Hello Exist It, a way to send messages via multiple sending SMTP server. We will say yes, because I already paused the question in the forum. Why I rest it, simple, there is way to do it like Outlook or Gmail? I'm talking about the configuration in postfix or in ISPConfig, such as: [email protected] => smtp.domain.com [email protected] => smtp.domain2.com [email protected] => smtp.domain3.com Mz
