We use a third-party listserv to send email to our memebers. Some of them bounce because of improper SPF DNS entry.
This is what we have currently:
v=spf1 a mx include:onedomain.net include:anotherdomain.com -all
The " include:onedomain.net include:anotherdomain.com" are for other domains we send email from.
The server that the emails in question come from is listserv.ourdomain.org.
Do I need our new SPF record to look like:
v=spf1 a:listserv.ourdomain.org include:onedomain.com include:anotherdomain.net ~all
