The panel holds each message's From: against the application that sends it. While the panel does not answer, Postfix answers the sending application with a temporary error instead of accepting mail unchecked, and the application tries again later. Time is counted only while Postfix itself was running; ≈ marks a period with a start at which that could not be asked, and its time is at most what is shown. Counted since 2026-10-13.

Regenerates the Postfix configuration and the spam filter's lists from the database, removes the keys of deleted domains, and reloads Postfix. Use it after editing the files by hand, after restoring a backup, or when the running configuration looks out of step with the domain and application lists. It does not touch the queue or the TLS certificate.
