Exchange virus scan, spam and email security

By kipper_1 ·
Hi,

The company I work for had a major spam problem when I joined around a year ago. No spam solution was in place and the AV software had expired on the server.

I now use an external spam filtering service which deals with spam and virus before they enter the company. Fsecure is installed on the server and client machines.

Some spam gets through the system we use. A user noticed one of the spam messages they had recieved had also been sent to an email address which was in thier contacts?
The users mailbox is no longer backing up although I am unsure if the issue is related. I have posted the backup error message at the bottom of the post.

We often receive spam claiming to be from our company. Is this due to the email address being spoofed and is there a way to stop this?

The spam subject often looks like it is picking up information from somewhere as it is very accurate!

Are there any virus scanners I can use to specifically scan exchange or mailboxes for viruses as Fsecure does not find anything?

Fsecure recently removed an infected attachment from an email. On further investigation I noticed the email had not come through our external spam system which should process all emails. Our IT support company said our server had been telneted onto and the email with the attachment had passed through our hardware firewall and been removed by Fsecure for excange!
I tried setting up connection control on the default SMTP virtual server to only accept the IP addresses of our spam filtering service but this stopped laptop users being able to use Outlook Web Access.

Are there any settings I can use in in SBS 2003 to improve email security and spam.


Many thanks for your time,

Chris.

(( i have the same problem you got ,i got the answer for you ))

by mike1352002 In reply to Exchange virus scan, spam ...

after calling Symantec , they told me to disable Advance open file option. also they sent me an email , i will attche it to you..

It is not at all recommended to use AOFO on any Databases such as Exchange , SQL, Oracle , Since it will may back up well , but with the AOFO back up, while restoring you can?t do a redirect restore, or a restore to RSG
I am also sending you a technote which mentions if AOFO option used during the backup of exchange database it cant be redirected to RSG or any other machine. The other mentions that the Master database cant be redirected if Snapshot backup used,and not to use AOFO with databases.AOFO type Backup recommendation to use only particular agent to be used to backup particular database.
