Status types

In the following, the individual status types are explained by means of examples.

NOTE: This information is for basic understanding and does not necessarily cover every case.

  • Successful The email was successfully transmitted to the recipient.
  • Delivery failed An outbound email was rejected by the receiving system. In the "Delivery" tab, you can track the feedback from the receiving system.
  • Temporarily rejected The delivering email server receives a response and will make another delivery attempt after the configured interval.
    • Greylisting An inbound email has received at least 2 SCL points for violating our filters.
    • Recipient does not match the rule of the first recipient An outbound email is sent to different recipients and a certificate for encryption is not available for each recipient.
    • 32Guards A recently righted host is temporarily rejected for a short period of time to determine its reputation.
    • Service not reachable The Integrated Malware Scanner is usually configured as the only selected Malware-Scanner but is not reachable.
  • Permanently rejected The email was rated with at least 4 SCL points due to violation of our filters or rejected by Aktionen in NoSpamProxy.
  • Delivery pending The email is still being delivered and will be noted shortly with a different status depending on the result. Details can be found on the tab Delivery.
  • Multiple delivery states An email was sent to several recipients and noted with different results. Details can be found in the respective entry on the tab Delivery.
  • Accepted but not delivered The email is received but cannot be processed.
    • Outbound content filtering The stored content filter prohibits the attachment of the e-mail.
    • Encryption A rule with mandatory encryption is used; this was not possible for the recipient.
    • The sender has established a connection but has not transmitted an email body In this case, NoSpamProxy only sees the email envelope with sender and recipient, but cannot process the email. Often such a connection is created to validate an email address of a previously outgoing email and is intended to serve as an anti-spam measure. The process is known as callback verification.
    • De-Mail An attempt is made to deliver an email for which there is no configuration in NoSpamProxy to a De-Mail recipient.
  • Duplicate An email was delivered twice to NoSpamProxy. The loop (email loop) is prevented and the email is not delivered.
    • An inbound email is delivered by NoSpamProxy to the configured email server. However, this email does not end up in the recipient's mailbox, but the email server sends it back to NoSpamProxy again a few seconds after receiving the email.
    • An inbound email was sent twice with the same message ID from the same or different submitting systems. Each email must have a unique mail ID.
  • Put on hold Further actions are necessary for the email to be delivered successfully.
    • Content filter The email is stopped to process the attached files and then delivered with a second message track as a successful email. The action performed can be tracked in the Message Track on the Activities tab. You can track the successor of the email in the Message Track on the tab Relations.
    • PDF mail The outbound email is converted into a PDF document and encrypted because there is no S/MIME certificate for the recipient. The recipient must assign a password on the Web Portal; until then, the email remains in this status. After 5 days of no response from the recipient, an NDR to the sender follows.
    • Service not reachable The Integrated Malware Scanner cannot reach files that are to be uploaded to the Web Portal.
