Perbaiki Tanggal Migrasi imapsync di Outlook
Mengapa Migrasi imapsync Menampilkan Tanggal yang Salah di Outlook
imapsync is an open-source command-line tool popular among system administrator for server-to-server IMAP kotak surat synchronization. imapsync includes a --syncinternaldates flag designed to preserve the original INTERNALDATE selama migrasi. Namun, even when this flag is used, server email tujuan adds its own header Received to each uploaded message, and this header carries the stempel waktu migrasi.
Outlook does not rely solely on INTERNALDATE for tampilan tanggal. Outlook's "Received" column is derived from the topmost header Received in the email. Even if imapsync successfully preserved the INTERNALDATE using --syncinternaldates, the new header Received added by server tujuan overrides the date that Outlook displays. Administrators who believed they had protected the dates by using the correct imapsync flags discover that Outlook still shows the tanggal yang salah.
This behavior catches many experienced administrator by surprise. The imapsync documentation focuses on INTERNALDATE preservation, leading administrator to assume that --syncinternaldates is sufficient. In practice, the header Received issue is a separate problem that --syncinternaldates does not address, karena the header Received is added by server tujuan after imapsync completes its upload, outside of imapsync's control.
Bagaimana Hal Ini Mempengaruhi Outlook
Setelahn imapsync migration, Outlook menampilkan tanggal migrasi in the "Received" column for setiap email. Even when --syncinternaldates was used and the IMAP INTERNALDATE is technically correct on the server, Outlook parses the header Receiveds and menampilkan topmost one, which is the stempel waktu migrasi. The result is a kotak surat where setiap email appears to have arrived on the same day.
The frustration is compounded karena administrator can verify on the server IMAP that the INTERNALDATE is correct, yet Outlook still shows the tanggal yang salah. This leads to hours of troubleshooting on the Outlook side (reinstalling profiles, clearing caches, rebuilding OST files) that never resolve the issue karena the root cause is in the email headers, not in Outlook's local configuration. The only fix is to remove the migration header Received from each email at the tingkat server.
Pertanyaan yang sering diajukan
I used imapsync --syncinternaldates but Outlook still shows the tanggal yang salah. Why?
The --syncinternaldates flag preserves the IMAP INTERNALDATE on the server, but it cannot prevent server tujuan from adding a new header Received. Outlook reads the topmost header Received for its tampilan tanggal, which contains the stempel waktu migrasi. The INTERNALDATE and the header Received are two separate date sources.
Can I fix imapsync dates by editing the header Receiveds manually?
Technically, you would need to download each email, edit the headers, delete the original, and re-upload with the correct INTERNALDATE. For anything more than a handful of emails, this is impractical. Redate.io automates this entire process with built-in verification.
Does Redate.io work with any server IMAP used with imapsync?
Ya. Redate.io supports any standard server IMAP. Whether the destination was Dovecot, Courier, Exchange, or any other IMAP-compatible server, Redate.io can connect and fix the dates.
