spam without subject line and no message

[Govert J. Knopper]

Started receiving many of these messages each day at my company's address.
No subject line, empty message. Fake sender; fake recipient
(fakename@ourdomainname). X-recipient is the postmaster address in our
domain.

Any ideas on the deeper meaning of this "spam"? At first sight it is
useless to the spammer(s). Could they be testing something? I haven't found
a way yet to block this.

Thanks, Govert

Mailwasher filter for [does not contain regexp .]
IOW: If the field you want to filter (subject, from, sender etc.) does
not contain any character (blank) you mark it for deletion or whatever.

Maybe they just want to flood your mail server or client. Define a rule to reject/delete messages with blank subject headers.

I am a happy user of Mailwasher at home, but it is not an option here at
work. Must be something at the e-mailserver end. We are using Ubeblock but
that doesn't recognize these empty messages.

Thanks. I don't see any option to arrange this in the current filter, but
I'll ask the supplier.

Either that, or their program is broken. Not unheard of.

My ISP blocks all that cr&p for me. if yours doesn't, get a new ISP.

I am also receiving these email.
Does anyone have further information re the purpose?
Is it a method of confirming valid e mail addresses?

What filter are you using? A proxy? An e-mail client's rules?

 

[Govert J. Knopper]

FTGate mailserver and Ubeblock filter. I have already checked with
Floosietek and there is no option to block this type of "empty spam"

The don't let you define your own rules? If so, think of it reverse.
Delete all incoming emails except those with at least one alphanumeric
character in the Subject header. In Outlook, the rule would look like:

Apply this rule when the message arrives
Delete the message
Except if the Suject has "a" or "b" or ... or "z" or "0" or "1" or ...
"9"

Basically you delete/reject the msssage unless there is at least one
character in the Subject. You test for "a" thru "z" (and optionally for
"0" through "9"). A blank Subject won't have any so the message gets
deleted. A message like "$%%,&*!!!" is not likely anything anyone wants
to get so it, too, will get deleted.
