Mailbox

src/lib-storage/mail-storage.h and mail-storage-private.h describes mailbox API, among others. Mailbox life cycle often goes like:

  • mailbox_alloc() allocates memory for the mailbox and initializes some internal settings, but doesn't actually try to open it.

  • mailbox_open() opens the mailbox. Instead of opening a mailbox, you can also create it with mailbox_create().

    • If you're immediately syncing the mailbox, you don't need to open it, because it's done implicitly. This reduces your code and error handling a bit.
  • mailbox_close() closes and frees the mailbox.

There are a lot of functions to deal with mailboxes. The most important ones are:

  • mailbox_get_status() to get a summary of mailbox, such as number of messages in it.

  • Syncing: mailbox_sync_*() to synchronize changes from the backend to memory.

  • Transactions: mailbox_transaction_*() for transaction handling. All message reads and writes are done in a transaction.

  • Searching: mailbox_search_*() is used for searching messages. Even simple operations like "get all messages" go through this API, it'll then simply do "search all".

  • Saving: mailbox_save_*() and mailbox_copy() is used for saving/copying new messages to mailbox.
