I have aaPanel installed on one of my VPS servers. I've been hosting via WHM and cPanel since the 00's, and Hestia CP for the past 18 mos or so. But
Mail can be tricky.
I select mail, and aaPanel recognizes that it's not installed. I proceed by clicking "Install" the mail server. Redis has been installed sucessfully, and password set in config. That's as far as I get.
Please let me know what you need to see, and where to find that log. Note: i suffered brain trauma a while ago, so forgive syntax errors and nonsensical rambling, please.
The VPS runs Ubuntu (latest). I have SSH and all that access of course. What do you recommend?
