OpenEMM

From the documentation:
"The values for mailinglistID, targetID and emailSender will be taken from
the template in case you set
them to 0 and ““ (empty string for emailSender) respectively. All other
valid values will overwrite the values
of the template."

This is not true for the emailSender parameter. There is no code in
EmmWebservice to check for null or empty string, the value is always copied
from the argument of the WS-call.

Please update either the code or the documentation so that the function
works as specified.
