Hi Ashraf,

Bounce Attack Prevention (BAP) feature is described in detail, including instructions on how to configure it, in the topic titled "About defending against bounce attacks" on page 163 in Symantec Brightmail Gateway (SBG) 8.0 Administration Guide.

Adnan

Things to be considered:

1. Do you have 3rd parties sending on your behalf - e.g. have you farmed out marketing e-mails to a 3rd party?  If so, their e-mails won't have the correct BAP data when they bounce back.

2. Do you have more than one control center / Scanner farm?  I've had problems with this & BAP.

Good points.

For #2, if you set the same value of "Bounce attack prevention seed" on all the control centers for BAP to work properly as indicated in the Admin Guide:

QUOTE:

Warning: If you are running your inbound and outbound messages on different
Scanners with different Control Centers, repeat steps 1 through 3 for each
Control Center, using the same seed value. This ensures that all inbound and
outbound servers are calculating the same tags for validation.

UNQUOTE:

Can you please share what problems did you have and how were those resolved?

Regards,

Adnan
