email_notices.send("test"," message from bluesky") hangs

[prjemian]

this works:

In [4]: email_notices.add_addresses("jemian@anl.gov", "prjemian@gmail.com")

In [5]: email_notices.addresses
Out[5]: 
['ilavsky@aps.anl.gov',
 'kuzmenko@aps.anl.gov',
 'mfrith@anl.gov',
 'jemian@anl.gov',
 'prjemian@gmail.com']

[prjemian]

so far:

In [6]: unix_cmd("echo mail test_message -s from_bluesky jemian@anl.gov prjemian@gmail.com".split())
Out[6]: (b'mail test_message -s from_bluesky jemian@anl.gov prjemian@gmail.com\n', b'')

[prjemian]

this does not return:

In [7]: unix_cmd("mail test_message -s from_bluesky jemian@anl.gov prjemian@gmail.com".split())

[prjemian]

Aha! things have changed...

(base) usaxs@usaxscontrol .../07/30 $ mail test_message -s from_bluesky jemian@anl.gov prjemian@gmail.com
Subject: ^C

[prjemian]

(base) usaxs@usaxscontrol .../07/30 $ mail -h
mail: option requires an argument -- h
Usage: mail -eiIUdEFntBDNHRVv~ -T FILE -u USER -h hops -r address -s SUBJECT -a FILE -q FILE -f FILE -A ACCOUNT -b USERS -c USERS -S OPTION users

[prjemian]

work this out offline

[prjemian]

Now using the mailx program. Use echo and a pipe to send the message now:

echo "another test" | mail  -s "from testing" jemian@anl.gov prjemian@gmail.com

[prjemian]

Can't use pipes in this context. Refactor with email package.
