I used pop peeper with my Telecom account (POP) "Alice" but unfortunately reading using pop peeper the email is deleted soon after is not possible recover this email that has attached a .zip multi photo file

I haven't send the command "delete" I have only read this email.
I've tried to search directly in my Telecom account to recover this email from the bin but seems to be deleted forever is not possible recover this email.
This is not a problem for the photos but I want to let you know this bug.

Please let me know if this is a know problem.
Thanks
Best Regards
