Mail Attachments — Find Emails with Files

Search: $ARGUMENTS

Step 1: Search attachment filenames in the index

DB="$HOME/Library/Mail/V10/MailData/Envelope Index"
TERM="<extracted from $ARGUMENTS, or % for all>"

sqlite3 "$DB" "
SELECT datetime(m.date_received,'unixepoch','localtime') as dt,
       s.subject, a.address as sender, a.comment as name,
       att.name as filename, mb.url as mailbox, m.ROWID, m.size
FROM messages m
JOIN subjects    s   ON m.subject   = s.ROWID
JOIN addresses   a   ON m.sender    = a.ROWID
JOIN mailboxes   mb  ON m.mailbox   = mb.ROWID
JOIN attachments att ON att.message = m.ROWID
WHERE att.name LIKE '%TERM%'
  AND m.deleted = 0
  AND mb.url NOT LIKE '%Spam%'
  AND mb.url NOT LIKE '%Trash%'
ORDER BY m.date_received DESC
LIMIT 50;" 2>/dev/null

Step 2: Filter by extension

For specific types, add to WHERE:

PDF: AND (att.name LIKE '%.pdf' OR att.name LIKE '%.PDF')
Spreadsheet: AND (att.name LIKE '%.xlsx' OR att.name LIKE '%.csv' OR att.name LIKE '%.xls')
Image: AND (att.name LIKE '%.png' OR att.name LIKE '%.jpg' OR att.name LIKE '%.jpeg')
Document: AND (att.name LIKE '%.doc%' OR att.name LIKE '%.pdf')

Step 3: Filter by size (large attachments)

AND m.size > 1000000   -- messages > ~1MB

Step 4: Get all attachments on a specific message

sqlite3 "$DB" "
SELECT att.name, m.size
FROM attachments att
JOIN messages m ON att.message = m.ROWID
WHERE m.ROWID = <ROWID>;" 2>/dev/null

Step 5: Find the actual file on disk

Attachment files are stored alongside their .emlx:

# Find the emlx first
EMLX=$(find ~/Library/Mail/V10/ -name "<ROWID>.emlx" 2>/dev/null | head -1)
# Attachments are in the same directory or in an Attachments subfolder
EMLX_DIR=$(dirname "$EMLX")
ls "$EMLX_DIR"
find "$EMLX_DIR" -not -name "*.emlx" -not -name "*.plist" 2>/dev/null

Output Format

Show as table:

Date	Sender	Subject	Filename	Size

Group by file type if searching broadly. Note the email ROWID so user can request to read the message. If attachment files are locally cached, show their path.
