Speaking about gmail, I have no issues sending mail to all the differents free email providers,
maybe except that my host is listed in the spamhaus database so some hosts are offlimit
(higgs.linuxfromscratch.org among others).

I must say that linode is very popular wrt spam sendings and address collections which is
unfortunate.

That said, I did include all the major spam control measures such as spf and dkim (not shown below
but my dkim record do validate fine) and CAA ressources records except dmarc (this one's not ready
for prime time):

Rob, maybe it would help to have that set up and I can help in that regard.
