Misconfigured auto-responders.

Abuse reports have been filed with the Taiwan ISP that is sending the
bogus virus alerts spoofing the SAMBA.ORG domain as a sender.
They are also being filed with the domain that is issuing challenges to
the mailing list.
Eventually the spamfilter will learn to identify them and issue SMTP
rejects back to the sender.
In my last post, I got two out of office responders.
An out of office responder for e-mail or voicemail is the on-line
equivalent to a pile of newspapers on your front door.
They should not be ever be sent to unknown recipients.
In television interviews, convicted criminals have testified that they
have used them to get information to steal from companies.
These thefts have included getting company secrets or physical property
mailed to them, including one of a kind prototypes, or convincing the
company that the person out of the office authorized the payment for
something.
Please do not send me e-mail asking if it was your auto-responder, just
check your settings, and make sure that it can not deliver out side of
your company or to a select list of people.
Most corporate e-mail systems allow assigning a secondary user to
monitor the business e-mail while you are on vacation.
Also many anti-spam lists are spamtrap driven, and viruses / spam are
sending using the e-mail addresses of spamtraps. An out of office
message sent to one of them can cause your mail server to be listed in a
spam blocking list.
A spamtrap is an e-mail address that is hidden on a web site, but never
used to send a real e-mail, so it should never receive any.
