Cannot send email to domain-based email addresses - email

I'm not an expert on DNS and MX configurations, so any help on this would be appreciated.
The problem is my website cannot send out emails to the domain-based email addresses.
website is www.example.com
website can send emails to *#gmail.com or any other email addresses
website cannot send emails to *#example.com (they just don't receive any emails)
The domain-based emails work fine when used regularly (not being sent out from the website)
Domain is registered with Network Solutions
Website is hosted with GoDaddy
Only www, #, and * A Records are set to point to GoDaddy
Everything else (including the MX Records) are remaining the way they were before
The emails used to work fine before we moved to GoDaddy

Contacted GoDaddy and they said they needed to turn off emails on our plan to fix this issue.

Could this be the issue

the emails sent from my email accounts on my domain reach spam

I have a small problem with a domain and that is that emails arrive to Spam and that the domain is new. I have checked the reputation of that domain and it has nothing out of the ordinary.
Information
I purchased a CLOUD VPS that runs CLOUDLINUX with static ips in a different provider than the one I acquired the domain. and I use WHM to manage my accounts. the emails are sent correctly, but they reach me in the SPAM tray. as additional information I just tried to send an email from the webmail tool offered by CPANEL from my account, and from here if they reach me in the inbox, but if I send from any email client like: (Outlook, Thunderbird) always I get to SPAM.
What could be the problem ?, Where should I start to review? Any help or collaboration is appreciated.
Check if your server's IP is listed in any RBL
This is a good tool for consult in multiples RBL: http://www.anti-abuse.org/multi-rbl-check
See if your reverse DNS or PTR is properly configured
In your apllication always send email by authenticating with SMTP.

Spam mails Joe-Job via Amazon AWS

since a few days our internal email info#ourdomain.com seems to go bananas and sends out emails to all sort of email addresses. Some of those emails bounce and we receive Mail Delivery Failed emails every minute.
Here is our setup:
Domain hosted at Germany's 1und1 provider
Nameserver configured on Amazon Route 53
MX server mx01.kundenserver.de and mx00.kundenserver.de
Rails application hosted on heroku
I called the support at 1und1 and they told me to set a SPF record which I did:
"v=spf1 a mx ~all"
after researching the topic via http://www.spf-record.de/
Unfortunately this did not resolve the problem.
Honestly I am cluesless now what to do to prevent this random email sending.
Our account could have been hacked but the password was already changed.
Any of your email account or script/code compromise can cause outgoing spam emails. If outgoing emails are originating from particular email account and you find large outgoing email account from particular email account, you should consider to reset the password of that email account immediately. Also, compromised email sending script/code can can cause outgoing spam.
If "from" email address on spam email is none of your existing account then "From" email address is getting authenticated from any of your existing email account for which you should inspect SMTP logs of mail server(you should have administrative access of mail server)
Mail server IP address should not be blacklisted,please check IP here :- http://mxtoolbox.com/blacklists.aspx
If IP address is blacklisted, you can request IP whitelist after you identify and fix the outgoing spam source as RBL keeps IP address blacklisted until they find the spamming activity relaxed.
SPF and PTR record should be correct so that email recipient server can trust the sender mail server.
Bounce back email and spam email header can help to identify the issue more preciously.
This happened to me before, I had a "refer a friend" feature on my website and someone use an automated script to send emails to a ton of people. My server wasn't comprised, it was just bad coding in the feature that I installed that allowed my mail server to send mail to different people on my behalf.
Since the email is coming from you, your SPF/DKIM will check out just fine.
So thing about all the points on your website that can send email and see if any of them can be compromised.
Also you'll want to do a blacklist scan, I use this service it does more then 200+ blacklist: https://www.unlocktheinbox.com/blacklist/bl/
Make sure you scan both your domain name and IP address. But before you take any action to remove yourself, you should wait 24 hours until after you fix the exploit on your system. Requesting removal and popping up again can get you permanently listed.

Sending emails from websites on shared hosting - what solutions do I have

I spent weeks on researching the net on wich solution should I use in order to correctly send emails from my websites hosted on shared hosting accounts, but the more I read - the more confused I get.
So this is my situation!
I have among others, an ecommerce website built on OpenCart, on a shared hosting account and a few email addresses in cPanel, like sales#mydomain.com, newsletter#mydomain.com, contact#mydomain.com, etc. These email accounts are also accessible via roundCube by the user at email.mydomain.com and via IMAP\SMTP on their email clients like Thunderbird.
The website has these email addresses set up and it uses (at leas Opencart does) php mail() to send emails for events (new order, contact, quote, etc).
Since last year or so, providers like Yahoo keeps banning the server's IP address and emails get bounced back with failure messages, Gmail recipients get them in Spam folder, etc. I almost monthly ask my hosting provider to change IP address, ask Yahoo or spam services to unblock the IP address, do tests, etc and I don't even have a large number of emails going, like 100 per month, most of them are Ask for a quote wich are plain text messages.
In other words, it isn't working.
What I am looking for what solution should I use to send emails from websites hosted on shared accounts, that is transactional emails and newsletter emails without upsetting Yahoo,Google,etc. subdomains? external smtp service? configure email accounts in a specific way? What do you guys use ?
If you are able to add extensions to Opencart on your shared host, you may want to consider adding the phpmailer extension (http://www.opencart.com/index.php?route=extension/extension/info&extension_id=3932). This will enable you to send all outgoing mail from Opencart via phpmailer, which can be setup to send mail through a remote SMTP relay (such as smtp.gmail.com, sendgrid, or some other remote SMTP relay). A reputable remote SMTP relay will probably be less likely to be blacklisted than your host's SMTP relay that the php mail() command is currently using.
