Email spoofing from OZHealth and DrOZNetwork Newsletter

I have my sites hosted with 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 server.


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.

relaying not permitted …

Thank you for contacting Namecheap support!

We have disabled sending any emails with the field 'FROM; containing email address on the domain that does not exist on the server.

We have taken these measures due to mass SPAM sending through forums, guestbooks, contact forms scripts on our servers.

Mail relaying is also prohibited.

You need to change your script's settings. In order for your scripts to work as intended, you need to set the 'FROM' field to an email

address that you have created under your account. So please be advised to use email address crated in cPanel -> email accounts to send mails FROM.

Please contact us for any additional inquiries.


My Question was:

A member of my E-Card Program (I have 11 members) can't send today a card to his friends

and I had in my inbox with you for this the messages 'relaying not permitted'.

I tested it and it is so, from:   I get the message

'relaying not permitted'

and from: ... my program can send.

What means all my ECard programs can't send a card with a ... From: ....@..
which you don't know? This isn't true?

Maybe that is the reason and explains perhaps in the last month really less have sent out a card and I had this messages in my inbox with you. What have I to do that my E-Card program is send out?
