problems with yahoo mail

[forumisto]

Hello,

I sent mail messages with yahoo mail using a script wrote in python.
Since a month ago the result of the script is:

smtp.sendmail(sender_address, recpto_address, msg.as_string())
File "/usr/lib/python2.7/smtplib.py", line 742, in sendmail
raise SMTPDataError(code, resp)
smtplib.SMTPDataError: (550, 'Request failed; Mailbox unavailable')

What is the problem?

I have not found information in google to help me

Looks like its a problem at the yahoo end , have you tried logging in to the mail account via a browser to see if it is still working ?

I know yahoo mail has undergone some changes in the last few months you need to look a for a settings page in yahoo mail to see if they have change ports or security protocols in some way.

for example google mail now needs to be set to allow less secure apps to work with sendmail on the pi, may be yahoo has some thing similar.
