Dear, I have a Postfix server and I have SPF and DKIM TXT records in my DNS. Everything works OK. But now I want to implement DMARC, but somebody tells me not to do it because I'd have some problems and I'll have to use a whitelist for several emai addresses, and it's a heavy additional work. Please can you tell me your opinion about DMARC usage ??? Thanks a lot. I implemented DMARC recently because of problems with City officials emails being used for fraud. I get the reports, I know that people in other countries are using our email addresses, I have not the faintest idea what I can do about it. I am having trouble understanding the purpose of the reports I receive, I can't do anything with the information. And this digresses into a DMARC discussion, not a Postfix discussion. DAve
