The new attachment filter quarantines 100% of non infected zip files but for some reason some of the mydoom infected zip files go thru. This is what I put in to block: *.zip I'm running the beta 2.0.0.282 on a win 2k server. |

AJ, SpamFilter won't recursively check attachments in messages within messages. That could be one reasons some emails make it thru. If you send us an email to support@logsat.com with the infected email you received as an attachment we may be able to take a second look. Roberto F. |

AJ, Are you sure the zip came through Spamfilter and not direct to our email server ? I have found that everyonce and I will another email server will send mail directly to my mail server Check the message header and make sure it didn't bypass SF and come in directly to your mail server. Lee |

Lee & AJ, If you put a block in your router, allowing SMTP ONLY from your valid clients (the ones allowed to mail through you) then the only way a virus hit that server directly, bypassing the spam filter, is if your client has the virus. For us, as it turns out, the server that our clients actually use as an SMTP server in their mail client settings is, in fact, our Anti Virus server. That way, our clients can not add to the mess that Virusus like MyDoom is causing. Below is a small part of our porder routers access list. If you have a firewall, you can do the same thing. remark *** Next entries for allowing SMTP Regards, Dan S. |
