Hello, I have 8 emails under the same domain name. One is the main email that I use, and the other 7 are using other colleagues. But recently, I found out that no matter which email I choose to send the emails, all the emails are sending out with my main email. Just an example: my main email is [email protected], and the other one are [email protected], [email protected], etc., but every time I write an email using the [email protected] account, the email are sending out as [email protected]. I even tried to send a test email using the [email protected] account and sent to [email protected], and in my inbox, I received an email from [email protected] to [email protected] Why is that? Can anyone help me, please? Thanks!
