This example expands the previous one by setting the subject to be
[Bcc]
<original subject>
, and the return path set to
badbounce@home.org
:
momFilter:
if ((mail-from == '^johnny$') and (rcpt-to == '^sue$'))
{
bcc('mom@home.org', '[Bcc] $Subject', 'badbounce@home.org');
}
The alt-mailhost is the fourth parameter:
momFilterAltM:
if ((mail-from == '^johnny$') and (rcpt-to == '^sue$'))
{
bcc('mom@home.org', '[Bcc] $Subject', '$EnvelopeFrom',
'momaltmailserver.example.com');
}
Warning
The
Bcc()
,
notify()
, and
bounce()
filter actions can allow viruses through
your network. The blind carbon copy filter action creates a new message which
is a full copy of the original message. The notify filter action creates a new
message that contains the headers of the original message. While it is rare,
headers can contain viruses. The bounce filter action creates a new message
which contains the first 10k of the original message. In all three cases, the new
message will not be processed by anti-virus or anti-spam scanning.

To send to multiple hosts, you can call the

action multiple times:
