Subject: SPAM tagging issue in SFI v3.5..
Date Posted: 27 April 2007 at 4:37pm
I have one email address in the "Unfiltered Emails" whitelist with the :tag option so the email header gets the SPAM tag. The way it worked in SFI v3.1.3.615, SPAM sent to the unfiltered email address got tagged as did all email addresses included in the email. In v3.5.. the unfiltered email address is the only one that gets the SPAM header tag, the other email addresses included in the email now bypass all filtering and end up in the users Inboxes.

I have had to remove the email address from the unfiltered emails whitelist.

Can you make the tagging in v3.5.. function the same as it did in v3.1.3?

Michael

The intended action in the new version is that the unfiltered message gets tagged and the rest quarantined.  I say intended because there seems to be times when the messages are, in fact, delivered.  I have not put this all together but it seems to depend on weather ot not the addresses are in the TO:, CC or BCC fields.  I started to look at this be then got sidetracted.  I think Thermo is on to something but as I stated, I am not clear on the exact issue yet.

Thermo,

You posted the log just as were were typing in the forum requesting for it

What we see right away is that this is not a single email with multiple recipients, but rather several, separate emails sent in the same session.

The new SpamFilter 3.5 is able to "split" emails with multiple recipients, so that the email is delivered for the allowed recipients, but is blocked for the others.

As this is not apparently the case here, we'll need to look into it further, as you may indeed have found a bug, since this is not an issue of splitting the email, but rather of handling multiple emails in the same session.

Updated to 3.5.3.665 but am still seeing mails not split up correctly. This mail was sent to 111@xxx.com with cc: to 222@xxx.com, 333@xxx.com, 444@xxx.com and 555@xxx.com. 555@xxx.com has the :SPAM tag in unfiltered E-Mails, 222@xxx.com and 444@xxx.com do not exist (and therefore are not listed in the "Authorized E-Mails" list).

I'm afraid at first glance we only patched the problem that occurred when the same SMTP session sent multiple separate emails, and did not address the problem with the tagging. We thought they fell under the same category, but judging from your log this appears not to be the same. We'll post an update here after looking into this further.
