Ideally, on my new web hosting server, i want to completely disable any kind of email hosting for users domains. That will be something they have to sort for themselves using gmail, office 365, mail relay hosts such as sendgrid, or whatever...I just dont want any email my servers or my network. However, i do want contact forms to remain functional, on both static HTML and WordPress sites. 1. What are the minimum install requirement for a webhosting server for contact forms to work for example on wordpress website? 2. Does WordPress ability to use PHP mail make any difference to these minimum requirements? My thought is i need at least SMTP. However, i was wondering if i could have zero mail functionality on the server and force all customers to use offsite solutions for contact forms?
