AuthenticationResultsHeader

✓ from authres import AuthenticationResultsHeader

Always use this import; no common wrong alternative.

Parse and generate Authentication-Results headers.

from authres import AuthenticationResultsHeader # Parse an Authentication-Results header header = 'dmarc=pass header.from=example.com; spf=pass smtp.mailfrom=email@example.com' parsed = AuthenticationResultsHeader.parse(header) print(parsed.results) # Generate a new header from authres import AuthenticationResultsHeader, AuthResult result = AuthResult('dmarc', 'pass', {'header.from': 'example.com'}) header_obj = AuthenticationResultsHeader('mail.example.com', [result]) print(str(header_obj))

Debug

Known issues

gotchaThe library only supports RFC 8601, not earlier drafts. Headers using 'smtp.mailfrom' (with dot) vs 'smtp.mailfrom' (underscore) may cause parsing issues.

fix

Ensure your header strings use RFC 8601 format exactly.

affects: 1.0.0 - 1.2.0

gotchaParsing multiple header lines requires concatenating them with newlines; passing them as separate arguments is not supported.

fix

Supply the entire header value as a single string, with newlines separating lines if multi-line.

affects: all

deprecatedThe library is no longer actively maintained; no updates since 2021. It may not work with future Python versions.

fix

Consider alternatives or pin Python version (tested up to 3.10).

affects: all

Errors

Common errors & fixes

AttributeError: module 'authres' has no attribute 'AuthenticationResultsHeader'

The import path is correct but some installations may have a different version or package name collision.

fix

Run 'pip install --upgrade authres' to ensure version 1.2.0 installed.

TypeError: AuthenticationResultsHeader.parse() takes 1 positional argument but 2 were given

Trying to pass additional parameters like instance method incorrectly.

fix

Use AuthenticationResultsHeader.parse(header_string) without extra arguments.

ValueError: Invalid header format

Header string does not conform to RFC 8601 syntax, e.g., missing '=' in key-value pairs.

fix

Ensure header format: 'method=result key=value' with spaces separating key-value pairs.
