Every mail.log line headed by a queue id is written to send_log_lines as the tailer reads it, dated by the line's own stamp. The id is taken from the head of the line only - the tail is the far end's text - and has to look like one: "NOQUEUE:" and "warning:" stand in the same place. The tailer does not check for a send-log row first: a message's first lines come before the journal milter writes it. Lines that never get a row are removed by the prune, which deletes lines older than an hour whose queue id no row carries. It runs at start, after each send-log sweep and hourly. While the tailer catches up at start a line is written only if it is not there already, as the inbound journal does: its place is saved every few seconds, so an unclean stop means reading some lines twice. Checked on Windows: go vet clean; go test ./internal/logtail passes except TestFollowTailsAndRotates, which fails there on renaming an open file and always did. New tests: which line heads are queue ids, a line dated by its stamp, no second copy after a rewound offset, the prune cadence and cutoff. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
