File Attachments sent to multiple recipients corrupted! 2

[dpazuk]

Hello All,

We are using Exchange 2000 on an MS 2000 Server box, Norton Anti-virus for Exchange and GFI Mailessentials with all of the latests service packs installed.

Problem: Files sent to mulitple recipients are showing up corrupted. I have re-installed the latest service pack for Exchange, but the problem persists.

The files do not show up corrupted internally, only those sent outside of our organization.

I ran across a Knowledge Base article from Microsoft (Article ID: 182307) regarding Exchange 5.0 and 5.5 and their use of Quoted-Printable encoding for text files and a hot-fix to add a registry key to force Base64 encoding.

However, I am running Exchange 2000 and can find no such articles involving this problem with Exchange 2000.

Can I force Exchange 2000 to send text attachements with Base64 encoding? (Assuming this is the problem)?

Any help you may be able to provide would be greatly appreciated.

Exchange 2000 does encode base64 for outgoing messages.

http://support.microsoft.com/default.aspx?scid=kb;en-us;323489.

I'd take a look at the message leaving exchange, then look at it again leaving your relay if you have one.

We are having the same problem. Unfortunately answers on the subject are few and far between. I did find something on the experts exchange forums that suggested upgrading to GFI ME11, we did, still having the problem.

It does, however, look as GFI is the common factor ?

I will probably be opening up a ticket with Microsoft on Monday, will keep you posted

Thanks All,

We too have the auto-disclaimer activated with GFI and we are using version 11 of their software.

I half suspected this to be the cause.

I will de-activate it and see if this helps solve the problem.

I have also posted on the GFI boards.

GFI have responded on the forum - basically set up some logging, and send the files to them when the problem has reoccured

Normally, they will analyse, then email you a bespoke patch
