邮件设置正确我交叉验证了它们。系统托管在 CentOS 上，firewalld 被禁用。

更新 SMTP 设置

MAIL_DRIVER=smtp
MAIL_HOST=smtp.office365.com
MAIL_PORT=587
MAIL_USERNAME=dhprojects@dhdigital.co.in
MAIL_PASSWORD=xxx
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDR=dhprojects@dhdigital.co.in
MAIL_FROM_NAME=dhprojects@dhdigital.co.in
MAIL_REPLYTO_ADDR=dhprojects@dhdigital.co.in
MAIL_REPLYTO_NAME=SnipeIT
MAIL_BACKUP_NOTIFICATION_ADDRESS=xxx@dhdigital.co.in

Answer 1

我终于意识到问题出在我的 CentOS 上的 selinux 设置上。 SELinux 是强制执行的，所以它不允许我在那个特定端口上建立连接。一旦我禁用它，事情就开始工作了。
