Please try to set either SMTP authenticator and/or IMAP authenticator:

# set imap_authenticators=""
#
# Name: imap_authenticators
# Type: string
# Default: ""
# 
# 
# This is a colon-delimited list of authentication methods mutt may
# attempt to use to log in to an IMAP server, in the order mutt should
# try them.  Authentication methods are either ``login'' or the right
# side of an IMAP ``AUTH=xxx'' capability string, e.g. ``digest-md5'', ``gssapi''
# or ``cram-md5''. This option is case-insensitive. If it's
# unset (the default) mutt will try all available methods,
# in order from most-secure to least-secure.
# 
# Example:
# set imap_authenticators="gssapi:cram-md5:login"
# 
# Note: Mutt will only fall back to other authentication methods if
# the previous methods are unavailable. If a method is available but
# authentication fails, mutt will not connect to the IMAP server.
