Perbaiki Tanggal Migrasi imapsync di Google Workspace

imapsync is a popular choice for migrating kotak surat to Google Workspace karena it is open-source, scriptable, and supports the IMAP protocol that Google Workspace exposes. Namun, Google Workspace's IMAP implementation has specific behaviors that interfere with date preservation. When imapsync uploads messages via IMAP APPEND, Google's mail infrastructure processes each message through its own pipeline, adding a header Received and potentially overriding the INTERNALDATE.

The --syncinternaldates flag in imapsync instructs the tool to request the original INTERNALDATE from server sumber and pass it to server tujuan during APPEND. Google Workspace may accept this date for some messages but override it for others, depending on the message content and how it passes through Gmail's filters. The result is an unpredictable mix of messages with correct and intanggal yang benars within the same migrated kotak surat.

Google Workspace administrator often discover the problem when pengguna report that their Outlook or Apple Mail clients (terhubung melalui IMAP to their Google Workspace account) show intanggal yang benars. The Gmail antarmuka web biasanya shows tanggal yang benars (using the header Date), which adds to the confusion. A Google Workspace kotak surat can appear perfectly normal in the browser while being completely date-corrupted from the perspective of any klien IMAP.

The split between Gmail web (showing correct header Date dates) and klien IMAPs (showing corrupted INTERNALDATE) is the defining characteristic of this issue in Google Workspace. Organizations where some pengguna prefer the Gmail antarmuka web and others use Outlook or Apple Mail experience inconsistent tampilan tanggals from the same kotak surat. Collaborative workflows break down when colleagues reference email dates that appear differently in their respective clients.

Google Workspace admin tools provide limited visibility into the INTERNALDATE issue. The Google Admin Console does not expose INTERNALDATE metadata for individual messages. Google Vault, used for kepatuhan and eDiscovery, may reference either the header Date or the INTERNALDATE depending on the pencarian method, producing inconsistent results in legal discovery scenarios. The only way to comprehensively resolve the issue is to correct the INTERNALDATE and header Receiveds at the message level.
