ruby on rails - ActionMailer with NTLM auth (Exchange 2010) -


i have rails application using rails 4.2. how can send mail using exchange 2010 server ntlm authentication? according actionmailer docs:

:authentication - if mail server requires authentication, need specify authentication type here. symbol , 1 of :plain (will send password base64 encoded), :login (will send password base64 encoded) or :cram_md5 (combines challenge/response mechanism exchange information , cryptographic message digest 5 algorithm hash important information)

whatever auth method chose, keep getting error:

net::smtpsyntaxerror: 504 5.7.4 unrecognized authentication type

so found solution myself. kept getting error because exchange server use requires no authentication, should not pass authentication option @ all:

config.action_mailer.smtp_settings = {   address:              'smtp.yourdomain.com',   port:                 587,   domain:               'yourdomain.com' }

yes thats right: user_name, passwod , authentication left out.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself?
