我的 postfix 邮件配置正确吗？（未收到电子邮件）

我是一个 Linux 新手，非常感谢您提供的任何帮助和耐心。

我正在运行 Ubuntu 21.04

来自网络主机的电子邮件设置说明：

我正在尝试设置通过 postfix 发送的邮件。

这是我的配置：

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

我通过运行以下命令发送测试电子邮件：

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

但是，我从未收到过电子邮件（我检查过我的垃圾邮件文件夹）。

以下是

nano /var/log/mail.log

在此先感谢您提供的任何帮助。
