Yahoo mail killing my attachments?

[elkinm]

I tried sending myself a file from work but when I tried opining it in Outlook Express, I have no attachment. Just the email body itself. Then I logged into yahoo mail and tried downloading. The file size shows the proper 3 MB but it tells me that this file type cannot be scanned for viruses and when I try downloading it I get a 1kb useless name file.

This is driving me nuts, I remember when I once tried sending an exe to someone who needed it with hotmail and some other services and they were removed regardless but here a regular unknown file (to yahoo) is removed.

How can I get the file and stop absolutely any and all file deletions from my yahoo accounts. There have been many cases when I failed to get a file from myself or someone else and this is getting insane.

Thanks

Just for the hell of it, I tried forwarding the email to my hotmail account and fortunately I managed to successfully download the attachment. The problem it that it is Winmail.dat with is ads a new level of horror to this issue.

I read that winmail.dat is a specialty Outlook TNEF format, and unfortunately I do use Outlook at work which personally gives me a whole new level of hat towards Outlook.

Assuming the file is intact, is there any way to extract the file I need from the .dat file without having Outlook. And either way, why did it send a .dat file as it did not before and can I configure Outlook at work to not send these dat files but the actual attachment.

Thanks again.

I found instructions on how to get the file from the .dat file here. And it worked.

So it seems that Yahoo may not be at fault here but I still could not get the dat file that I downloaded fine from hotmail.

But I sometimes do lose files through email. When I try zipping the file the zipped file comes empty and if I zip or compress with another format and/or change the file extension the file becomes corrupt. Is there to get around this supposed security or are we stuck.
