Domain's email account with phpMailer and Gmail

问题

Two scenarios:

1. I recently downloaded the phpMailer and added it to my public_html folder.
2. I add my domain's email accounts to my gmail account.

Two problems:

• When sending emails (domain's email account) using phpMailer and Gmail, and when the recipient received it, the red question mark is appearing instead of the Gmail's default profile photo.

What do I need to do to solve this? I searched about in phpMailer that I need some DKIM and SPF keys or something.

回答1:

Your message is not authenticated, you must set a SPF configuration this is a TXT record on your domain (envelope). For Example "v=spf1 ip4:204.200.197.197 -all" means the ip 204.200.197.197 is allowed to send mails over your domain.
