aerc implements the maildir format.
Maildir accounts currently are not supported with the :new-account command and must be added manually to the aerc-config(5) file.
The following maildir-specific options are available:
The source indicates the path to the directory containing your maildirs rather than one maildir specifically.
The path portion of the URL following maildir:// must be either an absolute path prefixed by / or a path relative to your home directory prefixed with ~. For example:
source = maildir:///home/me/mail
source = maildir://~/mail
