In Brightmail Gateway 8.x there are a couple ways you could do this. First you can look at the "Reputation" tab, under "IP Reputation Lookup" and enter the IP here.

Alternatively you can go to http://ipremoval.sms.symantec.com/lookup/ and look up the IP here.

Hope this helps!

i've done it at both of this earlier the ip seems to be ok there but it was still blacklisted by the global reputation

seems weird to me this way
please advice

any help guys?

I'm sorry for not getting back to you yesterday. How are you adding them to the allowed sender list? By domain or IP?

If you have added them by domain, try adding them by IP and see if this bypasses the Bad Senders list. 

i've tried adding it detects it as the thing i post up but the mail is still blocked

Hi,

sounds like some configuration problem. As Tom said, if you whitelist the sender based on IP address (not domain or email address) that should be enough to achieve the desired results.
Can you post the verdict you get when using IP address instead of email adress or domain?
This behavior is explained under Appendix A "Verdict combinations" on the SBG administration guide.

Hello wenfeng

As mentioned by Federico the mail should go through if the sender domain / IP is added to the 'Local Good Senders'.
  Admin guide under 'Verdict combinations' on page 521 (Table A-5). Download the manual from here.

If I recall correctly however, the 'Symantec Global Bad Sender' has 'Reject SMTP connection' action set by default.  The screen-shot above shows 'Static Delete'.
From the admin guide I also see that the 'Delete" has a higher priority than 'Deliver Normally' (page 518, Table A-3).  Based on this table, if you have two verdicts triggered - one with delete action, the other with deliver - the mail is going to be deleted.

Will check my SBG once in the office, and post again as a confirmation.

Cheers.

This same issue i have recently with one of my customer, I tried with both way by using domain name or IP to bypass symantec globle bad sender, but did not worked.

So to solve this i have created new group with that specific mail ID and created one compliance policy saying "for all measage" to this group "deliver message normally", by doing this i am able to receive that mail.

Hi,

just want to add that is very important for SBG to see the original source IP address of inbound SMTP connections in order to take advantage of IP reputation and other features. Also have a look at the following KB article for other suggestions:
