…kenizer Replace the 10 separate regex patterns (each duplicating boundary lookaheads) with a keyword-based tokenizer aligned with RFC 5321 §4.4 grammar. Key improvements: - Tokenize on clause keywords (from/by/via/with/id/for) in a single pass instead of running 10 independent regex searches - Handle IBM "for <addr> from <sender>" by accepting only the first 'from' clause per header - Extract envelope-from/sender from parenthesized comments in clause values - Validate IPv4 octets (0-255) instead of matching any digits; add IPv6 support via REGXIP6 - Simplify JUNK_PATTERN to only collapse tabs/newlines, preserving parenthesized comments and bracketed IPs - Add 27-test corpus covering Postfix, Exim, Exchange, Gmail, SendGrid, IBM/Domino, AWS SES, and edge cases https://claude.ai/code/session_01CwmwWkvZGLpTBY6ApKFi79
