Net :: SMTPSyntaxError：501提供的RCPT TO地址无效

Question

据我所知，我有问题，因为在电子邮件地址中不使用ASCII符号

示例：

Notifier.rb

mail(to: "Tamón ÄRUÄ <example@example.com>", subject: "Email subject")

我有什么建议可以处理这个案子吗？我更喜欢在地址中保留用户名。

Answer 1

根据[ToolStripItemDesignerAvailability(ToolStripItemDesignerAvailability.ToolStrip)] public class ToolStripDateTimePicker : ToolStripControlHost { private FlowLayoutPanel controlPanel; private DateTimePicker picker = new DateTimePicker(); public ToolStripDateTimePicker() : base(new FlowLayoutPanel()) { controlPanel = (FlowLayoutPanel)base.Control; controlPanel.BackColor = Color.Transparent; AutoSize = false; controlPanel.Controls.Add(picker); } public DateTime Value { get { return this.picker.Value; } set { this.picker.Value = value; } } protected override void OnSubscribeControlEvents(Control control) { base.OnSubscribeControlEvents(control); } protected override void OnUnsubscribeControlEvents(Control control) { base.OnUnsubscribeControlEvents(control); } } 文档，多字节编码应自动完成：http://guides.rubyonrails.org/action_mailer_basics.html#auto-encoding-header-values

可能有几件事要尝试：

1. 尝试将ActionMailer添加到控制器的第一行;
2. 尝试使用# encoding: utf-8 http://www.rubydoc.info/github/mikel/mail/Mail%2FMessage%3Atransport_encoding
