1) Install Centos 6-64 with hostname your-site.com on your server
3) Setup DNS records for your-site.com
4) Install Vesta on your server with default params and hostname=your-site.com
5) Check if your-site.com is working (can be opened in you browser)
6) Create mailboxes via vesta cp like sender@your-site.com bounce@your-site.com
7) Add mail servers to mailwizz
8) Validate and get Profit!

on a number of control panels you run into serious trouble later if you do not set the hostname properly as a FQDN (three parts, two dots: www.domain.com or mwz.domain.net or host1.domain.org)

IMPORTANT UPDATES:

I just tried sendgrid SMTP and it works on both modes swiftmailer and phpmailer, it seems like the problem is on the server where powermta is installed.

DO YOU HAVE ANYIDEA what is the issue ?

Best,

pls
first switch on debug
then run sending in cli verbose mode (and capture in log)
then post (or PM) error/send logs of app, server, pmta, etc (anything else involved)
