It gives a link to this guide: https://support.google.com/mail/answer/8...entication

But it unfortunately doesn't say exactly what's causing it.

Yes, this is a known flaw in GMail. It's why the iPXE contact page now explicitly states that GMail (and only GMail) addresses are not supported.

Unfortunately, GMail seems to be totally uninterested in fixing their problem, so all we can do is require that people use another mail provider if they want to get reliable delivery of messages.

From one forum mail:
Code:
Authentication-Results: mx.google.com;
       spf=fail (google.com: domain of apache@fensystems.co.uk does not designate 2001:ba8:0:1d4:e4c4:daff:fece:219b as permitted sender) smtp.mail=apache@fensystems.co.uk
Received: by duck.fensystems.co.uk (Postfix, from userid 73)

the spf record only allows the mx: "v=spf1 mx -all"

The mx aaaa does not point to the IPv6 address that the mail is sent from.
duck.fensystems.co.uk. 600 IN AAAA 2001:ba8:0:1d4::6950:5845

So by SPF I would say that gmail does the right thing.
