我想制作一个脚本，使用 nxapi 读取我的 Nintendo Switch 好友列表，并在我的配置文件的“观看”部分中有人上线时向我发送电子邮件。我的网站由 DreamHost 托管。我在尝试发送测试电子邮件时不断收到 SMTPRecipientsRefused 错误。
剧本：

except FileNotFoundError:
print("No configuration file! Create a file at", configpath, "and follow the format detailed on the project page.")
exit()
# Setting up SMTP if email is enabled
mailsender = None
if config['email']['enabled'] == True:

print("Connecting to email server")
try:
mailsender = smtplib.SMTP(config['email']['server'], config['email']['port'])
print("Logging in to email server")
mailsender.login(config['email']['user'], config['email']['pass'])
mailsender.ehlo_or_helo_if_needed()
mailsender.starttls()

print("Last run time:",lastchecktime.strftime("%b %d, %Y at %I:%M %p"))
def mailsendonline(username, game, lastchange):
message = MIMEMultipart()
message['From'] = config['email']['sendfrom']
message['To'] = config['email']['sendto']
message['Subject'] = "Switch Friend Watch: " + username + " is online playing " + game
# Create MIMEText object for the message body
body_text = MIMEText("Your friend " + username + " is now online playing " + game + ". \nLast status update: " + lastchange.strftime("%b %d, %Y at %I:%M %p") + "." + "\n\nSwitch Friend Watch\na tool by LittleBit", 'plain')
message.attach(body_text)
# Send the email using the provided SMTP object (mailsender)
mailsender.sendmail(config['email']['sendfrom'], config['email']['sendto'], message.as_string())
# Optional: Print a success message
print("Email sent successfully!")
# Checking for watched users online, and making sure their status has changed since the last time the script ran
for friend in friends:
for watched in config['watched']:
if datetime.datetime.fromtimestamp(friend['presence']['updatedAt']) > datetime.datetime.fromisoformat(config['lastcheck']):
if watched['type']=="name":
if friend['name']==watched['value']:
if friend['presence']['state']=="ONLINE":
print(friend['name'],"is watched and is online!")
if config['email']['enabled']:
mailsendonline(friend['name'], friend['presence']['game']['name'], datetime.datetime.fromtimestamp(friend['presence']['updatedAt']))
else:
print(friend['name'],"is watched but isn't online.")
elif watched['type']=="id":
if friend['id']==watched['value']:
if friend['presence']['state']=="ONLINE":
print(friend['name'],"is watched and is online!")
else:
print(friend['name'],"is watched but isn't online.")
else:
print(friend['name'],"'s status hasn't changed since the script last ran, ignoring. Last change: ",datetime.datetime.fromtimestamp(friend['presence']['updatedAt']).strftime("%b %d, %Y at %I:%M %p"),sep="")
config['lastcheck'] = datetime.datetime.now().isoformat()
if config['email']['enabled']:
if config['email']['sendtest']:
print("Email enabled with sendtest flag set, sending a test email!")
hashtagnumber=random.randint(1000,9999)
mailsendonline("Player#"+str(hashtagnumber), "TestGame", datetime.datetime.now())
config['email']['sendtest']=False
with open(configpath, 'w') as outfile:
yaml.dump(config, outfile, default_flow_style=False)
我希望脚本能够顺利完成，并且我的收件箱中会出现一封电子邮件。
发生的事情是一个例外：
Traceback (most recent call last):
File "/home/jaherron/code/python/switchfriendwatch.py", line 89, in <module>
mailsendonline("Player#"+str(hashtagnumber), "TestGame", datetime.datetime.now())
File "/home/jaherron/code/python/switchfriendwatch.py", line 57, in mailsendonline
mailsender.sendmail(config['email']['sendfrom'], config['email']['sendto'], message.as_string())
File "/usr/lib/python3.11/smtplib.py", line 901, in sendmail
raise SMTPRecipientsRefused(senderrs)
smtplib.SMTPRecipientsRefused: {'[My personal email]': (554, b'5.7.1 <[My personal email]>: Recipient address rejected: Access denied')}
我通过使用普通的 SMTP 端口 465 解决了这个问题。Gmail 显然拒绝使用 STARTTLS 安全方法来接收电子邮件。
这是我的代码的最新版本。
