How do I send a mail via mailx & subprocess?
email, python, subprocess
Solution
you can use smtplib
import smtplib
# email options
SERVER = "localhost"
FROM = "root@example.com"
TO = ["root"]
SUBJECT = "Alert!"
TEXT = "This message was sent with Python's smtplib."
message = """\
From: %s
To: %s
Subject: %s
%s
""" % (FROM, ", ".join(TO), SUBJECT, TEXT)
server = smtplib.SMTP(SERVER)
server.set_debuglevel(3)
server.sendmail(FROM, TO, message)
server.quit()
If you really want to use subprocess( which i advise against)
import subprocess
import sys
cmd="""echo "test" | mailx -s 'test!' root"""
p=subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE)
output, errors = p.communicate()
print errors,output
Problem
I am EE, trying to write a script to simplify file checks using Python. For some reason, our IT will not let me gain access to our SMTP server, and will only allow sending mail via `mailx`. So I've thought of running `mailx` from Python and send it, in the same way that it works in my console. Alas, it gives an exception. See Linux log below: ``` Python 3.1.1 (r311:74480, Dec 8 2009, 22:48:08) [GCC 3.3.3 (SuSE Linux)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import subprocess >>> process=subprocess.Popen('echo "This is a test\nHave a loook see\n" | mailx -s "Test Python" mymail@mycomopany.com') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/depot/Python-3.1.1/lib/python3.1/subprocess.py", line 646, in __init__ errread, errwrite) File "/depot/Python-3.1.1/lib/python3.1/subprocess.py", line 1146, in _execute_child raise child_exception ``` I am a newbie to Python (now migrating from Perl). Any thoughts?
