How to block that sender irrespective of those numbers attacched to the IDs? Kindly help..

iam using Brightmail gateway 9.5

is the domain required by your oragnization? if not, block the domain.

Hi,

The domain is gmail.com..how we can block?

what SPAM policy has been activated for incoming messages?

You could create content filtering policies to block these patterns but I don't recommend it as spammer patterns change quickly.

Instead I would recommend ensuring the product has no rule updates issues (check logs for errors) and that you are following all the best practices in relation to spam control listed here: http://www.symantec.com/business/support/index?page=content&id=TECH90043

In particular to ensure Symantec has visibility into local missed spam variants I'd recommend

1) enabling Probe Participation - to convert invalid email addresses in your organisation into probe accounts.

2) forward any missed spam as an attachment to the appropriate address for your region - see here www.symantec.com/business/support/index?page=content&id=TECH83081

Any spam sent to these accounts will be eligible for potential filter creation by our analysts.
