Multiple domain email

Posted April 6, 2018 1.8k views

Hello good afternoon
I moved all my websites from a shared host to a DO’s droplet. I installed VestaCP to manage everything. For about a week emails worked fine… But yesterday starts an error… All emails sent, is being delivered as spam (Google) or not being delivered (domains hosted on another hosting)… If I send a email to another domain that is on the same droplet i receive the message…

The result of the comand sudo tail /var/log/exim4/mainlog returns this
2018-04-06 16:08:42 1f4Tuq-0001uR-GN 1.2.34]: SMTP error from remote mail server after RCPT 450 4.7.25 Client host rejected: cannot find your hostname, []

My configs…

Digital Ocean droplet: name ->
DigitalOceans Domains: All domains hosted on the droplet
Digital Ocean DNS: All domains have 3 ns entries, and one more A @ pointing to droplet IP
VestaCP: using basic VESTACP domain’s DNS

Anyone can help me?

I don’t know if the DNS didn’t propagate…

what i’ve done..
Added the A DNS to all domains hosted on Droplet
Rename the droplet to name of main domain hosted on droplet
