I have my sites hosted with namecheap.com and since a while I have a high file usage, mails with unknown
addresses undelivered in my inbox and a high amount of cron-jobs with my blogs. This month was the amount
of undelivered mails so many, with addresses which not mine, that I have written a support ticket.
The most of this mails were sent from OZHealth and DrOZNetwork Newsletter with fictive addresses and
My host support means, this company spoof my domain:
E-mail spoofing is the forgery of an e-mail header so that the message appears to
have originated from someone or somewhere other than the actual source.
Distributors of spam often use spoofing in an attempt to get recipients to open,
and possibly even respond to, their solicitations.Unfortunately that is technical
realization of SMTP protocol, as well as settings of some mail sending systems, that allows
editing of headers of messages, for spoofing.
Spoofing is possibly the most frustrating abuse issue to deal with, simply because it
cannot be stopped. Spoofing is similar to hand-writing many letters, and signing someone else's
name to it. You can imagine how difficult that would be to trace.
I searched about this and found a lot of articles also a legal notice about spoofing:
Email Spoofing. Email spoofing is a serious computer crime with a likelihood of imprisonment.
Unfortunately because email spoofing is typically sophisticated, the government is likely to
arrest the innocent individual whose email address has been spoofed. Moreover, many attorneys do
not have the background and/or knowledge to successfully defend a person accused of email spoofing.
Someone accused of email spoofing needs the expertise of a strong computer crime defense attorney.
Email spoofing accusations fall under Email SPAM laws. (See table below.) A spoofed email may
appear to be from a lawful source, but it’s typically malicious in nature and contains defamatory
or damaging information, or it may ask for personal information, passwords, credit card numbers,
and other personal information, or it may offer a business proposition in which the sender offers
to pay a certain amount and sends a fraudulent check for many times the agreed upon amount with
the purpose of the receiver to send a refund with a lawful check in which the receiver has to
eventually reimburse the bank.
