I understand that you want to use the browsers default settings, i would also like an answer for that.
我知道您想使用浏览器的默认设置，我也想知道答案。
Meanwhile, you could do it manually.
同时，您可以手动完成。
MailAddress from = new MailAddress("[email protected]");
MailAddress to = new MailAddress("[email protected]");
MailMessage mm = new MailMessage(from, to);
mm.Subject = "Subject"
mm.Body = "Body";
SmtpClient client = new SmtpClient("proxy.mailserver.com", 8080);
client.Credentials = new System.Net.NetworkCredential("[email protected]", "password");
client.Send(mm);

Http Proxies control http traffic, they rarely have anything to do with SMTP at all. I've never heard of proxying SMTP before after all SMTP itself is intrinsically supports a chain of "proxies" to the destination SMTP server.
Http 代理控制 http 流量，它们与 SMTP 几乎没有任何关系。我从来没有听说过代理 SMTP，毕竟 SMTP 本身本质上支持到目标 SMTP 服务器的“代理”链。

If the only access you have to the internet is through HTTP, then pretty much the only way you'll be able to do this is by setting up a VPS (or equiv) with SSH on port 443 and using corkscrew (or putty) to tunnel ssh through. From there it is a simple matter to forward smtp traffic over your ssh tunnel.
如果您对互联网的唯一访问是通过 HTTP，那么几乎唯一能够做到这一点的方法就是在端口 443 上设置一个带有 SSH 的 VPS（或等效）并使用开瓶器（或腻子）来隧道 ssh 通过。从那里通过 ssh 隧道转发 smtp 流量是一件简单的事情。
Be aware that you may be violating the companies computing policy if you do this.
请注意，如果您这样做，您可能会违反公司的计算政策。
