[go] Best way use smtp via Proxy

[johandalabacka (Johan Dahl)]

@ext

err := s.Send(“测试 from socks5”, “from@xx.com”, string{“to@xx.com”}, “sockssmtp测试”)
if err != nil {
log.Fatalln(err)
}

But this is at the toplevel. The error must occur somewhere in the function and be returned. Where in the function is this error from?
