SMTPlib Sender Refused?

Hi,

I'm trying to send an email message with python, and I'm getting this
error:

Traceback (most recent call last):
File "wa.py", line 430, in ?
main()
File "wa.py", line 425, in main
smtp.sendmail(fromaddr, to, msg.encode('utf-8'))
File "/usr/local/lib/python2.4/smtplib.py", line 680, in sendmail
raise SMTPSenderRefused(code, resp, from_addr)
smtplib.SMTPSenderRefused: (503, 'sender already given',
'm*@mydomain.com')

What is causing this?

Thanks!
Erik

This error is given when the MAIL command has already been sent.

Usually this is indicative of some command failing (maybe invalid rcpt
to:??) and retrying without sending the RSET command.

Try connecting manually and see what you get.
