Hi Rob, No need to do another lookup in the router, just add a set acl_m_spf = 1 under your condition, then you can check for this in your router.

I'm using this: condition = ${if match{${lookup dnsdb{>\n; defer_never,txt=$domain}}}{\N(?m)^v=spf1\s\N} {1}{0}} The condition is working, if the domain has no TXT record then it does nothing to the sender address. The problem I am having is I am also adding a header to the router: headers_add = "X-SRS: Sender address rewritten from <$sender_address> to <${quote_local_part:${local_part:$address_data}}@${domain:$address_data}>" That header is being added to every message, even if the sender address was not altered. I thought it would only do that if the conditions(s) for the router were met but apparently not. So 2 questions: 1) Can I fix this easily with some command? 2) I think I can do it by wrapping a condition into the headers_add option (based on some searching), that option seems complex to figure out - but more importantly would the router do the DNS check two times? Once for the condition on the router itself and again to figure out if the headers_add would be added?
