Thunderbird 52.4.0 / Lightning 5.4.4

When sending an invitation to any @gmail.com users, the email gets bounced back by Google with these details:

550-5.7.1 Unauthenticated email from domain.com is not accepted due to 550-5.7.1 domain's DMARC policy. Please contact the administrator of 550-5.7.1 domain.com domain if this was a legitimate mail. Please visit 550-5.7.1 https://support.google.com/mail/answer/2451690 to learn about the 550 5.7.1 DMARC initiative.

This is my current SPF DMARC Entry: v=DMARC1; p=reject; sp=none; adkim=s; aspf=s; rf=afrf; pct=100; ri=86400

This is my SPF Record: v=spf1 mx a ip4:111.222.333.444/32 include:myofficedomain.net include:_spf.google.com ~all

Any clue? Thanks!

Seems outgoing invitation emails are not authenticated.

I am wondering which SMTP server mail is sent from. Is there a configuration for this?

Thanks all for your support.

How many googlemail accounts do you have? Each should be using its own unique smtp set-up under Edit|Account Settings|Outgoing Server (SMTP) and selected in the corresponding incoming account.
