Apr 15, 2018 Outlook includes a Junk Email filter.This filter cannot be updated by the end user and Microsoft stopped releasing updates for it in November 2016. For most users, setting the Junk email filter set to high is good enough, especially if their mail is also scanned by a server side anti-spam filter. Block a sender. When you no longer want to see messages from someone, you can block a sender. Right-click a message from the sender you want to block, and then click Junk Block Sender. The blocked person can still send you mail, but if anything from his or her email address makes it to your email account, it’s immediately moved to the Junk Email folder. Jun 04, 2017 Why don't we have a 'Block Sender's Domain' right-click option? There are quite a few people out there who add every address they receive spam from to the Block List. Obviously, that is not the way to go either but the 'damage' is less than directly blocking an entire domain. Is there something Outlook users can do to block entire.
- Sep 11, 2018 This article explains how to configure Outlook Junk Mail Filter properly to stop as many junk emails as possible. How to keep the filter up to date, take a good message out of the Junk folder and ensure that no legitimate e-mails gets there.
- Nov 15, 2019 Outlook Mail on the web makes it easy to block messages by individual senders from showing up in your inbox folder. For even more.
- Sep 07, 2019 4 Junk/Spam servers can easily be identified and blocked at the 'server-level' by entities like Microsoft-but Microsoft does not do this-Microsoft leaves it up to the user to block junk/spam individually 'by-the-piece' rather than doing it themselves by blocking email servers disseminating spam through outlook.live, hotmail.com etc.
Applies to: Exchange Server 2013
In Microsoft Exchange Server 2013, safelist aggregation refers to anti-spam functionality shared across Microsoft Outlook and Exchange. This functionality collects data from the anti-spam Safe Recipients Lists, Safe Senders Lists, Blocked Senders Lists, and contact data that Outlook users configure, and makes this data available to the Exchange anti-spam agents.
When you enable and correctly configure safelist aggregation, the Content Filter agent passes safe email messages to the enterprise mailbox without additional processing. Email messages that Outlook users receive from contacts that those users have added to their Outlook Safe Recipients List or Safe Senders List or have trusted are identified by the Content Filter agent as safe. An Outlook contact is a person, inside or outside the user's organization, about whom the user can save several types of information, such as email and street addresses, telephone and fax numbers, and Web page URLs.
In Exchange 2013, the safelist aggregation process also allows the Sender Filtering agent to block incoming messages from the per-recipient Block Senders List.
Safelist aggregation can help reduce the instances of false-positives in anti-spam filtering performed by Exchange. In the context of spam filtering, a false-positive occurs when a spam filter incorrectly identifies a legitimate message as spam.
For organizations that filter hundreds of thousands of messages from the Internet every day, even a small percentage of false-positives means that users might not receive many messages that were incorrectly identified as spam if those messages were quarantined or deleted.
Safelist aggregation is likely the most effective way to reduce false-positives. In Outlook 2010 or newer versions, users can create Safe Senders Lists. Safe Senders Lists specify a list of domain names and email addresses from which the Outlook user wants to receive messages. By default, email addresses in Outlook Contacts and in the Exchange global address list are included in this list. By default, Outlook adds all external contacts to which the user sends mail to the Safe Senders List.
Information stored in the Outlook user's safelist collection
A safelist collection is the combined data from the user's Safe Senders List, Safe Recipients List, Blocked Senders List, and external contacts. This data is stored in Outlook and in the Exchange mailbox.
The following types of information are stored in an Outlook user's safelist collection:
Safe senders and safe recipients: The From message header indicates a sender. The To field of the email message indicates a recipient. Safe senders and safe recipients are represented by full SMTP addresses, such as masato@contoso.com. Outlook users can add senders and recipients to their safe lists.
Blocked senders: Just like safe senders, users can block unwanted senders by adding them to their Blocked Senders Lists.
Safe domain: The domain is the part of an SMTP address that follows the @ symbol. For example, contoso.com is the domain in the masato@contoso.com address. Outlook users can add sending domains to their safe lists.
