EmailServices.sendMail causes a NPE, when sendFrom is missing

[Benjamin Jugl]

Hello all,

at the moment an NPE can be thrown by sending an Email (via the service 
"sendMail" without giving a value for "sendFrom".

I provided a patch for this in OFBIZ-10706 
<https://issues.apache.org/jira/browse/OFBIZ-10706>. This simply alters 
the service configuration, so that sendFrom is no longer optional.

Since this might interfere with some of your customer projects and the 
usage of sendMail therein, please give me some feedback, if this patch 
is in your interest.

Best wishes, Benjamin
