vmounts on "[Plugin: WP Mail SMTP] Reconfigure "From" address?"

I have the same problem.
I am running multi-site and have setup several blogs that are successfully using WP-Mail-SMTP. This latest blog however I am using a different address (and SMTP server) than I had in the past. When I send a test mail it tries to send using the settings of the root blog and it doesn't matter how many times I change it. The odd thing is that when I refresh the options page the correct values are still showing in the fields. Is this plugin perhaps not multi-site compatible?
