问题内容
我有下面的 go 程序，它会发送电子邮件。凭证是正确的。我什至用curl测试了它们，我发现连接是成功的。请注意，tls 不是必需的。
package main
import (
"fmt"
"log"
"net/smtp"
)
const (
username = "[email protected]"
passwd = "password1111"
host = "mail.privateemail.com"
port = "465"
)
func main() {
from := "[email protected]"
to := []string{
"[email protected]",
}
msg := []byte("from: [email protected]\r\n" +
"to: [email protected]" +
"subject: golang testing mail\r\n" +
"email body: welcome to go!\r\n")
auth := smtp.plainauth("", username, passwd, host)
url := fmt.sprintf(host + ":" + port)
fmt.printf("url=[%s]\n", url)
err := smtp.sendmail(url, auth, from, to, msg)
if err != nil {
log.fatal(err)
}
fmt.println("mail sent successfully!")
}您能否告诉我为什么会出现以下错误？
read tcp 192.168.0.2:61740->198.54.122.135:465: wsarecv: an existing connection was forcibly closed by the remote host.
exit status 1
我尝试使用curl，我看到它连接到邮件服务器，但连接已关闭。
c:\GoProjects\goemail
λ curl -v --url "smtp://mail.privateemail.com:465" --user "[email protected]:password1111" --mail-from "[email protected]" --mail-rcpt "[email protected]" --upload-file sample.txt

解决方法
非常感谢您的回复。我从 https://www.php.cn/link/7104a226fe65be03fecf10f5bceff8a6 切换到实现 并且工作正常。我仍然不明白我做错了什么。我对 TLS 的看法是错误的 - 它被使用并且 go 方法也考虑到了它。
