[ANSWERED] IMAP not catching all SPAM

Hi All,
Yesterday I switch from UTM9 to Copernicus at home, by installing beta2.
Configured a IMAP/POP3 policy rule to scan home computers from spam.
Spam is not catching all SPAM.
Just now, I received 2 mail that are spam (one has attachment).
What's wrong?

[:@][:@][:@]

As i said, some spam are blocked.
Also, How can I control and block "Possible Spam" for IMAP protocol?
Let me know if you need log/screenshot.

Thanks.

Luk, you need to create two spam rules one for 'SPAM match', another for 'Possible spam' match with actions as prefix subject.

Thank you Saurabh.
I do not understand How to block Probable Spam And Spam on IMAP settings. On scanning rules, under POP3/IMAP scanning there is not Reject but only accept or prefix subject.

See attachments.

I am still receiving a lot of spam. On some email I can see headers added by Sophos while on other not.
Please help!

Hi iferara
please try quarantine option in your setting as you mention no reject for pop3/imap so try that one and also add one business rule of scan imap & pop3 if your not added in your firewall rule
Thanks

Hi Thiru and thank you for your answer and time.

See attachment. Policy rule has already been created (screen 1)
Quarantine is empty (screen 2). As I said, some spam are blocket (very few) while other are not (screen 3).

Also I would like to block Probable Spam to. I received few email where Sophos changed Subject to Probable Spam but I received them in my mailbox and I would like to block them or quarantine.

Thanks.

Another thing, why there is not reject option on IMAP/POP3 action?
This is strange. How can the Antispam delete/reject spam received by IMAP/POP3?

Can someone explain How Antispam settings works for IMAP/POP3 Clients?

This is very helpful for everyone. Thank you.

@lferrara: Neither Reject nor quarantine are available with POP3/IMAP as actions. Available actions are accept or prefix subject.

Attached screen showing adequate content scanning rules to mark SPAMs and possible SPAMs. (assuming you have created email client business policies, i.e. firewall rule)

Luk, Can you please share the spam emails which you were receiving, so that we can check the same in our local lab with IMAP scanning.
You can PM me the same if you cannot share the samples publicly.

Regards,
Prateek
