Précis

Controls use of "-f" option for sendmail.

Description

SENDMAIL_F_OPTION controls whether to use the "-f" option when sending mail.

Some servers use a Mail Transfer Agent called "sendmail" and some of these require the "-f" option to be provided - this option tells sendmail the "From" user or sender.

FormMail originally supported this feature using the "mail_options" setting inside your HTML forms. That was a silly place for us to put this feature! It's a server configuration, so it should live in the configuration section of FormMail, not in your forms.

Set SENDMAIL_F_OPTION to true to tell FormMail to specify the "-f" option when sending mail or set it to false to prevent FormMail from specifying it.

Review the email logic description for more information.
