python smtp gmail authentication error (sending email through gmail smtp server)
gmail, python, smtp, smtplib
Solution
Port 587 obviously needs to be open, but it probably is (or you wouldn't have gotten the detailed error msg in question). Python 2.5 vs 2.6 should make no difference. I think the issue has to do with "solving a captcha" once on the computer for which logins are currently getting rejected; follow the detailed instructions at the URL in the error message, i.e., http://mail.google.com/support/bin/answer.py?answer=14257
Problem
I have the following code ``` import smtplib from email.mime.text import MIMEText smtpserver = 'smtp.gmail.com' AUTHREQUIRED = 1 # if you need to use SMTP AUTH set to 1 smtpuser = 'admin@myhost.com' # for SMTP AUTH, set SMTP username here smtppass = '123456' # for SMTP AUTH, set SMTP password here RECIPIENTS = ['online8@gmail.com'] SENDER = 'admin@myhost.com' msg = MIMEText('dsdsdsdsds\n') msg['Subject'] = 'The contents of iii' msg['From'] = 'admin@myhost.com' msg['To'] = ''online8@gmail.com'' mailServer = smtplib.SMTP('smtp.gmail.com',587) mailServer.ehlo() mailServer.starttls() mailServer.ehlo() mailServer.login(smtpuser, smtppass) mailServer.sendmail(smtpuser,RECIPIENTS,msg.as_string()) mailServer.close() ``` this code works fine on my desktop. but it failed with this error ``` smtplib.SMTPAuthenticationError: (535, '5.7.1 Username and Password not accepted. Learn more at\n5.7.1 http://mail.google.com/support/bin/answer.py?answer=14257 21sm4713429agd.11') ``` on my linux server. Not sure what went wrong, should i open some port on my linux server?