Important
By default, Exchange doesn't include the domains during safelist aggregation. However, you can configure safelist aggregation to include the safe domain data for the anti-spam agents. For more information, see Configure Content Filtering to Use Safe Domain Data.
External contacts: Two types of external contacts can be included in the safelist aggregation. The first type of external contact includes contacts to whom Outlook users have sent mail. This class of contact is added to the Safe Senders List only if an Outlook user selects the corresponding option in the Junk Email settings in Outlook 2007.
The second type of external contact includes the users' Outlook contacts. Users can add or import these contacts into Outlook. This class of contact is added to the Safe Senders List only if an Outlook user selects the corresponding option in the Junk Email Filter settings in Outlook 2010 or Outlook 2007.
How Exchange uses the safelist collection
The safelist collection is stored on the user's Mailbox server. A user can have up to 1,024 unique entries in a safelist collection. Exchange 2013 has a mailbox assistant, called the Junk Email Options mailbox assistant, which monitors changes to the safelist collection for your mailboxes. It then replicates these changes to Active Directory, where the safelist collection is stored on each user object. When the safelist collection is stored on the user object in Active Directory, the safelist collection is aggregated with the anti-spam functionality of Exchange 2013 and is optimized for minimized storage and replication. Exchange uses the safelist collection data during content filtering. If you have a subscribed Edge Transport server in your perimeter network, the Microsoft Exchange EdgeSync service replicates the safelist collection to the Active Directory Lightweight Directory Services (AD LDS) instance on the Edge Transport server.
Important
Although the safe recipient data is stored in Outlook and can be aggregated into the safelist collection, the content filtering functionality doesn't act on safe recipient data.
Hashing of safelist collection entries
Safelist collection entries are hashed (SHA-256) one way before they are stored as array sets across three user object attributes, msExchSafeSenderHash, msExchSafeRecipientHash, and msExchBlockedSendersHash, as a binary large object. When data is hashed, an output of fixed length is produced, and the output is likely to be unique. For hashing of safelist collection entries, a 4-byte hash is produced. When a message is received from the Internet, Exchange hashes the sender address and compares it to the hashes stored on behalf of the Outlook user to whom the message was sent. If the sender matches the safe senders hash, the message bypasses content filtering. If the sender matches the blocked senders hash, the message is blocked.
One-way hashing of safelist collection entries performs the following important functions:
Minimizes storage and replication space: Most of the time, hashing reduces the size of the data hashed. Therefore, saving and transmitting a hashed version of a safelist collection entry conserves storage space and replication time. For example, a user who has 200 entries in his or her safelist collection would create about 800 bytes of hashed data stored and replicated in Active Directory.
Renders user safelist collections unusable by malicious users: Because one-way hash values are impossible to reverse-engineer into the original SMTP address or domain, the safelist collections don't yield usable email addresses for malicious users who might compromise an Exchange server.
Enabling safelist aggregation
Safelist aggregation is enabled by default in Exchange 2013. Unlike in Exchange Server 2007, you don't need to manually run the Update-SafeList cmdlet to hash and write the safelist collection data to Active Directory. In Exchange 2013, the safelist collection data is written to Active Directory by the Junk Email Options mailbox assistant.
To make the safelist aggregation data in Active Directory available to Edge Transport servers in the perimeter network, you need to install and configure the Microsoft Exchange EdgeSync service so that the safelist aggregation data is replicated to AD LDS.
You can still manually run safelist aggregation by using the UpdateSafelist cmdlet. However, you need to be mindful of the network and replication traffic that may be generated when you run this command. Running Update-Safelist on multiple mailboxes where safelists are heavily used may generate a significant amount of traffic. We recommend that if you run the command on multiple mailboxes, you should run the command during off-peak, non-business hours.
The Update-SafeList cmdlet reads the safelist collection from the user's mailbox, hashes each entry, sorts the entries for easy search, and then converts the hash to a binary attribute. Finally, the Update-SafeList cmdlet compares the binary attribute that was created to any value stored on the attribute. If the two values are identical, the Update-SafeList cmdlet doesn't update the user attribute value with the safelist aggregation data. If the two attribute values are different, the Update-SafeList cmdlet updates the safelist aggregation value.
