Re: Issue with POP3 and file attachments

Tech-Archive recommends: Fix windows errors by optimizing your registry

POP3 is doing the mime encoding. We have even tried using a custom pipeline and looking thru the message and that itself also does not get the original filename.

Hi,

So, is the POP3 adapter doing the MIME processing or are you using a receive pipeline with the MIME decode in place?

Thanks Joerg - but it's not missing, we are consuming around 8000 emails a week, around 45% of them Biztakl doesn't show the correct filename even though it's in the message.

On the web I've seen this issue mentioned a lot with no resolution.

Hi,

Maybe the filename is missing in the original mail? It is strictly speaking not mandatory in a MIME multipart element.

Hi

We have a biztalk orchestation and C# helper to retrive email via POP, store the attachments in a database, and forward the email to a different email address using SMTP.

Almost working great, except for no reason we can fathom the file attachment name will suddently be what looks like a GUID rather than a filename.

Here is a snippet of our C# code which is causing the issue. Partname usually contains the filename, but sometimes it doesn't!
Thanks
Paul


foreach (Microsoft.XLANGs.BaseTypes.XLANGPart xpart in x)
{
partName = xpart.Name;
partName = partName.ToUpper();

biztalkStream = (Stream)xpart.RetrieveAs(typeof(Stream));
