I'm having a problem sending emails from my mail server to @gmail.com email addresses, because Google is complaining about me being 'unauthenticated', because the SPF check 'did not pass':

<<< 550-5.7.26 Your email has been blocked because the sender is unauthenticated. <<< 550-5.7.26 Gmail requires all senders to authenticate with either SPF or DKIM. <<< 550-5.7.26 <<< 550-5.7.26 Authentication results: <<< 550-5.7.26 DKIM = did not pass <<< 550-5.7.26 SPF [<my-domain-name>] with ip: [<my-ip-address>] = did not pass

(I've replaced my actual domain name and IP address with "<my-domain-name>" and "<my-ip-address>" here.)

Here's the SPF record in my server:

@ TXT "v=spf1 ip4:<my-ip-address> ~all"

(Again, I've replaced my actual IP address with "<my-ip-address>" here.)

I find that - while driving on the US-101 freeway - wireless Apple CarPlay frequently disconnects at some point between the Coyote Creek Golf Club exit, and the Cochrane Road exit. It seems that there is something in that area that is causing radio interference - enough to disrupt the wireless CarPlay connection between my iPhone and my car.

Is anyone else experiencing this?
