Email with CERTAIN Attachments can not be rec'd

[rokerij]

We have a user that is attempting to send out an email with attachments. <Office XP Outlook>
The emails are never being received. I mean never, it's not like the attachments are stripped and the user receives a blank mail, the mail never shows up. There is nothing in the outbox, and the email with attachments show up in the 'Sent' box. So, I sent each attachment to an external email server (Hotmail) and of the four sent each with a different attachment only one made it. This is the same one that makes each time I ran this test to numerous email servers. All of the files are in the same location and of the same type. I can not find anything unusual or different about any of the three files that will not send. I am at a lost, any help would be appreciated. Thanks in advance.

What are the file extensions of the attachments of the mail that doesn't get through? What is the file extension of the attachment of the email that gets through? It could be that the intended recipients are blocking all "unsafe" level 1 attachments either through their spam filter or virus scanner (we blocke at both as a double layer of protection)

We use XWall as our spam filter and have all level 1 attachments blocked there. We have the action set to drop the message WITHOUT sending an NDR. In addition we block certain virus attachments at XWall too. I know Hotmail will not return an NDR for an email that could not be delivered because it was considered spam or a level 1 attachment. I don't know about other mail servers.

Cheers.

Thanks, shortly after I had posted this, I had figured it out. The naming of the files was causing the files to not get through. Probably due to the spam filters you had mentioned. She had placed periods in the names of the three files.

That would do it. Both our spam filter and antivirus would have dropped it as being an exploit since it would see it as having a double extention (i.e. document.may 21 04.doc).

Cheers.
