Strange spam e-mail with no return address or name

I received twice today a spam e-mail which had no "noticeable" content. There was no return address and no content. Does anyone know what might be causing this or what it might be?

The X-account key was:account4
XUDIL:279421D.CNM347779F9
X-Mozilla Status:0001
X-Mozilla Status2:00000000

The second time
The X-account key was:account4
XUDIL:7DC363.CNM34777BD9
X-Mozilla Status:0001
X-Mozilla Status2:00000000

Can't help..unless R2D2 has just become a TT member

Oh shit!

Did you try to highlight the content area?
I have gotten an email like that with nothing in it, and when I used the cursor to highlight the content area, words showed up, but they were all scrambled.

I get these from time to time and just delete. figure the content was a virus or somnething that has been quarantined by the firewall

Not really sure what you are asking. It looks like a mal-formed SPAM mail - junk it. Spammers use all manner of applications and mail routing to distribute to millions of addresses in one mailshot. They also take major steps to hide their original identity (which always seems ironic to me as at the end of the day, if you are going to buy the peppermint Viagra they advertise you are going to have to go back to the source of the ad). With so many millions of mails to send and so many people (the mail relays) now taking steps to inhibit SPAM mail transfer, the chances are high thart many mails will be incorrectly sent, or more likely mail headers or bodies will be messed up during their journey through the net, either by accident or on purpose, but still get though to an addressee. What you have are mauled mails... There is a slim chance they weren't SPAM but were mauled anyway - shit happens. In this case, simply hope they get re-sent...

Yes, but this was the first time I received something without any information. No person, no header no address. But they are deleted and hopefully I won't see anything else.

X-UIDL: This is a unique identifier used by the POP protocol for retrieving mail from a server. It is normally added between the recipient's mail server and the recipient's actual mail software; if mail arrives at the mail server with an X-UIDL: header, it is probably junk (there's no conceivable use for such a header, but for some unknown reason many spammers add one).

It usually forces mail to stay on a server, and allows remote access to have mails sent to a client, hence replies can earn money!!!

It's often used (especially by Mozilla) to identify mails already downloaded from a server, for those cases where mail is left on the server, and only new mails are donwloaded with each session. The UIDL is a unique identifier used to compare for new mails. Probably not relevant here in any case - as the other headers and body are empty anyway.

Thanks YL6, I was going to add it as a link, but since most was reproduced here ... messagelabs faq'...
