unable to send email to a Gmail address

[stefanwirtz]

I hope there is an easy & not too technical solution to this issue... if it gets too technical & complicated I will have to resort to hosting my email elsewhere

Gmail is sensitive to SPAM and does many checks on the connecting mail server.

As the message says there is a problem with your PTR from their perspective.

Make sure to check IPv4 and IPv6 PTR as they check both.

If you just setup the domain, server, and cloudron please note DNS and PTR can take up to 48 hours to take full effect.

[stefanwirtz]

thank you for your input, I am double checking IPV4&6 with my VPS provider right now

[stefanwirtz]

My VPS provider indicated the IPV6 address is missing on Cloudflare. I have now added the AAAA record at both root and mail level and am now giving it some time to propagate before trying to send the email to gmail again. Further I am deleting the temporary smtp server Mailersend. Hopefully this solves the problem and will inform you later how it went. Thank you

[stefanwirtz]

Update: I am now able to send emails WITHOUT receiving an immediate error message, however, the email is not arriving in the recipient's email inbox or spam..any ideas?

[stefanwirtz]

Ah, I just realized that on Cloudron, for the domain in question, I had to switch from external smtp back to built-in smtp...let's see if this does the trick...can you tell I am a non-techie??

[stefanwirtz]

...and BINGO, I can now send email to Gmail...message was received in the INBOX. We can now close this ticket. Thank you for your help and I am so glad I can keep email hosted on Cloudron.

We had that issue and decided that we simply wouldn't reply to anyone contacting us from a gmail address

They clearly have no interest in freedom, and we don't want our comms being indexed on google servers.

Heh, that's a pretty hardcore approach to take... but also probably not that effective imho given how many people use Google Workspace and there don't have gmail addresses but are still using Google.

To do it properly you'd need to block anything coming from any Google owned IP address.

[nostrdev]

True. In the meantime, we tell anyone and everyone about how and why they should move to Cloudron.

@nostrdev So glad you listened when we chatted about that too!

Welcome.
