Problem sending SMTP Email - Raspberry Pi Forums

-

i have been trying send email using these codes.
receive following error code occasionally:

[errno -5] no address associated hostname

idea why? success rate of sending email 0-20%.
there socket or timeout error? or??
please advise. many thanks.

code: select all

#!/usr/bin/env python import smtplib time import sleep  gmail_user = 'xxx@gmail.com' gmail_pass = 'yyy' smtp_server = 'smtp.gmail.com' email_address1 = 'zzz@gmail.com' smtp_port = 587  def send_email(recipient, subject, text):         try:                    smtpserver = smtplib.smtp(smtp_server, smtp_port)                 smtpserver.ehlo()                 smtpserver.starttls()                 smtpserver.ehlo()                 smtpserver.login(gmail_user, gmail_pass)                 header = 'to:' + recipient + '\n' + 'from: ' + gmail_user                 header = header + '\n' + 'subject:' + subject + '\n'                 msg = header + '\n' + text + ' \n\n'                 smtpserver.sendmail(gmail_user, recipient, msg)                 smtpserver.quit()                 print ("successfully sent")         except exception, msg:                 print ("failure:  " + str(msg))         cnt = 0 while (cnt < 10):         send_email(email_address1, 'test email', 'thank you')         cnt = cnt + 1         sleep(5)

are intending send 10 mails in rapid succession , sleep 5 seconds?
while loop seems doing.

wouldn't surprised if gmail did reject being kind of spam or abuse. not have idea how deal deal such things.

happens when send mail once?
