What To Do:
If you receive mail from a sender you recognize and you cannot unsubscribe, you can BLOCK them and move the mail to your JUNK folder
You are protected against spam under Canada’s anti-spam legislation (CASL). Learn about the legislation as well as how to protect yourself from spam and how to report it when necessary.
If you have not given permission to receive unwanted mail from a sender, you can also report them to the Canadian Radio-television and Telecommunications Commission.
Phishing is a type of online attack in which an attacker — using both technological and psychological tactics — sends one or more individuals an unsolicited email, social media post, or instant message designed to trick the recipient into revealing sensitive information or downloading malware.
Phishing attacks can be generic or customized and can target both individuals and entire organizations. Attacks that target a specific individual or organization are commonly referred to as spear phishing attacks.
The main goal of a phishing attack is to get the individual to do something that compromises the security of their system and/or potentially their organization. To stop attackers from achieving this, when you receive a suspicious email:
Phishing messages can range from very basic to highly sophisticated. Common “red flags” or indicators include:
If you think you have been phished or hacked, don’t be embarrassed. The best thing to do is report to the UTS Service Desk.
All suspicious messages must be reported to is-spam@mcmaster.ca and the message should be deleted from your inbox and your deleted folder. Reporting phishing attempts and suspicious messages helps keep the McMaster community safer.
Then, delete or move the emails to JUNK.

McMaster Community Members who have experienced unwelcome comments or conduct by another person are encouraged, although not obliged, to make it known to the other person that their behaviour is unwelcome.
In situations where it is believed that addressing the other person could lead to an escalation of the comment or conduct or safety risks, this approach is not recommended. If the problem is not resolved, or if you feel you cannot respond directly to the other person, notify an appropriate Supervisor, or contact HR (staff) or Campus Police (staff and students).

Use a RULE to move the emails to Junk or keep them in a separate folder for investigation. Rules can also help filter out specific words/names that repeatedly come from different or hidden email addresses.
Rules allow you to move, flag, and respond to email messages automatically. You can also use rules to play sounds, move messages to folders, or display new item alerts.
The easiest and most common rule to create is one that allows you to move an item from a certain sender or with certain words in the subject line to another folder. You can create this rule directly from a message you’ve already received.
No one likes spam or junk email. The Outlook Junk Email Filter doesn’t stop the delivery of junk email messages, but does the next best thing—it moves suspected spam to the Junk Email folder.

The cloud is just as secure as on-premise. In fact, the cloud solution comes with features that will enable us to make it even more secure such as conditional access, spam controls, and multi-factor authentication. Moving forward, McMaster University will look to take advantage of these advanced features.

Beginning in February, Google and Yahoo are implementing new requirements for bulk email senders to reduce spam for Gmail users. Other email service providers, such as Microsoft, may soon follow suit.
If you or your team use an ‘@mcmaster.ca’ email address to send mass email to EXTERNAL non-McMaster email accounts (ex. Gmail or Yahoo) via a third-party service (ex. Mail Chimp, Constant Contact), those emails sent to recipients with Gmail and Yahoo accounts may be blocked starting in February 2024.
To avoid potential impact, it is recommended that you follow these steps:
You are only required to take action at this time if you send bulk email using an ‘@mcmaster.ca’ account via third party services (ex. Mail Chimp) to external, non-McMaster recipients. Otherwise, NO ACTION is required.
If you have any questions or concerns, please contact the UTS service desk.
Email authentication is a way of verifying that an email sender is who they claim to be. It helps prevent spam, phishing, and spoofing, which are common techniques used by cybercriminals to trick recipients into opening malicious emails or revealing sensitive information.
Email authentication is especially important for bulk email senders, who send large volumes of emails to internal or external recipients via a third-party service such as Mail Chimp or Constant Contact.
At McMaster University, there are two main methods to authenticate a third-party bulk mailing account:
DKIM is a technical standard that authenticates you as a legitimate McMaster sender. This option will allow you to use your @mcmaster.ca email address as the sender of your bulk emails.
To do this, you will need to follow these steps:
This option will allow you to send your bulk emails without authenticating your account with UTS, but you will not be able to use your @mcmaster.ca email address as the ‘From’ address in the email. Instead, you will have to use an email address that matches the domain of your service provider, such as yourname@constantcontact.com. To do this, you will need to work directly with your email account or service provider.
