This page documents the SENDMAIL_F_OPTION configuration setting in FormMail.

SENDMAIL_F_OPTION is a LEAVE setting, which means...

LEAVE

you can change this setting if you really want to and know what you're doing, but we recommend that you leave this setting unchanged.

Controls use of "-f" option for sendmail.

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.
