What is the best method to send any and all email from the website by mandrill api? I know there are several type of calls WP or WP plugins can use to send php/internal website mail. I would like to send absolutely all email via mandrill. Some plugins allow for naming smtp, but many do not (including Subscribe By Email) . . . for example, wp_mail() function or mail() functions etc.
I have looked at several plugins from another thread I started specifically on Subscribe By Email inquiry, but I have found none of them to work well (or they will only send for some methods and not others etc). I am looking for a all encompassing final solution to solve all outbound email issues will all plugins so that they will all actually work without worry about if they will have issues day-to-day…smile.
A proven/reliable way to do it per site AND alternately network-wide would be helpful.
