我不明白为什么我的 AWS EC2 ( Ubuntu 14.04.1 LTS (GNU/Linux 3.13.0-32-generic x86_64))上的 cron似乎无法通过 sSmtp 向 AWS SES 发送电子邮件。
这有效：echo "test" | ssmtp my@myemail.com我从本地用户那里收到一封电子邮件。
这有效：echo "test" | sudo ssmtp my@myemail.com我收到一封来自 root 的电子邮件。
但是，当 cron 运行并尝试发送电子邮件时，我什么也没有得到，这出现在 syslogs:sSMTP[14608]: 554 Transaction failed: Missing final '@domain'或有时：554 Transaction failed: User name is missing: 'Cron Daemon <root>'。
cron 试图以谁的身份发送电子邮件？我会认为它是root。
/etc/crontab：
MAILTO="me@myemail.com"
（我也试过MAILTO=root）
/etc/ssmtp/revaliases：
root:me@myemail.com:email-smtp.us-east-1.amazonaws.com:465
me:me@myemail.com:email-smtp.us-east-1.amazonaws.com:465
/etc/ssmtp/ssmtp.conf：
root=me@myemail.com
mailhub=email-smtp.us-east-1.amazonaws.com:465
rewriteDomain=myemail.com
hostname=myemail.com
#UseSTARTTLS=YES

FromLineOverride=YES …我在 AWS 上运行 Ubuntu 12.10 (GNU/Linux 3.5.0-21-generic i686)。
