send email by instead of

Hello everyone, I’m Daniel

I use virtuamin for years and I have a new problem that I never happened before.

In practice, when I send the email from the server to the recipient that the email I sent to instead of

This creates many problems because they can not answer.

I using Virtualmin 4.12 postfix 2.6.6 and dovecot 2.0.9 on centos 6

Do you know how can I fix it?

Thanks in advance



What are you using to send the email? Is that being sent from a website? Or is that being send from a mail client such as Outlook or Thunderbird?
