A direct access proxy is operative to reconcile the email contents of external email sources with the email contents of user devices through the use of lists of unique email identifiers (UIDs). A Partition Database returns UID lists reflective of the UIDs of email messages previously received from the external email source and forwarded to a network server of the system (forwarded UID lists). A memory cache external to the direct access proxy and its corresponding Partition Database returns forwarded UID lists. The direct access proxy determines the data reliability of the Partition Database and memory cache, and obtains forwarded UID lists from the memory cache when it determines that the memory cache is at least as reliable as the Partition Database."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Caching email unique identifiers","description":"Accessing, via an end user device, email messages of an external mail source.
