I am using the XML-RPC submission API to the Neos Server (optimization, AMPL, MILP, Cplex) and am receiving an error message to say that "CPLEX will not run unless you provide a valid email address."

Am I misinterpreting what I should do with the provided python template found on the Neos site[here] and here?

The relevant snippet of the Neos-provided .py file that I edited is below 

import sys
import xmlrpclib
import time

NEOS_HOST="www.neos-server.org"
NEOS_PORT=3332
CONTACT_EMAIL = 'me@mail.com'
INTERFACE = 'XML-RPC'
neos=xmlrpclib.Server("http://%s:%d" % (NEOS_HOST, NEOS_PORT))
...
(jobNumber, password) = neos.submitJob(xml, CONTACT_EMAIL, INTERFACE)
sys.stdout.write("JobNumber = %d \n" % jobNumber)

Besides the email error, my code works. I know because sometimes other solvers will return a result (it seems some solvers - though not CPLEX - don't require an email address)

An unrelated question For folks who are using this Neos server interface, what are the alternatives to using regex to parse the returned output file?

Thanks!

The Neos server team responded :

Add your email address into the xml that you are submitting. In your xml, add a line

<email> your.address@email.edu </email>

along with the fields like 

<model></model>
<data></data>

etc
