I’m forwarding DMARC reports to a centralized Tape app within a customer’s organization, using the ‘Public email address’ functionality. These emails are routed through the company’s main email server.
The server logs indicate that the emails are successfully sent to Tape, with detailed confirmations of delivery. However, the messages are not appearing in the app.
Interestingly, if I send an email directly from my personal address to the app, it works as expected. This suggests that the issue might be specific to how the messages are processed when sent via the company’s mail server.
It’s confusing that the server log reports successful delivery, yet the app does not display the emails. I’d appreciate any help in identifying where the discrepancy lies.
Can you send the email to your email, and then forward to the public tape email. Just to see if that works.
This will help troubleshoot and potentially provide a workaround until everything is resolved.
I have not looked at a public email address and tape and quite some time and I’m on my phone so I’m going for memory. I wonder If there are any characters in the tape email address that the server is stripping out?
What’s puzzling is that it worked when I initially set it up at the beginning of 2025. It stopped functioning around May 2025. That’s why I don’t believe the issue is related to the email format or the attachment itself. Also, when I forward the same email to myself, I can then send it to Tape without any issues.
That’s interesting. Do you have access to a different domain on the same server? Try sending from there to further confirm it’s not isolated to the original domain and Tape.
I hate chasing email bugs because of all the moving parts.
That does indeed sound like strange behavior, especially since nothing was changed on your end and it suddenly stopped working. Also, thanks a lot, @1F2NS, for jumping in and helping narrow things down!
We’ll also do a more detailed analysis on our end. We actually haven’t touched anything in our internal email modules or infrastructure recently either, which makes this all the more puzzling. But as we all know, email reception can be quite tricky - there are a lot of moving parts involved, and it’s often unclear what exactly causes issues like this.
As @1F2NS suggested, we’ll dig into the details and follow up here as soon as we know more.
