4. G Suite Mail Management

4.1. Domain Name System(DNS)

DNS records that impact mail delivery

    MX Record

  • Mail Exchange (MX) records direct email to the servers hosting your user accounts. To set up Gmail if you have G Suite, you need to point your MX records to the Google mail servers. Multiple MX records can be defined for a domain, each with a different priority. If mail can't be delivered using the highest priority record, the second priority record is used, and so on.
  • TXT Record

  • A TXT record is a DNS record that provides text information to sources outside your domain, that can be used for a number of arbitrary purposes. G Suite uses TXT records for a variety of purposes such as domain verification and to implement email security measures such as SPF, DKIM, and DMARC which we will discuss later.
  • CNAME Record

  • A CNAME or Canonical Name record links an alias name to another true or canonical domain name. For instance, www.example.com might link to example.com. With G Suite services you use CNAME records to customize a Google service address or the address of a website built with Google Sites.

Other DNS record types

    A Record

  • An A or Address record (also known as a host record) links a domain to the physical IP address of a computer hosting that domain's services.
  • NS Record

  • Name server (NS) records determine which servers will communicate DNS information for a domain. Generally, you have primary and secondary name server records for your domain. When using G Suite you may configure NS records that point to Google servers for DNS queries.

4.2. Enhanching Email Security

SPF(Sender Policy Framework)

SPF record you are telling receiving mail servers which domains/servers are allowed to send mail on your behalf. Messages sent from other sources may be marked as spam

DKIM(DomainKeys Identified Mail)

helps prevent email spoofing on outgoing messages by adding an encrypted header to every message sent. Recipient servers decrypt this header using the DKIM record to confirm it's validity

DMARC(Domain-based Message Authentication)

prevent outbound spam messages using a Domain-based Message Authentication, Reporting, and Conformance (DMARC) policy. DMARC policies tell email servers how to handle messages that fail SPF/DKIM checks

4.3. Email Safety and End User Access

POP/IMAP access

allow users to connect desktop apps to Gmail

G Suite Sync for Microsoft Outlook

allow users to work with Gmail from Microsoft Outlook

Gmail offline access

4.4. Prevention of SPAM, Phising and Malware

  1. Be more aggressive, for strict filtering of email. (although this may result in valid messages being identified as spam)
  2. Bypass internal mail.
  3. Use approved sender lists

4.5. Compliance

A compliance rule can scan messages for

  • Attachment compliance: attachments of certain types
  • Content compliance: search for text content
  • Objectionable content: identify messages that contain words in a custom word lists that you define

When a message matches a compliance rule, you can

  • Reject it
  • Quarantine it
  • Deliver it with modifications

4.6. Mail Routing

  1. Gmail to scan your inbound mail for spam and compliance purposes, but store the mail on your external mail server
  2. Some users to receive mail in Gmail inboxes, and others to access mail from your local server (split delivery)

Direct delivery

This is the default setting and applies where your organization has all of it's users on G Suite. All messages are delivered directly to the Gmail inbox. If your environment is 100% G Suite you should not need to make changes to your mail routing settings in G Suite, however it is very useful to understand the options available to you as the administrator, so you should walk through this lesson and read the Help Center resources provided.

Split Delivery

Incoming messages are routed to either the Gmail inbox or another mail system. This method works well if some of your users use Gmail, and others use a different mail system. This is commonly used during a migration (or deployment) to G Suite.

Dual Delivery

his is used where you want to route messages to the Gmail inbox and another system. With dual delivery, incoming mail is delivered to a primary mail server first. The primary server delivers each message to the inboxes associated with it, then forwards all messages to a secondary mail server. The secondary server delivers the messages to the secondary server inboxes. This method is useful if you are trialling G Suite for a small number of users but you wish your existing mail system to retain a copy of all messages.

Outbound gateway

An outbound mail gateway server processes email messages before they’re delivered. Typically, these servers are used for archiving or spam filtering. The gateway server should be configured to accept and forward mail from G Suite mail IPs only to prevent spammers from using it as an open relay. It's also important that your SPF record contains the gateway address. DKIM will work but only if the gateway does not modify the message in any way.

An outbound gateway can also be defined using a routing setting which is preferred as routing settings offer much more flexibility over outbound gateway setting. The outbound gateway setting applies to everyone in the organization where as routing settings can be applied at the OU level. Routing settings can also be configured to use specific envelope filters and address lists. For example, you may only want to archive mail from your legal department. If this is the requirement you would use a routing setting to capture all outbound mail from the legal department only and route that via the gateway.

Recipient address map

This feature is also known as a virtual user table. It allows the administrator to reroute a message from one address to another address. Each entry in the address map consists of two email addresses; the original intended address and the address where the message should be routed to.

Inbound email journal acceptance to Vault

This feature allows you to use Google Vault to store messages from another mail platform.

Third party email archiving

This feature allows Gmail content to be archived in a third party archive system.

Non-Gmail mailbox

This setting is only for users whose mailboxes are located on an on-premise/non-Gmail mail server. It allows you to use Gmail's spam filtering and other G Suite features such as content compliance and mail routing but messages are delivered to the users external inbox. You must not turn this feature on for Gmail users as they will lose access to their Gmail inbox.

SMTP Relay service

If your organization uses a non-Gmail mail service, you can configure the SMTP Relay service to route outgoing mail through Google. You can use this setting to filter messages for spam and viruses before they reach external contacts. You can also apply G Suite email security and advanced Gmail settings to outgoing messages.

Don't confuse this with the Outbound gateway setting described above. In that setting, your users are using Gmail and you want to route all outbound mail through another SMTP server defined by the outbound gateway setting. Using the SMTP relay service, Google becomes the outbound gateway for your non-Gmail mail users.

Alternate secure route

You can use this setting to determine the route a message must take if it requires secure transport. For example, if you use a third-party encryption service, you can use the alternate secure route setting to route otherwise insecure traffic to it.
