I am planning to buy 4 SMTP servers using Digital Ocean as recommended by Hassan. But I have confusion about the setup of all 4 servers with MailWizz.
Like if I have to setup one server, I will use Putty and then Webmin to integrate MailWizz. This is for 1 SMTP server. What about multiple SMTP servers?? Do I need to create multiple webmin accounts for each server or I can setup all 4 SMTP servers on a single account of Webmin??
