Block email with empty sender!

[Chai]

Anyone knows how to block these people? I noticed some people are using empty sender to send emails, because most email servers bypass filtering for these type of emails because delivery notifications don't contain sender's email.

This is very very annoying because none of my spam filters are able to block them!

Hmm.. This I would like to know too...

Hmm.. Even Bayesian filter not helping filter them out based on their content?

It's a legit email, but I want to block them.

Using Outlook? Then Set a rule to move. delete or mark as spam by checking on the sender field of the email if it matches "nothing"

Can't set empty sender field.

I use the 'check specific words in body' feature instead.

There is another way you can try....which tell u which e-mail server it from...

on the blank sender email right click-> Option->INternet header

It should tell you what you want i think

Hmm not sure if I can block the email server. I will try and see.

After i check i dun think we can block the server may be you need to look into the data and check out what you can find inside...

Hmnmm you're right. Hmmm let me search more and see

Edit:

Found this. not sure if it applies to outlook or not. underlined the specific step of using "" to denote empty field

Email Spam Filtering in Outlook Express:
If you're tired of receiving junk mail, you can have it deleted before you even have an
'opportunity' go read it in Outlook Express. Simply proceed as follows:
1) Open Outlook Express
2) Select Tools from the menu bar
3) Select Message Rules... then Blocked Senders List
4) In the resulting dialog box you will find 3 tabs: Mail Rules, News Rules and Blocked
Senders (the default). If you select Mail Rules, you can setup rules based upon
subject matter, sender name or message content and have mail that meets your
criteria moved to the folder of your choice - or deleted. We recommend setting up
rules that delete any mail containing the following:
a) a blank 'sender' field (put "" in the rules field)
b) subject that contains !, $, XX, offer, cheerleaders, etc.
c) exclude the addresses from known offending countries such as .cn, .ch,.ru, .es, .jp,
.dk
5) You can selectively block certain senders by bringing up their message,
right-clicking on the senders address and selecting Block Sender... from the resulting
menu.
In addition, to permanently get rid of this debris, you need to empty your Deleted
Items folder periodically. To do this automatically, select Tools... Options, then click
the Maintenance tab and check the Empty messages from the 'Deleted Items' folder
on exit box, then click OK.
