emails, Error 550 5.1.1.
« on: February 14, 2020, 10:32:13 AM »
Thank you all
I hope you understand what is written below.

And thanks for helping me I've been having problems with the server for 35 days.

With These Problems But Still, I find the best CWP Panel Host free ..
I have CWPpro ;-) I advise all this panel ..



I installed CWP on CentOs7 .. I put email on the System sistema@domiani.com. I changed Hostname to Server, When Receiving emails, Error 550 5.1.1. Create new email and it works well .. I went to see the error log, Name hostname is the old one, I ask it has nothing to do with the error?


log erro email

CWP There is no bug. I have little knowledge of Linux and CentOs ... This is the biggest bug ;-)

Thank you all

Running a server/VPS means YOU take responsibility to learn how to do it properly. If you can't manage, buy shared hosting.
Back to lurking mode. :-/

My guess:
/etc/postfix/main.cf

myhostname = (Your old hostname)

BUt just a guess.

If it's true, run the command
grep oldhostname *

to find all of the instances you need to change.
alternatively
sed -i "s@oldhostname@newhostname@g" /etc/postfix/*

OVH domain ..
Server Contabo .. Server-VPS Hostname  nameserv.mydomain.com

I think it is poorly configured at OVH.
It is like this..

Menu OVH configuration-> [Zona DNS]    [Server DNS]   [Forwarding]   [DynHost]     [ GLUE]     [Recent operations]

(configuration at OVH)-> Zona DNS

mydomain.com The IP
* .mydomain.com The IP
www.mydomain.com The IP

This configuration, Do not project the configuration emails?
I'm using free DNS
