Hi, I just update my Centos 9, I follow the steps

# chown vmail:dovecot /var/log/dovecot.log
# chmod 660 /var/log/dovecot.log

But in the /var/log/maillog, I got an error.

Error: net_connect_unix(/run/dovecot/stats-writer) failed: Permission))

I do see /var/log/dovecot.log with no issue. I still can send & receive emails though. What is the cause on this? Many thanks and great instructions!

In reply to Frank. @Frank, You must set your domain under "myhostname" in /etc/postfix/main.cf file.

myhostname = mydomain.com

Not getting any answer?

Here is the raw header from Gmail

Received: by T320.localdomain (Postfix, from userid 1000) id 90B1920813085; Wed,

I wish it is

Received: by mydomain.com (Postfix, from userid 1000) id 90B1920813085; Wed,

Hi,

Thank you for your great tutorial! There is one issue though.

I can now send email using thunderbird to my Gmail account and Gmail actually receives it. However, I look at the raw header from Gmail. It shows

Received: from T320.localdomain ([my-ip-address]).

Where T320 is my Linux hostname. How can I make it show the actual domain, such as mydomain.com, as below:

Received: from mydomain.com ([my-ip-address]).

My machine has two domains pointing to it with same ip address….

Password mismatch? Check my comment in the first part of this article.

I will quote it here:

After hours and hours just found the issue…

`password` VARCHAR(100) NOT NULL,

But the result of

ENCRYPT(‘PasswordForFirstEmailAccount’, CONCAT(‘$6$’, SUBSTRING(SHA(RAND()), -16)))

will always exceed 100 characters
