naplpm on "[Plugin: WP Mail SMTP] Not working on WP Multisite"

Hi,

Thanks for the plugin, I used it on a couple of sites and it works great. I'm having trouble though to make it work on a WP multisite network. I installed the plugin, and "Network activated" it, I've set all the options (smtp.gmail.com), but the email sender keep using the email via sever form on the sender field of the emails sent by the system. Any idea?
