Optional: Setting up email routing

TIP: Adding Office 365 already sets up the required email routing in NoSpamProxy Cloud and optionally the automatic user import. If you want to integrate Office 365 in Cloud or have already integrated it, you can skip this chapter. For further information, see Integrating Office 365.

Adding corporate email servers

NOTE: Corporate email servers may use a corporate domain in the 'MAIL FROM' address. See Adding domains.

Via SMTP Authentication (SMTP-Auth)

NOTE:

  • A TLS-secured connection is required to add servers with SMTP authentication.

  • NoSpamProxy supports the AUTH and LOGIN authentication methods.

  1. Go to Configuration > Email routing > Corporate email servers.
  2. Click Add.
  3. Select Authenticated Server.
  4. Note down the user name.
  5. Copy the specified password to the clipboard, write it down and click Next.
  6. Click Finish.
  7. Configure the user name and password in the settings of your third-party server product.

Via SPF entry

  1. Go to Configuration > Email routing > Corporate email servers.
  2. Click Add.
  3. Select Sender Policy Framework (SPF).
  4. If necessary, restrict the email server to certain domains.
  5. Click Finish.
WARNING:

Domains and IP addresses that appear in the respective SPF record may use your corporate domains as the sender address. We therefore recommend the following:

  • Add only the entries that are absolutely necessary.
  • Use dedicated subdomains. This ensures that the service only uses these subdomains and that the main domain is reserved for the actual email server, usually an Exchange server. For better categorisation, it is helpful to create the subdomains based on the function, for example hr.example.com for the HR department, marketing.example.com for the marketing department or it.example.com for the IT department.
  • Restrict the SPF-protected local address to the required subdomain or domain.
  • Always add -all to the SPF entry to exclude any other IP addresses from sending.

Integrating an Office 365 host

For information about how to integrate Office 365 hosts, see Integrating Office 365.

Configuring the connector for outbound emails.

To send email through NoSpamProxy Cloud, you must add NoSpamProxy Cloud as a smart host in your local mail server (for example, Microsoft Exchange).

You will need

  • the address of the NoSpamProxy smarthost displayed under Your NoSpamProxy smarthost and
  • the username and password you received when you added the corporate email server.

Configuring the connector for inbound emails.

  1. Go to Configuration > Email routing > Inbound email delivery
  2. Click Add.
  3. Enter a name for the connector, determine its cost and click Next.
  4. Click Add and specify the host name, port, and optionally a user name and password for your third-party server product, then click Save and then Next.
  5. Determine the DNS routing restrictions for this connector.
  6. Click Finish.
