit a Request

Departments can request the following email services through the website:

  • Disable the [EXTERNAL] tag for senders that should appear as internal to Temple
  • Register a vendor's fully qualified domain name or IP address as authorized to send on behalf of Temple per the Sender Policy Framework
  • Review an email address to be whitelisted to bypass the university spam filters
