Sendgrid集成 - 没有邮件发送

Question

我最近创建了一个SendGrid帐户，我想集成SendGrid for Python。

我尝试过两种类型的集成：Web API和SMTP Relay - 它们似乎都不起作用。我的消息未送达，因此我无法完成整合。 SendGrid说我的电子邮件还没有出现＆＃39;。

1。这是我用来测试WebAPI集成的脚本（是的，设置了环境变量）：

import sendgrid
import os
from sendgrid.helpers.mail import *

sg = sendgrid.SendGridAPIClient(apikey=os.environ.get('SENDGRID_API_KEY'))
from_email = Email("me@gmail.com")
to_email = Email("me@gmail.com")
subject = "Sendgrid test"
content = Content("text/plain", "Just a test")
mail = Mail(from_email, subject, to_email, content)
response = sg.client.mail.send.post(request_body=mail.get())
print(response.status_code)
print(response.body)
print(response.headers)

输出：

202

Server: nginx
Date: Fri, 09 Jun 2017 23:16:41 GMT
Content-Type: text/plain; charset=utf-8

2。这是SMTP中继集成测试的脚本：

import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText

msg=MIMEMultipart()
msg['From']='Test'
msg['Subject']='This is a test message.'
msg.attach(MIMEText('Hello World'))

fromaddr = 'me@gmail.com'
toaddrs  = 'me@gmail.com'

username = 'apikey'
password = "SG.[cut].[cut]"

server = smtplib.SMTP('smtp.sendgrid.net:587')
server.set_debuglevel(1)
server.starttls()
server.ehlo()
server.login(username,password)
server.sendmail(fromaddr, toaddrs, msg.as_string())
server.quit()

调试输出：

正如我在两种情况下所述，我的电子邮件因某些原因未送达。我的配置中是否缺少某些内容？
