Bill, the following is what I wrote to ZoneEdit support:
"I use ZoneEdit for DNS hosting for the domain foo.net. When I send email messages to a Gmail address, Gmail discards (does not deliver) my email messages that have the return address <abc@foo.net>. Gmail apparently thinks that messages with that return address are spam and apparently requires DKIM on those email messages for it to deliver the messages.
"Can ZoneEdit add the proper DKIM (and SPF) information to my email messages with the return address <abc@foo.net>? That is, can ZoneEdit show that I have the authority to send messages with that return address?"
Here is the reply from ZoneEdit support:
"I would recommend looking up what information is required for the SPF and DKIM record via Google. You can then add the proper DKIM / SPF record as per whatever Gmail instructs. The SPF/DKIM record will be put into the TXT Record section in your Zoneedit DNS Settings page."
My question to you, Bill, is, "Where in Google (Gmail) would I find the DKIM/SPF information I would need to put on my ZoneEdit settings page?"
Thank you.
