SMG Audit Whitelist

I need a solution

Hello,

Is there a method or process available to use the whitelist in SMG 10.5.4 and verify the number of times a whitelisted entry has actually passed-through the SMG to my local domain?

I'm certain we don't use every entry in our whitelist or some of them were for products we don't even use anymore, I would like to validate and remove any that haven't been used in 3 to 6 months.

Any assistance you can provide would be most appreciated.

Thank you,

Rod

Is there anyway to do this? I need to compare our list to our internal dns records, which means a lot of copying and pasting. I don't understand if there is an import button why there is no export button?

Regular Expression - Maximum number of matches

I need a solution

Hello Folks,

I've recently added a regex to our system to flag messages with numbers those contain 10 digits.

\b^[0-9]{10}$\b appears to work well for this - but up to 40 matches. When there's more than 40 items inside a message, the pattern doesn't work. How - do you think - should I go ahead with making this work for messages with more than 40 matching items? What am I missing?

Thanks.

Excessive spam, all tagged with "AAAAAA==" - is something not working?

I'm seeing an unusually high amount of obvious spam avoiding my filters.  They all contain the header:

X-Brightmail-Tracker: AAAAAA==

which suggests to me that something is not getting scanned at all?  Normally, it's a huge long random jumble after the :

Obviously it's connecting and all working, otherwise the header would not be there at all, but what might be going wrong here?

I need a solution

Hello, I have configured Messaging Gateway connected with my Symantec DLP, so all emails now sends to DLP for analyse. The issue accrued when I turn on journaling in my main mail server (journaling server is separated stand alone mail server) and starts bulk emailing. Because of huge amount of emails the queue is increasing and emails sticking in mail server. So, is there any possibility to exclude some email addresses (especially journaling address) from checked by DLP. I am added exclusions in all policies in DLP but it don't help. I just want don't send all emails from journaling service to DLP. Is it possible?

I need a solution

Hi,

we use the mailgateway (10.6) as an appliance on vsphere and we turned on the "DNS-Validation" feature (option 1 and 4) a few days ago.

now i want to report which IP's and Mail-Addresses were affected.

we found one solution to monitor part of this options in the message audit logs (optional filter: action taken and value: reject messages). 
but there i got only mails which are rejected with the entry: "mail-from domain does not exist in dns"

a second way could be found in the logs: log type: mta, severity: warning
there are entries like: LUA: RDNS: RDNS lookup for connecting IP nnnnnnn returned SERVFAIL 

Is it possible to generate a report which ip-addresses AND email addresses were affected by this setting?

thanks,

best regards

Emails from my domain blocks by the Symantec antispam filter

I need a solution

Greetings

I'm a system administrator in the company Sirius Extrusion. My company has clients that use your antispam filter. Unfortunately your antispam filter has started to block our emails without any reason.  My colleagues receives "553 Message filtered" response. Our domain isn't in any spam database, it has SPF record and our email server isn't open relay.

Could you please stop to block our emails and add our domain to the your whitelist?

Our domain: sirius.pro

Thanks.

P.S. I can provide more detailed information about us if it will be necessary.

is there a "matching list" to compare local and global bad sender?

Hi all,

my question is about comparing my local bad sender list with the global list. I wonder if there is a tool that does it automatically and, once it finds a match, it will notice me so that I can "clean" my local list removing the already-blocked senders present in the global list of Symantec, avoiding redundancies.

Thanks for your help

This is the second time in the past two months that valid iCloud.com emails have been deleted with a verdict of "Symantec Global Bad Sender".

Furthermore, adding the email to the Local Good Senders List does not allow the emails through.  They still get Deleted.

Is there a resolution to this issue?

I see email come in from senders where it passes through Messagelabs and the subject is edited to read "Detected as Spam" before it hits my mail gateway.  Is this by design?  This is outgoing email and it's being tagged/edited before it hits me as the recipient.  I don't use MessageLabs so why does this happen?  Partial header information is added for review.

Hi,

Is there a way in SMG where domains that users already send emails to get white-listed? For example, if a user in our entity emails xxx@global.com, the reply or any future email from users at global.com should not be held in the spam quarantine.

Thanks.

How to combine actions between SPAM and Malware Policies?

I need a solution

Hi,

I've enabled the Malware PolicyContains attachment(s) supported by Disarm with two actions:

1 Hold message in Spam Quarantine

2. Send notification "Notify Users"

Also I have enabled the SPAM PolicyIf message is spam with the action:

1. Append subject line with " [SPAM]"

The problem comes where a e-mail is spam and also contains an MS Office (w/ malware) file because the user receives the notification and some of them tries to release the mail from quarantine.

Is there any way to "exclude" notification (action 2) if the e-mail has been detected as spam?

How to exclude policies between Reputation, Spam and Malware policies? (I don't have problems with Content)

Thanks!

Hi everyone,

we have a problem with out SMG. We cannot release any mail from quarantine.

When we chose release option, it seems that the mail goes out of quarantine queue, but it lost. It does not go anywhere and disappears. I try to find email in 'Message audit' but there is a status 'Hold message in Spam Quarantine, Released'. 

When I click on the recipient (in Message Audit), I review the section related to 'Delivery', It is displeyed IP address of SMG server, not IP address our Exchange server. End user dont receive mail. 

Two screenshots are in attachment.

Can someone help me with this issue ?
