내 postfix 메일 구성이 정확합니까? (이메일은 수신되지 않습니다)

Question

나는 매우 리눅스 초보적인 사람이고 당신이 제공할 수 있는 도움과 인내심에 크게 감사드립니다.

우분투 21.04를 실행 중입니다.

웹 호스트의 이메일 설정 지침:

postfix를 통해 메일을 보낼 수 있도록 설정하려고 합니다.

이것은 내 구성입니다.

nano /etc/postfix/main.cf

# See /usr/share/postfix/main.cf.dist for a commented, more complete version


# Debian specific:  Specifying a file name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

readme_directory = no

# See http://www.postfix.org/COMPATIBILITY_README.html -- default to 2 on
# fresh installs.
compatibility_level = 2


smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
myhostname = <mydomain>.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = $myhostname, mail.<mydomain>.com, <computer name>, localhost.localdomain, localhost
relayhost = [mail.<mydomain>.com]:465
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all


# Enable SASL authentication
smtp_sasl_auth_enable = yes
# Disallow methods that allow anonymous authentication
smtp_sasl_security_options = noanonymous
# Location of sasl_passwd
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd

# Enable STARTTLS encryption
smtp_use_tls = yes

# where to find CA certificates
smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt

smtp_tls_wrappermode = yes

smtp_tls_security_level = encrypt

다음을 실행하여 테스트 이메일을 보냅니다.

echo "Test Mail" | mail -s "Test Email" <[email protected]>

그런데 이메일을 받지 못했습니다(스팸메일함도 확인했습니다).

다음은

nano /var/log/mail.log
