I would like to use Gmail to send email from another email address such as [email protected] so that the email sender will appear as [email protected] when people receive my emails.
I found the following intructions for achieving this:
Send mail from a different address or alias
But there is one thing that I don't understand, it does not mention anything about setting up the SPF(Sender Policy Framework) record. If I don't change the SPF record to explicitly allow google email servers to send emails on behalf of mydomain.com, will it still work and is this reliable? And why doesn't google mention about this?
