Exception in thread Thread-25 with my keylogger Python

Question

I have this remote keylogger and it works fine at first to send the emails but after a few minutes it stops sending emails and it throws me this error:

Exception in thread Thread-25:
Traceback (most recent call last):
  File "C:\Users\Lisandro0\AppData\Local\Programs\Python\Python37\lib\threading.py", line 926, in _bootstrap_inner

    msg = _fix_eols(msg).encode('ascii')
UnicodeEncodeError: 'ascii' codec can't encode character '\xf1' in position 312: ordinal not in range(128)

I would appreciate reading the code as it is short.

I appreciate any help

The error message is clear:

...Python37\lib\smtplib.py...UnicodeEncodeError: 'ascii' codec can't encode character '\xf1' in position 312: ordinal not in range(128)

It seems that smtplib has problem encoding your mail content.

I did some source code reading. In smtplib.py:

    def sendmail(self, from_addr, to_addrs, msg, mail_options=(),
                 rcpt_options=()):
        """This command performs an entire mail transaction.

        The arguments are:
            - from_addr    : The address sending this mail.
            - to_addrs     : A list of addresses to send this mail to.  A bare
                             string will be treated as a list with 1 address.
            - msg          : The message to send.
            - mail_options : List of ESMTP options (such as 8bitmime) for the
                             mail command.
            - rcpt_options : List of ESMTP options (such as DSN commands) for
                             all the rcpt commands.

        msg may be a string containing characters in the ASCII range, or a byte
        string.  A string is encoded to bytes using the ascii codec, and lone
        \\r and \\n characters are converted to \\r\\n characters.

Look here:

msg may be a string containing characters in the ASCII range, or a byte string

If you want to send mail of non-ascii content, you can encode the content into a byte string first.

(By the way, if I got it right, your question title is somewhat off the point, failing to grasp the key of your problem.)
