Looks like this part does fix it (instructions for root server): [image: 1737492462373-9fbbe904-6e2e-4deb-8d7d-5d2812a54c83-image.png] Thanks to you both for the pointers!

Are there any mail gateway routers? So you can use different services with known good deliverability?

Yes I have DKIM setup. Thanks for the “relaxed” incantation. I’ll try that.

@RazielKanos said in can't send mails to gmail: The IP you're using to send mail is not authorized to send email directly to our servers. Please use the SMTP relay at your service provider instead.

See https://support.google.com/mail/answer/10336?hl=en . Basically, google does not like your IP. Maybe they have blocked the whole IP range of your VPS provider . You have to use a relay - https://docs.cloudron.io/email/#relay-outbound-mails

@girish Thanks for getting back. Yea I was able to sort this out. It appears it might have been related to the route I had established for internet traffic. Strange that it would only effect gmail, but this new route is simpler, and testing shows all mails being delivered without issue.

@girish Wow that worked perfectly, thank you so much!

@nebulon Thanks for helping me work through this!

@girish WHOOP!!! Thank you!!

@drpaneas said in gmail blocks my server?: @jdaviescoates I have cloudron installed at home. Ah, right.
