我正在尝试关注this example:
package main
import (
"gopkg.in/gomail.v2"
)
func main() {
m := gomail.NewMessage()
m.SetHeader("From", "from@example.com")
m.SetHeader("To", "to@example.com")
m.SetHeader("Subject", "Hello!")
m.SetBody("text/plain", "Hello!")
d := gomail.Dialer{Host: "localhost", Port: 587}
if err := d.DialAndSend(m); err != nil {
panic(err)
}
} //main
我收到了这个错误:
panic: 454 4.7.0 TLS not available due to local problem
goroutine 1 [running]:
panic(0x244ca0, 0xc820010b20)
/usr/local/Cellar/go/1.6/libexec/src/runtime/panic.go:464 +0x3e6
main.main()
/Users/kaiyin/IdeaProjects/gomail/main.go:19 +0x342
exit status 2
我也尝试过禁用TLS和SSL:
d := gomail.Dialer{Host: "localhost", Port: 587, SSL: false, TLSConfig: nil}
但错误仍然存在。
我查看了mail.log(来自osx 10.10上的postfix):
Apr 7 14:28:05 kaiyins-mbp postfix/smtpd[64525]: warning: No server certs available. TLS won't be enabled
Apr 7 14:28:05 kaiyins-mbp postfix/smtpd[64525]: connect from localhost[::1]
Apr 7 14:28:05 kaiyins-mbp postfix/smtpd[64525]: lost connection after STARTTLS from localhost[::1]
所以我生成了这样的证书:
cd /etc/postfix
sudo openssl req -new -outform PEM -out smtpd.cert -newkey rsa:2048 -nodes -keyout smtpd.key -keyform PEM -days 365 -x509
并更改了后缀设置:
smtpd_enforce_tls = no
smtpd_tls_loglevel = 1
smtpd_use_tls = yes
smtpd_tls_key_file = /etc/postfix/smtpd.key
smtpd_tls_cert_file = /etc/postfix/smtpd.cert
现在我得到了一个不同的错误:
panic: x509: certificate signed by unknown authority
goroutine 1 [running]:
panic(0x26e3c0, 0xc8203e4b80)
/usr/local/Cellar/go/1.6/libexec/src/runtime/panic.go:464 +0x3e6
main.main()
/Users/kaiyin/IdeaProjects/gomail/main.go:19 +0x32f
exit status 2
我尝试按照此处的说明生成证书:http://www.akadia.com/services/ssh_test_certificate.html
我又得到了一个错误:
panic: x509: certificate is valid for Kaiyin Zhong, not localhost
goroutine 1 [running]:
panic(0x26a7e0, 0xc8203e6800)
/usr/local/Cellar/go/1.6/libexec/src/runtime/panic.go:464 +0x3e6
main.main()
/Users/kaiyin/IdeaProjects/gomail/main.go:19 +0x32f
exit status 2
我认为我的服务器名称错误,所以我重新做了一遍,将服务器FQDN设置为localhost:
Common Name (e.g. server FQDN or YOUR name) []:localhost
然后我回到了上一个错误:
panic: x509: certificate signed by unknown authority
goroutine 1 [running]:
panic(0x26e3c0, 0xc8203e6800)
/usr/local/Cellar/go/1.6/libexec/src/runtime/panic.go:464 +0x3e6
main.main()
/Users/kaiyin/IdeaProjects/gomail/main.go:19 +0x32f
exit status 2
答案 0 :(得分:1)
设置InsecureSkipVerify选项:
package main
import (
"crypto/tls"
"gopkg.in/gomail.v2"
)
func main() {
d := gomail.NewDialer("smtp.example.com", 587, "user", "123456")
d.TLSConfig = &tls.Config{InsecureSkipVerify: true}
// Send emails using d.
}
