mail_dns_check 0.0.2

Check a domain's email DNS records: SPF, DMARC, DKIM, and MX, with stable issue codes for missing, duplicate, and risky settings. Pure Dart.

0.0.2

• Fix SPF lookup counting following redirect in a record that also has an all mechanism. RFC 7208 ignores the redirect in that case.
• Report spf_too_many_void_lookups when more than two include or redirect targets return no records, and add MailDnsReport.spfVoidLookups.
• Add pub.dev and CI badges to the README.

0.0.1

• Initial release.
• MailDnsChecker.check inspects MX, SPF, DMARC, and DKIM records over DNS-over-HTTPS and returns a MailDnsReport with stable issue codes.
• SPF lookups are counted through includes and redirects against the RFC 7208 limit of 10.
• SpfRecord, DmarcRecord, DkimRecord, and MxRecord parse record text without any network.
