# This file focusses on TLS and authentication. Features not used here include

# logging, timeouts, SOCKS proxies, TLS parameters, Delivery Status Notification

# (DSN) settings, and more.

# Set default values for all following accounts.

defaults

logfile /root/msmtp.log

# Use the mail submission port 587 instead of the SMTP port 25.

#port 587

# Always use TLS.

#tls on

# Set a list of trusted CAs for TLS. You can use a system-wide default file,

# as in this example, or download the root certificate of your CA and use that.

#tls_trust_file /etc/ssl/certs/ca-certificates.crt

# Additionally, you should use the tls_crl_file command to check for revoked

# certificates, but unfortunately getting revocation lists and keeping them

# up to date is not straightforward.

#tls_crl_file ~/.tls-crls

# A freemail service

account report

# Host name of the SMTP server

# As an alternative to tls_trust_file/tls_crl_file, you can use tls_fingerprint

# to pin a single certificate. You have to update the fingerprint when the

# server certificate changes, but an attacker cannot trick you into accepting

# a fraudulent certificate. Get the fingerprint with

# $ msmtp --serverinfo --tls --tls-certcheck=off --host=smtp.freemail.example

#tls_fingerprint 00:11:22:33:44:55:66:77:88:99:AA:BB:CC:DD:EE:FF:00:11:22:33

# Envelope-from address

# Authentication. The password is given using one of five methods, see below.

host smtp.5ikuma.com

domain 5ikuma.com

from report@5ikuma.com       

auth login

#这里auth要指定方式，如果用ON的话，会报错。我这里直接使用login的方式

user report@5ikuma.com

password *******

# Password method 1: Add the password to the system keyring, and let msmtp get

# it automatically. To set the keyring password using Gnome‘s libsecret:

# $ secret-tool store --label=msmtp \

#   host smtp.freemail.example \

#   service smtp \

#   user joe.smith

# Password method 2: Store the password in an encrypted file, and tell msmtp

# which command to use to decrypt it. This is usually used with GnuPG, as in

# this example. Usually gpg-agent will ask once for the decryption password.

#passwordeval gpg2 --no-tty -q -d ~/.msmtp-password.gpg

# Password method 3: Store the password directly in this file. Usually it is not

# a good idea to store passwords in plain text files. If you do it anyway, at

# least make sure that this file can only be read by yourself.

# Password method 4: Store the password in ~/.netrc. This method is probably not

# relevant anymore.

# Password method 5: Do not specify a password. Msmtp will then prompt you for

# it. This means you need to be able to type into a terminal when msmtp runs.

# A second mail address at the same freemail service

#account freemail2 : freemail
