It is since yesterday that I cannot access the Murena.io webmail and the server reply: time out. Yesterday, I changed the password but for a little while it was working. Obviously the smartphone started to create issues after that because the old password was changed.
Is there a feature that blocks access when too many failed access tries are detected? If yes, this is a bug. Whatever the access failed attempts are, as long as they are carried on with the same password (hash), they should count as just one attempt because it cannot be a brute force attack but just a misconfigured or yet updated device.
Someone can provide some insight about this service downtime? Is it just my account or is it happening to everybody?
Not able to see any issues in sending or receiving mail on the site. If you are still facing issues you can send a mail to helpdesk@e.email and have the infra team check for issues with your account.
In the meantime I had deleted all Murena accounts from my /e/OS smartphone. After your answer, I have activated the Two Factors Authentication and noticed few problems:
the QR code for app/device authentication cannot be read by the smartphone murena.io configuration settings menu because this functionality is missing
using the app/device username/password to configure the murena.io account on the smartphone, the e-mail fails to authenticate and it needs the main password
once I have configured the 2FA, using the username/password login SHALL NOT work anymore also for the SSL/IMAP server but it still works
About the #3, it is also explained into the 2FA page:
Warning: The IMAP account is not protected with 2FA
