I'm doing a migration for my client for his website based on WordPress - from hosting to VPS. I am using apache2 for WordPress. I changed the DNS to the new IP (VPS) in the DNS control panel and WordPress is working good.
Now I want to configure e-mail on this server with panel to login to inbox etc. I am using this tutorial.
I installed postfix, devocot and roundcube. I created a user and I can send emails from the terminal with:
sendmail <delivery_email_address>
and these mails are received by my Gmail account.
But when I send email from my Gmail account to the same e-mail (VPS), I don't have anything. Roundcube is empty. I also checked /var/mail/info (info is the user), but also empty.
How can I troubleshoot this? What is not working properly here?
Additionally, I received emails from 'info@mail.mydomain.com', but my hostname variable in Ubuntu is 'domain.com' ('domain.com' is just an example). Is this a problem? Why?
Where I should search for the incoming mails? I guess Roundcube is loading mails from a specific file, and this file is empty, so is the inbox too?
General:
postfix,dovecotservices running- Ubuntu 21.04
- Roundcube 1.4.8-complete
