Hi, recently started using ISPConfig3, I have a question regarding relayhost. Is it passed over 25/465/587? Is it possible to configure it to a specifc protocol?
By default, postfix uses port 25. if you want to use a different port, then you can set the port by specifying it with servernameortnumber. Example: mx.yourdomain.tld:587
So I can relay to mailgun with encryption by entering smtp.mailgun.org:587 in the relayhost server field? Do I need tls:// or something?
