mailcap Module¶
⚠️ REMOVED IN PYTHON 3.13: The mailcap module was deprecated in Python 3.11 and removed in Python 3.13.
The mailcap module reads mailcap files, which define how MIME types should be handled by external applications.
Complexity Reference¶
| Operation | Time | Space | Notes |
|---|---|---|---|
init() |
O(n) | O(n) | n = mailcap entries |

O(1) | O(1) | Hash lookup |
Reading Mailcap Database¶
Getting MIME Handlers¶
import mailcap
# Initialize - O(n)
caps = mailcap.getcaps()
# Find handler - O(1)
handler, copiousoutput = mailcap.findmatch(
caps,
'image/png',
'view'
)
print(handler) # e.g., 'eog %s'
# Find with fallback
match = mailcap.findmatch(caps, 'text/html', 'view')
if match[0]:
print(f"Handler: {match[0]}")
