I'm basically ready to give up and move to a paid email provider so that they can deal with getting emails delivered to @Google@twitter.com.
Thanks Google, thanks for working to kill XMPP, RSS and Email.
Thank you, you self-serving, hypocritical, creepy data-guzzling, pretentious fucks.
@Google@twitter.com Update on my struggle to get my emails delivered to Gmail.
Based on a tip from @ij, I've configured Postfix to use IPv4 when sending to Gmail.
Since then I've successfully sent two emails to Gmail addresses.
Fingers crossed that this fixes it for good.
@jcbrand I'm curious why Google is bouncing your emails. I've had a slightly similar problem months ago for one of the servers of my work. No more bouncing after adding SPF and DMARC records, and checking them.
Thanks, all that's been checked and is OK.
@jcbrand - are you delivering it via IPv6? Usually I‘ve less problems by just delivering via IPv4 to Google.
Another thought of mine would be to just refuse accepting incoming mails because of their broken mail setup of Google.
I don't have IPv6 disabled, so I think it's definitely possible that it's being used. Will double check.
@jcbrand - you don't need to disable IPv6 at all... in my mailserver setup I've added a domain list for ipv4_only and a matching router/transport for it... If you're using Postfix, I'm sure it should be possible to do something similar there...
I've configured postfix to use IPv4 for Gmail.
So far so good, two emails have been sent out successfully.
Hopefully it continues to work.
Thanks for the tip!
@jcbrand - you're welcome!
Be aware that there are other domains that are using Gmail servers, so you might need to adapt the list of hosts/domains. Sadly I've found no setting in Exim that tells it to use the MX records a criteria for ipv4 or not. Maybe Postfix has something...
But in the end, Googles mailserver are broken in some regard and it doesn't mean that IPv4 will always work like that. Avoiding/refusing Gmail at all is the only sane way, I think...
@ij yes I already added other domains that use Google.
Unfortunately refusing to communicate with people who use Gmail isn't a realistic option.
