Causes for ticket suspension

Return to top


  • Moshe Gottlieb

    We integrate with a system called where our users can leave messages or chat with our support team. All chat transcripts or offline messages are sent to zendesk to be created as tickets. As of the last few days these are all ending up as suspended tickets with the reason "Detected email as being from a system user". But these are not coming from emails like postmaster or the like. The from address is set as the user's email address who is sending the request.

    We are losing tickets as a result! please advise

    Hi Moshe,

    Emails from system users are always suspended and it is a hard system rule that cannot be disabled. Since you have confirmed that it is not coming from a system user, I highly suggest that you collect ticket samples and reach out to our Customer Support for further investigation.

    Is there any way to determine as to why an email has been marked as spam? We have a substantial amount of suspended tickets and going through them 1 by 1 isnt a viable option.


    Any help would be amazing!

    Hi Sam.,

    Are you seeing a common spam reason on the ticket itself? If yes, please check if that falls under the causes discussed in this article and follow the suggested resolutions. If the issue persists after following the same, I suggest that you grab at least 5 tickets, and reach out to our Customer Support so they can dig deeper into your account.

    I wanted to share my workaround.

    We had the issue that Zendesk was setting a lot of email as Spam and there was no other way then to recover them manually. This is what I was told. 

    It worked by creating organizations and end users profiles to let Zendesk recognize those emails. 

    It would be ideal to add this information to the article, if you consider this working for you too.

    "Detected as email loop" - what is the threshold after which the mails from the same user are suspended?  Do we have the access to manage this limit? 

  • Alex
    Hello Navenkumar,
    We have a limit of 20 emails from the same user within an hour. Beyond that, the next 20 updates will be suspended. If more than 40 are received, all additional updates within that hour will be rejected (meaning they won't even create suspended tickets).
    There is no option to manage this limit, I'm sorry.
    You can find more information on how email loops are handled in our article About mail loops and Zendesk email

    Hello! Is there any way to permit the ticket creation of e-mails "Received from support address"? We have this issue in a client instance. A support address "X", as a sender ("from:"), sends an e-mail to another support address "Y" (receiver - "to:"). All these tickets are suspended.

    Hi Jeferson,
    Unfortunately there is no setting or anything along those lines available in Zendesk Support. If you have a support address added in your Email channel settings and that same email address is the requester on a ticket, the ticket will be suspended. If the original sender of a ticket is a unique end-user in your workflow, you may want to look into setting up an email redirect in your email client. Email redirects are different than forwarding in that redirecting preserves the header information so that the email appears to be from the original sender, not from address forwarding the email.
    In order for these these tickets to avoid being suspended, you will either need to remove the support address that's set as the requester from your Email settings or somehow change the email address these tickets are coming from. I hope this information helps!

    Hi all, 

    Is there a way to view the original email that has been suspended if one of our users is saying the email didn't come from then in out support email address?

    Thanks in advance 

  • Hiedi Kysther

    Hey Lucy Mills,

    Unfortunately, this is not possible if the email is suspended. But, you can view original email from your provider's mailbox. Remember, emails that were forwarded to Zendesk came from your mail provider's inbox. For reference: 

    I hope this helps! 

    Best regards,

    Hi Team! Is there anything in the works to let admins 'allow-list' certain addresses please? 

    We see more and more emails getting caught by 'Detected email as being from a system user' - but they're legit emails (yes, they're automated but need action from our teams).

    For example our accounts team in particular deal with a lot of invoices which come through from automated systems but can also then sometimes need replies. The emails are not coming from any of the examples in the table above - e.g. one comes from

    Is there any way to configure 'don't suspend this domain / this sender, deliver them as normal' anywhere please?

    Thank you!

    Hi Tim G

    Usually adding the email addresses in the allowlist would resolve the ticket suspensions. If the emails in the allowlist are still getting suspended, there may have been an x-header: included that could be causing the suspensions. By that time I would suggest creating a ticket with us so we can check the email logs to help identify what's causing the suspension.
