check-email-caps

Find contacts with uppercase letters in their email addresses.

Email addresses are case-insensitive in practice, so Mark@Gmail.com should be mark@gmail.com.

Usage

rscontacts check-email-caps
rscontacts check-email-caps --fix
rscontacts check-email-caps --fix --dry-run

Fix Behavior

With --fix, automatically lowercases all email addresses for each affected contact. No interactive prompt since the fix is unambiguous.
