无法在 Ubuntu 12.04 上通过 bash 脚本发送自动邮件：连接到 mx3.hotmail.com[65.55.37.72]:25：连接超时

首先，我对我的英语感到抱歉（我是法国人）。

我在用着Ubuntu 桌面 12.04。我仍在学习 Shell 脚本，因此可能在某个地方犯了一个非常简单的错误。

我正在尝试编写一个 shell 脚本，当磁盘空间使用率达到 80% 时向我发送电子邮件。（此脚本将在私人公司托管的远程服务器上的 cron 中使用）

为此，我使用 Postfix sendmail 命令。

问题是我甚至无法使用简单的命令行向我的 hotmail 地址发送测试电子邮件。

我检查了 /var/log/mail.log，这是我得到的结果（在终端中只使用了一个命令）：

这是我的命令行：

  $ echo foobar | sendmail -i [email protected]

起初我以为是Linux防火墙阻止了该端口，我使用以下命令进行检查：

$ sudo ufw status

这是我得到的：

État : actif

Vers                       Action      Depuis

25/tcp                     ALLOW       Anywhere (v6)

我不知道什么不起作用，请帮忙，我已经在这上面几个小时了......

这是 postfix 配置文件（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

# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

myhostname = bmerlet-Precision-T3600
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
mydestination = bmerlet-Precision-T3600, localhost.localdomain, , localhost
relayhost = 
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all

我不知道是否必须更改该文件中的某些参数，如果是的话，我不知道哪一个... :(

我在这里先向您的帮助表示感谢 ;）

端口 25 很可能被阻止或未被 hotmail 使用。您可以找到更好的参考，但请尝试备用端口，例如端口 465/587。
