The latest German magazine Mac & i has a nice review on Mail Archiver X.
Because the magazine is paid I can't show the review here. Here is a summary:
- Archiving & Storage: Saves emails locally in formats like MBOX, PDFs, or a Valentina-based database, freeing up server space.
- Compatibility: Works with Apple Mail, Outlook, Thunderbird, and IMAP accounts.
- Selective Archiving: Filters by date, age, or folder, excluding duplicates.
- Automation: Supports scheduled archiving with reports.
- Search & Backup: Offers robust search tools and export options, with the ability to re-upload to IMAP.
Efficient and easy to use, it processes large mailboxes quickly and is ideal for safeguarding emails.
