I am a server administrator and want to be able to read emails (stored by EXIM in the "Maildir" format) in various accounts in a convenient, email client manner, without needing to enter a password. This would be done from a root command line. From what I have seen, "Mutt" will be able to access the various emails stored in the Maildir format, but I am unsure if I will need a password for each email account. I do not want to install Mutt on the server only to find out I will need the password for each account.
Since I did not get any prompt responses, I went ahead and installed Mutt on my server. Indeed, as root I can access all the various mail accounts on the server without needing any passwords. Since most published information about Mutt addresses single, non root account access, they show a password being needed. In my circumstances, a password is not required. This allows me to assist my clients, and perform various email account housecleaning tasks easier than other ways which do not have any GUI.
