I'm having problems sending bulk mail to gmail. According to this I have to: Sign messages with DKIM. We do not authenticate messages signed with keys using fewer than 1024 bits. Publish an SPF record. Publish a DMARC policy. I already have SPF record and DKIM and now I'm trying with DMARC. I have this record: TYPE NAME CONTENT TXT _dmarc.igorgarcia.es v=DMARC1; p=none I dont know if it's OK. I tested it on unlocktheinbox but ir always said there are No records to display. Another way to test my DMARC records?
