Help me…

Now I’m successfully running mail server. I’m follow this tutorial

But I’m not happy with the servername, because this is not my main domain.

Is it possible to change servername..? example if we already setup mail server with imap : mail.somedomain.com and change to mail.otherdomain.com..?

Please help me..

Thank you..

Yes, it is possible to change the name, first rename your droplet, then inside your droplet modify /etc/hostname and restart network or restart your droplet.

As I don’t know what OS Distro are you using this procedure can change, so be sure to google hot to rename hostname on your distro,

Thank you for your answer,
I use ubuntu Ubuntu 14.04,

Now, my email client (thunderbird) only can connect with my mail server with this setting

Incoming Imap
Servername: mail.mydomain.com
Port: 993
SSL: SSL/TLS
Authentication: Normal Password

Outgoing SMTP:
Servername: mydomain.com
Port: 587
Authentication: Normal Password

What I want change servername for Incoming IMAP and Outgoing SMTP. I want to change to other domain.
