Insert Header Action
The
insert-header
action inserts a new header into a message. AsyncOS does
not verify the compliance to standards of the header you insert; you are

standards for email.
The following example inserts a header named
X-Company
with the value set to
My
Company Name
if the header is not already found in the message:
addXCompanyFilter:
if (not header('X-Company'))
{
insert-header('X-Company', 'My Company Name');
}
The insert-header() action allows the use of non-ASCII characters in the text of
the header, while restricting the header name to be ASCII (to comply with
standards). The transport encoding will be quoted-printable to maximize the
readability.
