INFORMATION Virtualmin 4.01 Pro Operating system = CentOS Linux 6.4 x64 Postfix version = 2.6.6 Dovecot version = 2.0.9
I am trying to figure out and understand a lot more about how Postfix and dovecot work still and what a lot of the options in virtualmin mean and do. But I'm stuck.
I want to have some sort of security on SMTP instead of just plaintext, SSL/TLS would be nice. I have a wildcard certificate for my domain as well.
Can anyone help me out here? I'm really interested in learning more in unix and all these services and how things work.
I've attached a screen shot of Thunderbird auto configure attempt, the settings listed in the screenshot are the same ones my iPhone uses (It tells me can't connect with SSL for SMTP).
Any advice would be greatly appreciated. Thanks in advanced.
