A case study on building a mail archive with postfix
summary
Shows a working mail-archiving pipeline built around Postfix using the sender_bcc/recipient_bcc trick and a secondary collector Postfix server, plus IMAP sync tools like imapsync/mbsync to copy mailboxes. Finds one‑way IMAP sync is reliable but needs full backup (e.g. Bacula) because folder structure and deletes aren’t preserved; sync is roughly 4x faster than naive mailbox copy in tests. Covers timestamped hashes for integrity, GDPR deletion challenges, and real configuration steps that actually work.
