Roberto,

When either tag spam and deliver option is checked, does SF still use the Authorized TO Emails to make sure the message has a valid recipient or does it ignore it and send it on to the destination server?

Thanks,
Dan B

Dan,

The "tag & deliver" options will always cause emails to be delivered (excluding viruses). If there is a match to *any* filter, including not being in the Authorized TO list, that means the email is spam and will thus be tagged as such before delivery.

Could there be an additional option setting in the ini to look at the Authorized To list and make sure the user is valid before it tags it and pass it on?   Maybe in an upcomming release?

Thanks,

Do you mean to (1) look at the Authorized TO list to see if a user is allowed there, and if so, (2) then check with your SMTP server to see if the user exists? If this was the question, I'm afraid not. With how SpamFilter is designed, the messae has to be fully received before an attempt is made to contact your SMTP server. Changing this behavior is rather complex and not likely to happen in the near future...

I don't use tag and delivery, so I may be talking rubbish, but I am pretty sure you wouldn't want tag and deliver where the Authorized TO white list is in use and there isn't a name match. This would just lead to a bounce, (back to a spoofed non-working email address most of the time) for the up-stream server, which can end up having a lot of queued up delivery failures.

You wouldn't need to query the up-stream server. If the Authorized TO white list is in use and there is no match, just drop the email. It does mean email admins need to manage the list and make sure it represents the user lists on the email servers being protected, but I can't see why else you would have it anyway.
