Therefore, users must make sure specified headers are safe and contains headers only. Never start mail body by putting multiple newlines. When sending mail, the mail must contain a From header. Failing to do this will result in an error message similar to Warning: The From header sets also Return-Path under Windows.

For example, this can be used to set the envelope sender address when using sendmail with the -f sendmail option. This parameter is escaped by escapeshellcmd internally to prevent command execution. For security reasons, it is recommended for the user to sanitize this parameter to avoid adding unwanted parameters to the shell command.


Since escapeshellcmd is applied automatically, some characters that are allowed as email addresses by internet RFCs cannot be used. The user that the webserver runs as should be added as a trusted user to the sendmail configuration to prevent a 'X-Warning' header from being added to the message when the envelope sender -f is set using this method.
