not getting user confirmation emails

Most likely an SPF problem. Please read WordPress emails are sent but not received

Don’t think so – the site via your plugin is sending all kinds of emails and I see them in the email log. I do not see any new user registration emails in the email log
Please help

new data – when I manually add a user – I get a new user registration message – so something is strange

Did you setup your SPF like the article said?

yes – I am working on some other issues – if it ends up being your plugin – I will let you know
I really like the plugin and hope it is not related
