我试图使用一个脚本,我发现ping电子邮件,以确保他们存在。你知道吗
with open(input_list, 'r') as f:
reader = csv.reader(f)
for row in reader:
address = row[0]
person_name = row[1]+' '+row[2]
company = row[4]
match = re.match('^[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$', address)
print("Email for ", person_name)
print(address)
if match == None:
synt = 'Bad Syntax'
warnings.warn(address + " has bad syntax.")
else:
synt = 'Good syntax'
dom = re.search("@(.*)$", address).group(1)
print(dom)
try:
records = dns.resolver.query(dom, 'MX')
mxRecord = records[0].exchange
mxRecord = str(mxRecord)
except:
warnings.warn("Issue contacting domain")
pass
# Get local server hostname
host = socket.gethostname()
# SMTP lib setup (use debug level for full output)
server = smtplib.SMTP('smtp-mail.outlook.com',587)#will need this for mail sending
while True:
try:
server.set_debuglevel(0)
# SMTP Conversation
server.connect(mxRecord)
server.helo(host)
server.mail('me@domain.com')
code, message = server.rcpt(str(address))
server.quit()
if code == 250:
print('Success')
new_row = [address, person_name, company, synt, 'Ping Successful']
email_data.append(new_row)
with open('cseresult2.csv', 'a+', newline='') as mess:
writ = csv.writer(mess, dialect='excel')
writ.writerow(email_data[-1])
else:
print('Bad')
new_row = [address, person_name, company, synt, 'Ping Bounced']
email_data.append(new_row)
with open('cseresult2.csv', 'a+', newline='') as mess:
writ = csv.writer(mess, dialect='excel')
writ.writerow(email_data[-1])
except:
continue
break
print()
print('================')
print()
time.sleep(3)
代码基本上可以正常工作。但是,如果没有while循环,会出现很多超时错误:
TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
while循环已经解决了这个问题,但是现在它将挂在一封电子邮件上,而不是遍历列表的其余部分。这是一个项目,所以任何帮助,使其移动将不胜感激。你知道吗
如果
while
循环遇到任何类型的持久性错误,它将被设置为永远继续。在try
块中有很多代码,因此有很多情况可能会发生这种情况(例如,无法连接到电子邮件服务器、无法打开csv文件等)。如果没有更多的信息,我不能肯定这是发生了,但它肯定不会伤害到解决这个问题。你知道吗因为您关心的唯一错误是
TimeoutError
,所以应该显式地捕获该错误,并且continue
仅在这种情况下。对于所有其他错误,要么打印错误并中断循环,要么让错误冒泡。在创建服务器实例时,还应该将超时设置为一个正常值。最后,最好使用for
循环,如果超时在一段时间后仍未解决,则该循环将结束;即使是在持久的TimeoutError
情况下,也不希望永远尝试:如果您想知道默认超时是什么,可以执行以下操作:
响应是默认超时,以秒为单位。值
None
表示您将永远不会超时,但您的情况似乎不是这样。你知道吗相关问题 更多 >
