Hello,
So I’ve installed virtualmin on Ubuntu 16.04, and when I try to connect to send an email from roundcube or thunderbird, it says authentication failed.
I’ve fixed it with this: https://nfolamp.wordpress.com/2013/02/04/fixing-postfix-and-saslauthd-cannot-connect-to-saslauthd/
But am I the only one to have this problem? Is there a way to fix it while installing virtualmin?
