The bounce address is used for bounce handling, so it depends, how important the OpenACS built-in bounce handling is in your application.
one possibility would be to configure a parameter "BounceToSender", which could deactivate the OpenACS bounce handling without much hacking around.
another possibility would be to use a custom mail sending proc, in case, you want to send this kind of mail just from one certain application/page/... one could provide an additional parameter to send_immediately for this purpose.
a next possibility would be to make postfix accepting the bounce address, which is also configurable via the package parameter EnvelopePrefix of acs-mail-lite, which defines the result of bounce_prefix (see below).
Probably, there are many more options.
-g
d_proc -public bounce_address {
-user_id:required
-package_id:required
-message_id:required
} {
Composes a bounce address
@option user_id user_id of the mail recipient
@option package_id package_id of the mail sending package
(needed to call package-specific code to deal with bounces)
@option message_id message-id of the mail
@return bounce address
} {
return "[bounce_prefix]-$user_id-[ns_sha1 $message_id]-$package_id@[address_domain]"
}
