Abstract

Selon certains modes de réalisation, la présente invention se rapporte au domaine technique des communications. L'invention concerne un procédé de synchronisation de courriels et un terminal, permettant une charge réduite de ressources pour un client de courriel et, en même temps, de fournir au client de courriel de l'efficacité dans la transmission et dans la réception de courriels. Une solution spécifique comprend les étapes suivantes : un client de courriel détermine, en fonction d'un premier identifiant, si un premier courriel est sauvegardé dans un premier serveur, le premier identifiant étant un identifiant de courriel attribué au premier courriel par le client de courriel et servant à identifier de manière unique le premier courriel ; lorsque le premier courriel est sauvegardé dans le premier serveur, le client de courriel ne transmet pas le premier courriel au premier serveur ; et lorsque le premier courriel n'est pas sauvegardé dans le premier serveur, le client de courriel transmet le premier courriel au premier serveur, le premier courriel portant le premier identifiant.
