freebsd-questions:

I have a SOHO network with a FreeBSD computer:

2022-05-07 22:28:10 toor@f3 ~
# freebsd-version ; uname -a
12.3-RELEASE-p5
FreeBSD f3.tracy.holgerdanske.com 12.3-RELEASE-p5 FreeBSD 
12.3-RELEASE-p5 GENERIC  amd64


I would like to read mail for the root account on the above computer by 
using an e-mail client, IMAP, and TLS (Thunderbird) on another LAN computer.


How do I accomplish this goal?  Are there any tutorials available on the 
WWW?


TIA,

David
