通过 crontab 发送电子邮件失败

通过 crontab 发送电子邮件失败

我在 crontab 中放置了一个脚本，当备份脚本完成时，它会向我发送一封电子邮件。

该脚本自行运行时确实会向我发送该电子邮件。

然而，当它在 crontab 中运行时我得到

sendmail: 450 Requested mail action not taken: mailbox unavailable

来自系统日志

这是 crontab 的一部分

  # m h  dom mon dow   command
   # Run my backup script at 10 a.m every day
   0 10 * * * /home/andy/bin/Backup_18_04.sh
  # Run my backup script at 8 p.m every day

  0 20 * * * /home/andy/bin/Send_Email.sh

这是我的脚本。

#!/bin/bash
# Ubuntu_Mate 18.04 LTS
#
# Send an email using a script
# Make sure there are several blank lines between Subject and the message.!!
CONTENT="Backup to Maxtor Drive has occured."
ssmtp -t << EOF

Subject: Backups to Maxtor Drive

怎么了？

答案1

它可能不够优雅，但是它在我的系统上确实有效。

#!/bin/bash
# Ubuntu_Mate 18.04 LTS
# 
# Backup sounds
cd /usr/share/sounds/My_Sounds/
echo yyy | sudo -S zip -u My_Sounds.zip *.mp3 *.wav
sudo zip -u My_Sounds.zip *.mp3 *.wav
# Send me email of the backup

CONTENT="Backup to Maxtor Drive has occured."
echo "Sending email."
/usr/sbin/ssmtp -t << EOF
To: [email protected]
From: [email protected]
Subject: Backups to Maxtor Drive
