Vesta Control Panel - Forum

Hello,

I'd like to use IMAP and SMTP via SSL (and best case perfect forward secrecy, postfix should support that) - Does Vesta install any certificates for this by default and how can they be replaced?
I'd also need to setup the mailserver hostname, just edit postfix conf?

Hostname should be same as server fqdn hostname.

I don't have any responsibility for harm of your server and services...

Set server hostname:

# echo "server01.example.com" > /etc/hostname

Then edit and point your new hostname to servers public IP (don't remove 127.0.0.1 localhost, just edit second line):

# nano /etc/hosts
.
.
192.168.1.100 server01.example.com server01
.
.

Run SH:

# /etc/init.d/hostname.sh start

Now you should see:

# hostname
server01.example.com
# hostname -f
server01.example.com

Reboot may be required.
Exim4 takes hostname from system, but postfix must be configured (VestaCP has default MTA Exim4).
