2.14.1.2.7. Configure mail in WordPress

By default, WordPress sends messages from the web server without authorization on behalf of an address such as wordpress@example.com. Such messages may be blocked either at the time of sending (see Invalid senders) or on the recipient's side.

You can configure correct sending in one of the following ways:

• Use the Simple SMTP, WP Mail SMTP or Post SMTP plugin to fully configure sending messages via SMTP (recommended method).
• Use the Change Mail Sender plugin to replace the default sender address with the mailbox address of an existing mail domain.

See WordPress administration (subsection "SMTP").

The simplest and fastest method. It can be configured via the control panel with minimal manual operations.

1. Open the WordPress admin panel.
2. In the "Plugins" section, install and activate the WP Mail SMTP plugin.
3. In the side menu, go to "WP Mail SMTP → Settings".
4. On the "General" tab, specify the sending settings and save your changes:
   1. Specify the sender's address, sender's name, and enable Return Path:
   2. As the mailer, select "Other SMTP":
   3. Specify the settings for connecting to the mail server:
      • "SMTP Host" — mail.adm.tools.
      • "Encryption" – "SSL".
      • "SMTP Port" — 465.
      • "Auto TLS" — enabled.
      • "Authentication" — enabled.
      • "SMTP Username" — mailbox name.
      • "SMTP Password" — mailbox password.
5. Check email sending (for example, in the "WP Mail SMTP → Tools" section using the "Send email" button).

1. Open the WordPress admin panel.
2. In the "Plugins" section, install and activate the Post SMTP plugin.

      • Transport Settings:

        • "Security" – "SMTPS".
        • "Authentication" — "Login".
      • Authentication:
        • "Username" — mailbox name.
