Action Log.
Mail Shepherd 3.0 for the Mac App Store (build 535) · Updated October 24, 2026
The Action Log lists what Mail Shepherd did, newest first (the latest 500 entries): each message a Sweep, an Auto-Sweep or a Review page changed, each change to your lists, and every problem. Each row shows the date and time, the action, the sender, the subject and the details. Before each delete, the message is written to the log, so even an interrupted delete leaves a record.
- The menu shows All entries or Problems Only: problems, changes the server didn’t confirm (“Unconfirmed”), and stopped Sweeps.
- The search box shows the entries whose action, sender, subject or details contain what you type.
- Click a row to see all of its fields in full, including the mailbox, when the message was sent and received, and its message UID. ↑ and ↓ go to the entry above or below (“3 of 500”). Copy copies every field, for example to send to support; Done (Esc) goes back to the list.
- Open Text File opens this week’s log file, and Show in Finder shows the log folder. The history is kept in weekly files on this Mac for 4 weeks; the Auto-Sweep history and monthly Sweep statistics are kept beside it.
- Clear Log asks first, then moves the log and its weekly files to the Trash, where you can still restore them, and starts an empty log.
The Action Log lists changes one by one. For each Sweep’s step-by-step log, see Sweep Logs in the sidebar.
Warning icons
Mail Shepherd doesn’t show alerts or completion messages. When something you did, or an Auto-Sweep, runs into a problem, the problem is added to the Action Log and the page shows an orange warning icon, for example beside Sweep or in a Review page’s footer. Point at it to read the problem; click it to open the Action Log.
Crash reports
If Mail Shepherd crashes, macOS gives it a crash report, usually the next time it opens. The report is added to the Action Log as “Problem: Mail Shepherd crashed”. Nothing is sent anywhere; if you write to support, you can copy the entry into your message.
