When NeoMutt starts up it looks for two configuration files – one “ system” file and one “ user” file.
NeoMutt first reads the system configuration file, then the user configuration file. The two files are merged in the sense that "last setting wins". That is, if a setting is defined in both files, the user configuration file's value for that setting is the one that takes precedence and becomes effective.
NeoMutt searches for several different file names when looking for config. It looks for NeoMutt config files before Mutt config files and versioned config before plain config.

FairEmail is easy to setup and works with virtually all email providers, including Gmail, Outlook and Yahoo!
FairEmail might be for you if you value your privacy.
FairEmail does not support non-standard protocols, like Microsoft Exchange Web Services and Microsoft ActiveSync.
This site lets you create a muttrc configuration file for the Mutt email program. You specify your preferences in the boxes on the next few pages, and you get a muttrc you can use.
None of the data you enter is stored permanently, but as the Internet is not secure, you should not enter any sensitive information such as passwords. Enter a placeholder instead (such as "password goes here" and replace it in the file you download.
The idea is based on netliberte's sadly-defunct muttrc builder.
