A method for managing delivery of messages, each message being associated, via information relating to its origin, with a given emitting component that is to send the message and is associated, via information relating to its destination, with a plurality of given destination servers to which the message is to be sent, in a computing infrastructure, characterised in that it includes the following steps for each message to be delivered: - Simultaneously sending the message by an emitting component of the computing infrastructure, to each server (202-1, 202-2) of a plurality of destination servers of the computing infrastructure; - For each server (202-1, 202-2) of the plurality of destination servers having received the message sent and having stored the message received in its memory: ∘ Calculating, by the server (202-1, 202-2), a signature specific to the message received, the signature calculated being identical for each server (202-1, 202-2); ∘ Sending, by the server (202-1, 202-2), the signature calculated to a synchronisation component; ∘ Receiving the signature sent and querying a signature database by the synchronisation component: ▪ If a first condition according to which the signature received is not stored in the signature database is verified, storing the signature received in the signature database and sending an instruction to store or transmit the message received to the server (202-1, 202-2) by the synchronisation component; ▪ Otherwise, sending, by the synchronisation component, an instruction to delete the message received and the signature calculated to the server (202-1, 202-2). - Simultaneously sending the message by an emitting component of the computing infrastructure, to each server (202-1, 202-2) of a plurality of destination servers of the computing infrastructure; - For each server (202-1, 202-2) of the plurality of destination servers having received the message sent and having stored the message received in its memory: ∘ Calculating, by the server (202-1, 202-2), a signature specific to the message received, the signature calculated being identical for each server (202-1, 202-2); ∘ Sending, by the server (202-1, 202-2), the signature calculated to a synchronisation component; ∘ Receiving the signature sent and querying a signature database by the synchronisation component: ▪ If a first condition according to which the signature received is not stored in the signature database is verified, storing the signature received in the signature database and sending an instruction to store or transmit the message received to the server (202-1, 202-2) by the synchronisation component; ▪ Otherwise, sending, by the synchronisation component, an instruction to delete the message received and the signature calculated to the server (202-1, 202-2). ∘ Calculating, by the server (202-1, 202-2), a signature specific to the message received, the signature calculated being identical for each server (202-1, 202-2); ∘ Sending, by the server (202-1, 202-2), the signature calculated to a synchronisation component; ∘ Receiving the signature sent and querying a signature database by the synchronisation component: ▪ If a first condition according to which the signature received is not stored in the signature database is verified, storing the signature received in the signature database and sending an instruction to store or transmit the message received to the server (202-1, 202-2) by the synchronisation component; ▪ Otherwise, sending, by the synchronisation component, an instruction to delete the message received and the signature calculated to the server (202-1, 202-2). ▪ If a first condition according to which the signature received is not stored in the signature database is verified, storing the signature received in the signature database and sending an instruction to store or transmit the message received to the server (202-1, 202-2) by the synchronisation component; ▪ Otherwise, sending, by the synchronisation component, an instruction to delete the message received and the signature calculated to the server (202-1, 202-2).
