Outgoing Anti-Spam Enhancement
  1. I get this message when I sent out email. "Your email has been identified by SingNet as a potential spam. Your email was not sent."

    Why are my outgoing emails classified as potential spam?

    All outgoing emails from SingNet users are subject to Anti-spam scanning at our email gateway. Your outgoing email will be rejected immediately with this pop up message if it is detected as potential spam at our email gateway. The objective of this measure is to ensure that our users' email accounts will not be blacklisted by other mail servers as spam mails due to the few who misuse the SingNet email service.

  2. What can I do to prevent my emails from being classified as potential spam?
    Please refrain from sending emails, which contains product advertisement and phishing content or unsolicited in nature.

  3. Why are our emails being scanned for spam?
    SingNet is making an effort to reduce spam. We filter outgoing spam to ensure that our users are not blacklisted by other ISPs and email service providers. Mail servers that have been blacklisted will cause all outgoing emails to bounce and this will impact all users. Most ISPs and email service providers do have policies in place that prevent users from sending spam (though not all of these policies may be properly enforced).

  4. Is this something new to the SingNet email gateway?
    No, this is an enhancement to the previous outgoing spam solution. Previously we blocked potential outgoing spam by blocking all IP addresses from other local ISPs and ST Mobile to limit spam, which might have resulted in difficulties in using your SingNet emails. We have since implemented a more robust method of checking for spam, without these limitations.

  5. My emails are being scanned. Is my privacy compromised?
    No, SingNet respects your privacy. Emails are scanned by our servers through a set of heuristics and not by human intervention.

  6. How can I enjoy the new Anti-Spam enhancement?
    No action is required as long as your Email Client's Outgoing mail (SMTP) server is configured as

  7. Can this outgoing anti-spam enhancement filter out all the spam emails sent by SingNet users?
    As there is no absolute definition of what is considered spam, SingNet's outgoing anti-spam enhancement may not be able to filter off 100% of all spam mails, but it should be able to filter out the most common forms of it.

  8. With the implementation of this enhancement, why are there still recipients' who receive spam mails from my email address?
    The recipients might be receiving spoof mails which are not sent out from SingNet email gateway.

  9. Should I terminate my current subscription of Anti-spam service with the implementation of this enhancement?
    Please do not terminate your current subscription of Anti-spam service. It's purpose is to protect against incoming spam whereas this enhancement purely protects SingNet users from sending out spam.

  10. Can I terminate or unsubscribe from this outgoing anti-spam enhancement?
    As this enhancement is meant to protect all users, it cannot be terminated.
