Deliverability Checker

This one checks SPF, DKIM, DMARC, and MX records to figure out why your emails are hitting spam folders. You point it at a domain and get a scored audit with specific fixes, like the exact TXT record values you need to add. Built by ClawFu using dnspython, it's handy when setting up a new sending domain or debugging delivery issues after a migration. The command structure is clean, you can check individual records or run a full audit. Honestly most useful for folks who deal with email config regularly but don't want to manually dig through DNS every time something breaks.
