How to email from a contact form
I have started the setup of a wordpress based site on Linode. I have setup a basic contact form (I happened to use Forminator) - it just has a name, email and comment field. I have even noted my email address in the fields related to where to send this notification. However, it doesn't seem to send anything when filled in. I realized that I assume I actually need an email account to send it from as well? If so, how/where do I associate an outgoing email account with the site/form. Also, is there a different form plug-in I could be using that might make things simpler?
You would need to configure SMTP to be able to send automated emails.
By Default Linode blocks port 25 to prevent spam from Linode instances. To solve this issue you need to contact Linode support to open port 25 or you can use a third-party SMTP provider. I have explained the detail on https://www.cloudlaya.com/blog/smtp-mail-servers/ for using the third-party SMTP provide to send the mail from your contact form.
