What optional filters can I apply when exporting emails with Zimbra?

You can add `start` and `end` Unix timestamps to filter by date range, and a `query` parameter to search for keywords (e.g., `content:password`). The time values must be in milliseconds, and the query syntax follows Zimbra’s search tips. This allows targeted export of specific emails, as demonstrated in the [Zimbra SOAP API Development Guide 4 - Email Export and Folder Sharing](/news/zimbra-soap-api-development-guide-4-email-export-and-folder-sharing).
