What’s New
Read the latest changes in the Changelog.
Smart De‑Duplication
Respects existing attachments and avoids duplicates by filename, clean and predictable.
Skip SMIME & Inline
SMIME signatures are never copied. Images embedded in the message body stay in the reply body, where Thunderbird keeps them, rather than being attached a second time.
Blacklist Patterns
Case‑insensitive glob patterns like *.png or smime.* prevent adding noisy files.
