I've some questions: Our situation here is, that we host mailservices for several customers. We have also our own DNS servers and so we're able to set up SPF TXT records. But as I understand we can't set up silently this records for all our domains because we can't be sure that all of our clients send all their outgoing (legit) mail traffic trough our Mailserver. (that we've authorized in the SPF records) For example if there is on customer side an Exchange Admin that has set up his server to make MX lookups and route outgoing SMTP traffic directly to the recipients server. I know it's risky to do this from a dynamic IP or without REVDNS-entry ..., but this is not under our control. So as I can understand we have to parse trough our smtp-logfiles to find out which customer send his outgoing mail trough our server. Then we can add SPF records only for this domains. Otherwise we risk to penalize our customers outgoing mail traffic if it's not send trough our server and the destination makes also SPF lookups. Right or do I miss something?
