Contact Form 7 does not send to To: address but does send to Bcc - contact-form-7

I'm using Contact Form 7 with WordPress.
When I send a form I get a success message (‘Message has been sent’) but the message never arrives at the email address specified in the To: field.
However, strangely, the email does arrive at the Bcc. email address.
Server email logs show the following errors:
550-Verification failed for wpress#mydomain.com
550-5.1.1 The email account that you tried to reach does not exist. Please try\n550-550-5.1.1 double-checking the recipient's email address for typos
I have checked this and recipient email does exist and there are no typos.
Hoping someone can help me.

Verification email not received by domains using Office365 email client

When someone signs up they receive an email with a link they need to click to verify their email. The email comes from no_reply#domain.com
So far all clients receive this email with the exception of clients using their own domain with Office365. With these clients it's not an issue of emails going to spam - they don't receive anything at all in either their spam or their inbox.
The email is sent from a domain that uses Google Business for email.
Any ideas how to solve this issue?
I should add that if the email is forwarded manually, it does come through, just not when automatically sent.

Sending mail by CDO success only if there are two recipients

I use CDO to send emails for years and since last month there is a strange behaviour when the recipient is yahoo. I get an error:
554 5.7.1 : Data command rejected: SMTP authentication is required for Yahoo mail delivery
However, if I enter TWO recipients separated by comma (even the same address twice), there is no problem and the mail goes ok!!!
Has anybody faced such a problem? It's crazy, isn't it?
Well it seems yahoo has introduced a new security check and do does not accept email from unauthenticated senders of any domain (my case).
So If I enter my email smtp password to send email, there is no problem at all.
Please note that I don't hav a yahoo account, my email is #otenet.gr (which permits unathenticated send mail).
PS
However, the security chek is easily bypassed by just having TWO recipients...

Receiving Email with any E-mail Address

I am aware about spoofing and it is possible to send an E-mail using any address you wanted.
My question is: Is it possible to receive an E-mail using any address you want?
Example: I received an E-mail from iamhimATprivatedomainDOTcom, that has been spoofed. Is it possible to reply to the address and the person who is trying to spoof me, received the E-mail even though privatedomainDOTcom is a private email server?

Joomla 2.5 emails not received

I have a joomla 2.5 website that has a 3rd party extension to send a contact form.
The contact form has three email address' set up as recipients, two of them are the same as the domain ( www.domain.co.uk and info#domain.co.uk ) and the other is my email address.
I receive the email with the completed contact form however the other two address' don't receive anything.
Before I migrated this site I had the same problem, the current working email address didnt receive anything but others did. Again before site migration the domain and email address were the same.
The client has checked there junk/spam folder and the email address is currently receiving other emails.
I haven't tried SMTP yet as I would have to get the info from a client.
Any other suggestions? Do you think SMTP would resolve the issue?
It is mail configuration on server - many times it´s sends mails without smtp credentials to "self domain" or domains housted in same server, but not outside.
Yes smtp configuration has to resolve this issue.

Is there any technical difference between To and CC field in Email?

I Know the below things
To: is to the person who is receiving the email or taking action regarding email received
CC: is "Carbon Copy" which basically is for information so that they know the "To" person recieved the email and the action should be taken on the mail received
BCC: Blind Carbon Copy meaning that the others who recieved the email will not know that the BCC person got the email.
But My actual doubt is that,
Yahoo is blocking the mails received by there user, send using third party tools/servers. Here is more info from Yahoo
When a send a mail from some site in the below format
From: xxx#yahoo.com
To : yyy#yahoo.com
Sender is receiving error message.
But if i send in below format yahoo is accepting mails
Edit
From: xxx#yahoo.com
To : zzz#gmail.com
CC : yyy#yahoo.com
The error you mention is purely caused by a policy with Yahoo that states, from the link you give,
Your message wasn't delivered because Yahoo was unable to verify that
it came from a legitimate email sender.
So Yahoo's concern is to make sure spam is not sent using forged addresses unknowingly to the legitimate address owner.
If you include the CC field with the same address as From, it means at least the "maybe forged" sender is receiving a copy of the sent email. And that seems to be sufficient for Yahoo to accept to forward your email.
