and here is my msmtp config ( I just copy from cuttlefish app page , and only update the host ip address )

account cuttlefish
tls on
tls_trust_file /etc/ssl/certs/ca-certificates.crt
host 192.168.11.13
port 2525
auth on
user acting_twins_2
password iuVdHL7totip5g7MN5Ge
from cuttlefish
tls_certcheck off
account default : cuttlefish

any suggestions ??

update msmtp debug info
