Email with RMS two-factor code undelivered

Dear Assistance,

As instructed during our phone call a few minutes ago, we are writing to report an issue with accessing our RMS account.
We are from Italy and are experiencing an issue receiving the two-factor authentication code email. Since at least February 11, 2026, the email server provider has not been forwarding these emails to us. The provider’s assistance states that some IP addresses used in these emails (e.g., 69.169.224.13) are now blacklisted. Indeed, this is confirmed, e.g., on AbuseIPDB if checking the indicated IP.
As such, the provider claims that those emails cannot be delivered and has not offered any way to solve the issue.

As RMS is vital to managing our field-deployed systems, we need to resolve this issue. One option is to move the RMS account email to a different address, such as a Gmail address. How can this be done safely?
We use a single company-wide account; nevertheless, we love the Teltonika products, and some of us also have a private RMS account (e.g., with a registered email address on Outlook or Gmail): the two-factor authentication with those emails still works as expected, which is why we would like to proceed with porting the company’s account.

Please help us solve this issue.
Stefano
