Good day. I'm new with vesta, I found it very amazing for some videos that I sawon youtube. I decided to install it on my google cloud instance. I created my own nameservers, so they're managed from vesta and updated as hostnames and nameservers in my domain registrar.
I did some research to make work some parts that was failing, one of them roundcube webmail. When I finally got the roundcube working I test it sending a mail to my personal account, I waited 20 minutos and nothing about it in the inbox.
So I started to search about it and I found this tool https://mxtoolbox.com/ and with that, detected 2 problems
1. The lack of a decent dmarc TXT record
So I added it to my domain
2. "Reverse DNS does not match SMTP Banner"
For that I added the right line to the exim4 config
and found this information https://serverfault.com/questions/77960 ... ute/815598 , so I followed the steps on my instance.
Tested again, but it's still failing it. Please help I'm very confused at this point what else could be?

Google cloud blocks outgoing port 25 by default and as far as I know they will not open it for you, your only choice is to use a third party service like sendgrid or mailgun, or even switch to a VPS provider and then ask them to open port 25 (they will also block by default but are more willing to open if asked)
Hope this helps.
