This plugin seems to do a fine job of combating the problem of having hosting account information in wordpress’s emails that are sent out.
However, in gmail only, I still see a little bit of the problem.
I suggest you test thoroughly with gmail. It adds an extra line to the email “from” field which is not desirable. I will gladly send pictures if you want.
Also: to the person having trouble with contact form 7, I had very little problems installing the plugin (it works great other than the above stated issue.)
I suggest you start from ground up and remove any changes you made and revert them back to normal. I didn’t have to change anything crazy. May have a different hosting provider though… I have bluehost.
Sincerely Yours,
Nick
