The academic messaging system of Aix-Marseille serves as the official channel for tens of thousands of agents. Creating a professional signature on this webmail raises a measurable question: what technical and regulatory elements separate a functional signature from a poorly formatted one that disintegrates on mobile or violates the academy’s graphic charter? This article compares the parameters to master and the frequent discrepancies between what agents produce and what academic standards expect.
Plain text or HTML signature: a comparison of formats on the academic webmail
| Criterion | Plain text signature | HTML signature |
|---|---|---|
| Mobile compatibility (ENT, smartphone, tablet) | Optimal, no risk of broken display | Variable depending on the recipient’s mail client |
| Insertion of the academic logo | Impossible (no embedded image) | Possible, but risk of being blocked by anti-spam filters |
| Compliance with the national graphic charter | Partial (typography and order respected, no logo) | Complete if the template follows ministerial guidelines |
| Message weight | Negligible | Heavier due to images encoded in base64 or linked |
| Accessibility (screen readers) | Total | Depends on the quality of alt tagging on images |
The academic webmail Aix-Marseille (Roundcube / Zimbra depending on the deployed version) manages both formats. However, a signature consisting of only an image is not recommended as it becomes unreadable on mobile clients and in the ENT, where images are often blocked by default.

To create a professional signature on the Aix-Marseille messaging system, the standard path goes through the Preferences menu and then the Signatures section of the webmail. This process, documented by the Mon Aide Numérique platform of the ministry, also allows for managing multiple signatures according to use (function, institution, correspondence with families).
Academic signature charter: the constraints that the webmail does not verify
Since 2023-2024, the ministry has offered a unified national tutorial for creating signatures in academic webmails, including that of Aix-Marseille, via the Mon Aide Numérique platform. This framework sets a precise order for the displayed information.

The Corsican academy, in June 2025, disseminated an official support imposing a homogeneous graphic model: standardized academic logo, mention of the French Republic, mandated typography, strict order (name, function, institution, contact details). This formalization serves as a signal for the agents of Aix-Marseille, as the national framework tends toward standardization.
The webmail does not block a non-compliant signature. No automatic control verifies compliance with the charter. It is up to the agent to ensure that their signature adheres to the guidelines. The most frequent discrepancies concern three points:
- The addition of personal images, quotes, or slogans, explicitly prohibited by recent academic charters
- The inversion of the order of information (contact details before the name, missing function)
- The use of a fancy font not available on the recipients’ devices, which causes a fallback to a default font and breaks the layout
Technical settings in the Aix-Marseille webmail: path and options
Access to the webmail is through the PACA academic region portal. Once logged in with their academic credentials, the agent accesses the messaging interface where the Preferences section groups the signature settings.
In this section, the input field accepts formatted text. The “default signature” setting automatically associates a signature with each new message. Without this activation, the signature does not insert, and the agent must select it manually for each send.
The webmail allows the creation of multiple distinct signatures. This feature is useful for agents who hold multiple functions or correspond with different audiences (colleagues, families, institutional partners). Each signature can be named for easier selection.
Management of IMAP and SMTP servers and impact on the signature
Agents who configure their academic messaging on an external client (Thunderbird, Outlook, mobile app) must provide the settings for the incoming IMAP server and the outgoing SMTP server with STARTTLS encryption. The signature created in the webmail does not synchronize with these third-party clients.
Each mail client requires its own signature configuration. An agent who uses both the webmail and a mobile app must therefore create and maintain two distinct signatures, ensuring their consistency.
Responsive signature: accessibility rules ignored by the majority of agents
Multi-device consultation (PC, smartphone, tablet) imposes technical constraints that most tutorials do not detail. A signature that displays correctly on a desktop screen can become unreadable on a phone screen if it relies on a fixed-width HTML table.
Best practices to ensure readability on all devices:
- Limit the signature to four or five lines of text, without multiple columns
- Avoid heavy images or high-resolution logos that slow down loading on mobile connections
- Use standard web fonts (Arial, Verdana, Georgia) that display predictably across all systems
- Test the display by sending an email to oneself on a smartphone before finalizing the signature
A signature longer than six lines loses readability on mobile. The compact format, limited to the name, function, institution, and a phone number, remains the most reliable across all devices used in the Aix-Marseille academy.
The protection of personal data adds a layer of vigilance. A personal phone number has no place in an academic signature. Only professional contact details (direct line of the institution, academic email address) should be included, in accordance with data protection recommendations in professional messaging.
