Hi.
You add DKIM + SPF for you domain?

Are you sure you can't send email to gmail? I thought the same thing. I set up email in Vesta and sent test emails to another of my self-hosted email accounts, my gmail account and my hotmail account. I didn't receive the test emails to gmail or hotmail - or so I thought. After more thought, I checked my spam/trash and the emails were being marked as spam, so they weren't getting to the inbox of those accounts. Once I marked them as "not spam", I started receiving the emails in the inbox.

Same there(only for gmail servers)
H=gmail-smtp-in.l.google.com [108.177.126.27] TLS error on connection (recv): Resource temporarily unavailable, try again.

The server hostname must be valid, have an SSL Certificate in good condition and be configured in configurations from the VestaCP Admin. On the other hand you must ensure that the domain has the MX correctly configured towards the VestaCP and not in G Suite (if you have G Suite)

Hi. Thanks for your answer
The spam score (mail-tester.com ) is 10/10
So the problem is something else(((

I have lxc ubuntu 18.04... So I think it's a bug

Gmail distrusts by default the emails sent from unknown IPs and classifies them as spam.

The fastest way to solve this is to ask Gmail users to send you a new email. From that moment, those users will receive your emails in their inbox. Over time, Gmail will trust your IP and distribute your email to any account, as long as no abusive use is made.
