header - Setting Return-Path with Python sendmail for a MIME message -

-

hi set "return-path" header mime message send python. basically, tried :

message = mimemultipart() message.add_header("return-path", "something@something.com") #...  smtplib.smtp().sendmail(from, to, message.as_string())

the message receive have "return-path" header set same content "from" one, if explicitly add "return-path" header.

how can set "return-path" header mime message sent through smtplib's sendmail in python ?

thanks in advance.

return-path set smtp protocol, it's not derived message itself. it'll envelope address setups.

the proper way accomplish is:

msg = email.message_from_string('\n'.join([     'to: michael@mydomain.com',     'from: michael@mydomain.com',     'subject: test email',     '',     'just testing' ])) smtp = smtplib.smtp() smtp.connect() smtp.sendmail('something@something.com', 'michael@mydomain.com', msg.as_string())

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
