我在配置文件中找到了解决方案

$config['smtp_server'] = 'tls://mail.com'

它应该是 tls 而不是 ssl :)

这不应该是：ssl://mail.test.com:587

是这个吗？ssl://localhost:587

我相信roundcube需要将“localhost”设置为邮件服务器地址，但从日志看来，它可能被设置为使用“mail.test.com”

如果 mail.test.com 是您的 VPS - 仅存在于 IP 上，而不存在于 DNS 上 - 则无法使用该地址路由到它，因此同一服务器上的 roundcube 将无法找到它。

如果 roundcube 在同一台服务器上，它使用的邮件服务器地址无论如何都应该设置为“localhost”。
