Monaco Telecom has issued a final reminder to users of @monaco.mc and @libello.com email addresses to update their mailbox settings before 15th September 2025, or risk losing the ability to send emails.
From 15th September, outgoing mail servers that do not comply with international security standards will be permanently shut down. This move comes amid rising phishing attacks, with Monaco Telecom strengthening its infrastructure to safeguard users against risks such as identity theft, password breaches and banking fraud.
How to check and update settings
All users who access their mailbox through software such as Outlook, Apple Mail or Thunderbird must ensure their accounts are configured with Monaco Telecom’s secure servers across every device they use. A dedicated support page – monaco-telecom.mc/config – provides video tutorials and a ‘Check’ tool that allows users to confirm their settings with a single test email.
Support for customers
Since June, more than 1,300 clients have sought assistance either via Monaco Telecom’s customer service or at the Maison du Numérique. Users can book an appointment with an advisor (+377 92 26 92 26), contact customer service directly (+377 99 66 33 00), or consult the operator’s virtual assistant through its website or WhatsApp (+377 377 10 000). Customers who use Monaco Telecom’s Webmail exclusively do not need to take any action.
Operators stress shared responsibility
“Securing our clients’ data is one of our top priorities. Cyberattacks are now the leading threat facing email users,” said Martin Péronnet, Director General of Monaco Telecom. “We are reinforcing our infrastructure while supporting clients through this transition.”
Frédéric Fautrier, Director of Monaco’s Digital Security Agency, added: “The risks posed by malicious emails are significant, from stolen personal data to compromised banking details. Vigilance is essential, but it is equally important for operators to implement robust measures to protect their users.”
