客户端没有作为此发件人发送的权限

Question

平台: Arch Linux Cron: cronie Mail: msmtp

我发现将cron输出发送到Office 365托管的邮箱会产生以下错误，即使通过CLI发送邮件运行良好：

Apr 01 04:41:10 prod crond[306]: msmtp: the server did not accept the mail
Apr 01 04:41:10 prod crond[306]: msmtp: server message: 550 5.7.1 Client does not have permissions to send as this sender
Apr 01 04:41:10 prod crond[306]: msmtp: could not send mail (account default from /etc/msmtprc)

Apr 01 04:41:10 prod CROND[3212]: pam_unix(crond:session): session closed for user postgres

Answer 1

解决方案是，除了MAILTO之外，我还需要向crontab添加以下内容：

MAILFROM=cron@domain.com
