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

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.

Emails sent through my email address are received to client's spam folder

I am sending emails through my domain and it receives to spam folder of clients. Even I heard that email sent to gmail account are also received to spam folder.
I check with my hosting provider for all necessary configuration related to email sending are configured correctly. I am using dedicated IP, separate cpanel account, PTR and DMARC are set properly and enabled valid DKIM and SPF records for my domain.
I also tested the spaminess of the domain using a third-party online tool and the results were 10/10 which means they are fully authenticated.
Another thing I double check the content of the messages with spam tables. The content of the email should not look like SPAM.
Please help me with this issue.
Best regards,
Vijay

Google Apps - many of the emails sent from the server are going into people's spam boxes

We have bought the google apps account for the domain www.amarramesh.com hosted by bluehost.com
As per the google apps suggestion, we altered the CNAME records in bluehost for the domain www.amarramesh.com to sync with google apps.
There is an issue when I send the mail through a PHP file stored in my Bluehost server. I tested the email quality through mail-tester.com and it says the DKIM signature is not valid because in the DKIM signature selector = "default" and suggests I should change to "google.domainkey". Due to this, many of the emails sent from the server are going into people's spam boxes. How do I make this change? This problem doesn't happen when email is sent from Gmail.
I have tried Php-mailer and it worked for some time but Bluehost has now blocked it.
Why do you want to send mail from another host if you're using GoogleApps?
DKIM's purpose is to allow remote hosts to authenticate that your mail was really sent by the server(s) you permit to send them. This prevents a spammer from forging your domain name on spam he is sending out. If it wasn't bounced off of servers you authorized in your DKIM DNS record, remote mail servers won't deliver it -- or maybe send it to the spam folder (provided they look at the DKIM header and DNS record).
It does this by putting a private key encrypted header on the mail, and the public key to decrypt it on the DNS record. If it can be decrypted successfully, then it is assumed to be legit (because the sender knew the private key).
This might help if you want to enable mail being sent from both hosts.

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.

Sending emails from vendor's multiple domains

We have custom cms that currently sits on a vendor's subdomain, such as cms.vendor.com. It sends email out as coming from user#vendor.com and it seems to be working fine (using Email Queuing + SwiftMailer)
Our vendor asked us to put in the functionality for his users to be able to select from a dropdown, 3-4 other emails address associated with them from other domains he owns. Basically we need to be able to send out emails from our server labeled as being sent from #hisdomains.com, multiple domains.
I am a web programmer and have no clue when it comes to relaying messages. How would I go about being able to send out emails from his other domains? Does he need to setup permissions on his mail servers, or do I need to get into his SMTP servers to send out?
What are some things I should look out for when it comes to SPAM and gmail trusting us?
EDIT:
Not sure if my original question was clear enough. Vendor owns three domains: mysite.com, myothersite.com, mythirdsite.com. He wants a user from our crm to be able to send emails he has on those domains. So my dedicated server will be trying to send an email out as user#mysite.com, user#myothersite.com, and user#mythirdsite.com in the FROM: header.
As long as your server is allowed to send on behalf of a domain your vendor owns, you should not have a problem; just change the From: header to something else when you send out the e-mail.
Stuff like SPF, Sender ID and DKIM have to be properly configured to allow your server to send on behalf of any domain.
See also: http://en.wikipedia.org/wiki/E-mail_authentication
Any domain where the mx record resolves to the same server will work. so user#any.domain will email the same user on the mx contingent server.
To answer your question - just make sure that the mx records in the DNS zone file for each domain name points to the same server as the domain you want to share emails on.
also dependent on server configuration (like shared or whatever) I'm assuming it's dedicated with a simple email server installed. I'm not sure on cPanel/shared servers. but possibly the same.
