I'm running a simple playbook to report on server configurations which is 
formatted into an html file from a template.  I use the mail module to 
attach the html file into the body of the mail as follows:












*- hosts: localhost  tasks:    - name: Send e-mail      local_action: 
mail        port=25        headers="Content-type=text/html"        
subtype=html        from="x...@xxx.com <x...@xxx.com>"        to="x...@xxx.com 
<x...@xxx.com>"        subject='Server Report'        body="{{ 
lookup('file', '/tmp/report.html') }}"*

When I run this on a group of 13/14 servers the play runs fine, mail is 
sent and received as expected.  If I add more servers to the group, the 
initial parts of the playbook run fine, but then it fails when attempting 
to send the mail.  I've not seen this with any other playbooks or roles I 
have on the same server, emails seem to send out just fine

/var/log/messages shows the following abrtd errors which appear to come 
from python and ansible_module_mail.py:

What I don't know is whether this is ansible and/or python, or perhaps my 
poor implementation of the mail module.  Google search has not returned any 
worthy suggestions or causes.  Could I be missing something server side - 
python config or sendmail?
Does anyone have any ideas?
