iis smtp nntp: Hi,

Whenever I have Server 2003 running with the built in mail server, and
oddly
enough,certain attachments simply don't work. For example, an email with
a
JPEG will work, but an email with a PDF or DWG will never even make it
to my
inbox. Suffice it to say, this is annoying. I can't find any info on a
list
of file types or a feature to disable.

Any ideas?

Ok. I've done some more experimenting, and found that I can send any 0
byte file, irregardless of size. Some PDFs will work, some will not. It
appears to be based on file size. But that doens't make sense. The files
failing are all smaller than JPGs and things that work.


For example. I have an 800kb zip file. I send it as a zip file, the
message never gets received. If i rename it to a jpg, and send it, it
works.

Yes. And removing it fixed everything. Thanks.

Interesting that it would do that.

The problem is that I now need to find a way to disable NDRs. Before, I
was simply using CatchAll to dump everything into a folder that the smtp
service couldn't write to, so the mail simply vanished, without sending
the NDR.

Any thoughts on disabling NDRs?

Do you by any chance have the catchall.vbs script installed to enable a
catch all email account ?

This stopped some emails for us, just like you explain, some emails with
attachments were just blocked for no reason at all.

Report the issue to Alex Feinman:

http://isorecorder.alexfeinman.com/catchall.htm

I reported it myself a couple of weeks ago but he didn't seem to belive me
because the filter isn't even supposed to run on incoming messages, only
outgoing. The way it works is that it catches the ndr and then extracts the
attachment, then puts that attachment into the specified catch all account.

Shouldn't block anything, but it does.

I'm not aware of another way to block ndrs but I have reported it several
times to MS, maybe we'll see this in IIS7.

Take a look at Mail Enable, the standard version is free and the pro version
with webmail is really cheap compared to other solutions, www.mailenable.com
