Is this a relation of a virus?

I've recently had several emails similar to this;

From microsoft delivery service [smtpengine@netmail.net]

To; Inet Recipient

Subject; undelivered message: returned to sender

Messgae; Undelivered message to grbmuozf@netmail.net

I have received some email with attachments containing viruses which AVG has quaratnined.

Need I be concerned?

 

For a second opinion to see if infected.

If you are concerned that you are in fact sending these out, you may not be. Someone else has you in their address book, and the virus is inserting your email address as the sender, so that the infected person never sees returned email and makes it just a bit harder to see where it came from.

 

If you did not send email to grbmuozf@netmail.net
(and it is NOT in your windows address book) - and
it is being returned to you as undeliverable, then it
is quite possible that some spam outfit is using your
email address as a spoofed return address.

If you did not send email to grbmuozf@netmail.net
(and IT IS in your windows address book) - then it
is possible that you have a virus/worm sending out
email (using one name in your address book to send
to other names in your address book - possibly with
some private files from your own computer.

Of course, if you don't use the windows address
book (and an email client other than Outlook or OE),
and have an (up to date, and turned on) virus checker,
and use plain text (instead of HTML) email, then a
virus/worm is not likely what's causing this.

 

I use Outlook 2003 and Outlook Contacts but this address is not in my address book - I doublechecked just now by running a search of contacts.

Incidentally these 'spoof' addresses are all different.

Sounds as if your first para is the answer. Is there anything I can do except to add each to the junk senders list?

 

One of our corporate email addresses is sometimes used
by spamers as a spoofed return address, and we get all kinds
of returned and/or rejected email - particularly from AOL.

We just filter all email from "postmaster@whatever.com "
or "mailer-daemon@whatever.com" or whoever's sending the
undeliverable notices, directly into the trash and unread.

This is a bit harsh, as there are some notices that may be
missed (other than those in regard to junk senders), but we
live with to remove many returns for mail we didn't send).

 

Indeed. I'll just do that. Thanks.
