Re: Zimbra 8.8.15 patch23 LDAP segmentation fault

DKIM and OWASP HTML Sanitizer...

I've got a funny case where an incoming email has the following in the headers (sanitized a bit): Authentication-Results: mail.abcxyz.com (amavisd-new); dkim=fail (1024-bit key) reason="fail (body has been altered)" header.d=amajorusbank.com which I think fires off the hit on DMARC_FAIL_RE...
