So I installed Virtualmin months ago. I just did the basic setup and was able to setup everything fine. The other day I tried to setup thunderbird to receive and send mail. I am able to receive mail no problem but sending will not work.
Now I’ve tried doing a little research, and see things talking about postfix setup, sendmail, dovecot. Just seems like there is more ways for me to screw this up.
So basically im looking for the easiest way to setup the outgoing email from clients(thunderbird, mobile phones, etc).
I do see the below in my maillog
