Seems pretty clear in the response you received. The message transfer agent, who's Internet address is mx3.imadiff.net flagged your email as having content that it determined was contraband for their system. You need to look at what you sent and figure it out ... maybe it had curse words in it, or it had an attachment that the filter didn't like. You could try contacting the recipient and asking them what their mail filter system looks for as contraband and then look at the message you sent to see if you can figure out why it got flagged. Then remove whatever that is and re-send it.

Currently, almost all mail sent from my server are all saved in receiver junk mail. I am thinking. Is it because my server is sending spam mail? I refer to this post How to check if server is sending out spam?. I can check all email sent from my server by entering this command.
cat /var/log/maillog | grep 'to=<[a-z0-9_\.-]\+#[\da-z\.-]\+\.[a-z\.]\{2,6\}>' -o
I did send a few email by myself but the above command doesn't list out anything. If I cat /var/log/maillog, below is what I got. Not sure how to read this.

Any suggestions to check spam mail? Thanks.
EDIT after fix DMARC, DKIM and SPF (They all pass) - Now gmail is ok but hotmail is NOT ok.
Did several tests

By default, on a cPanel server, emails are sent using EXIM. So the email log (for received and sent emails) is located at /var/log/exim_mainlog. There you can see detailed info about whatever emails were sent to or by your server.
A lot of factors can lead to your emails being delivered to junk. Just to name a few:
- your server's ip address is blacklisted (you can check it using tools like http://mxtoolbox.com/)
- you do not have a proper hostname defined for your server
- you do not have a proper reverse DNS for your server
- SPF and/or DKIM are not configured properly
Try sending an email from your server to a Gmail address for example, a Gmail address that you own. Then go to Gmail and even if the email landed on Junk, please check the email headers. There you get info about what checks have been made, what Spam score you got for your email and so on. That would be a good starting point for you to figure out why the sent emails land in Spam/Junk.
Since you have provided very little information, is hard to guess or provide a proper answer...
We have set up Odoo 8 as a multi-user helpdesk tool, which creates a new project issue for each incoming mail. Incoming and outgoing servers are configured correctly and system parameters are set to
mail.catchall.domain: company.tld
mail.catchall.alias: helpdesk
mail.bounce.alias: bounce
The problem now is that every time a user comments the mail thread to answer the original issue creator, a new mail is generated with header
FROM: [user]#company.tld
TO: [followers]
REPLY-TO: helpdesk#company.tld
Which is totally fine but leads to a sending failure due to our SMTP configuration. To get around this we want to achieve that all outgoing E-Mails are sent from the same specified address, like helpdesk#company.tld, no matter which user response to the thread.
How do we achieve this?
I had specific issue when I was working on Odoo 8 and I found fix but its not recommended action from developer view, because changing odoo source code is not recommended and changes can be lost.
So what I did was to change email from address to real email from address. Yes it's weird but that's how Odoo works. Odoo is always sending from one specific email address and changes email from to user email address, but if you will look at email carefully you will notice that real sender is always same.
The fix is changing this line
smtp_from = message['Return-Path']
to this line
smtp_from = tools.config.get('email_from')
in openerp/addons/base/ir/ir_mail_server.py file.
PS I don't like this solution.
I really dislike microsofts ui it is terrible
im trying to setup my node.js app to mail using hotmail but cant.
i have got so far using:
var hotmail=nodemailer.createTransport("SMTP",{service:'Hotmail','auth':{'user':' exampl#hotmail.com','pass':'MY-Normal-User-Pass'}});
I get the error:
Message sent: 250 2.6.0 <1383551761565.976a644a#Nodemailer> Queued mail for delivery
so tried my normal user pass and my email now says sent but also says its queued i think 250 is like 'you don't have permission' from what i have read on google...
and check this, my hotmail sent box shows each email i have tried to send but my client does not receive them?!
also I have sent using gmail fine!
var gmail=nodemailer.createTransport("SMTP",{service:'Gmail','auth':{'user':'example#gmail.com','pass':'ufufufufufur7yryed'}});
it was the two step verification on goole ! very easy!!
if(r.email.search('#hotmail')!==-1||r.email.search('#live')!==-1||r.email.search('#outlook')!==-1){
hotmail.sendMail({
subject:c+' update received...',
from:'example#hotmail.com',
to:r.email,
html: 'Click this <b>link</b> to veiw your update.'
},function(error,response){
if(error){console.log(error+'!!!!!!!!!!!!');socket.emit('email_send.err');}
else{console.log("Message sent: " + response.message);socket.emit('email_send.ok',{'result':'200:ok'});}});
}
else if(r.email.search('#gmail')!==-1||r.email.search('#')!==-1){
gmail.sendMail({
subject:c+' update received...',
from:'example#gmail.com',
to:r.email,
html: 'Click this <b>link</b> to veiw your update.'
},function(error,response){
if(error){console.log(error+'!!!!!!!!!!!!');socket.emit('email_send.err');}
else{console.log("Message sent: " + response.message);socket.emit('email_send.ok',{'result':'200:ok'});}});
}
});
why is (not so)hotmail showing me sent messages when it's sent only storing my messages in my sent folder?
Actually Message sent: 250 means that the message was accepted. Outgoing SMTP servers do not send mail instantly but through a queue - once previous messages in the queue are sent out, your message will be as well.
If the message does not reach recipients inbox it might have got lost in the way, for example might get marked as spam etc.
We are in the process of converting a batch job that processes our bounced emails that we send. We are switching from Redemption to EWS (just upgraded to Exchange 2010 from Exchange 2003). As you know bounced emails come in different forms. I have been able to work through all the test case emails i've got except for the ones that come in the form of:
Your message did not reach some or all of the intended recipients.
Subject: Hello
Sent: 4/01/2012 8:16 AM
The following recipient(s) cannot be reached:
hi#foo.com on 4/01/2012 8:19 AM
The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator.
smtp.mydomain.com #5.0.0 smtp; 5.3.0 - Other mail system problem 554-"delivery error: dd This user doesn't have a foo.com account (hi#foo.com) [-5] - mail.foo.com" (delivery attempts: 0)>
This is what is displayed in outlook. When i read the email with EWS the Body is empty. I need to look at the information above when i get the email with EWS. The emails have an attachment (which is the original email) though it doesn't look that way in outlook. I've tried to look at almost all the properties that comes back from EWS and have yet been able to find the text above. Redemption allow you to look at this info using ReportText. What we are specifically looking for is the email error delivery code. We do different things based on this code.
Edit: To be clearer the Body Property on my other test cases isn't empty. I'm loading the emails like:
Dim emailPset = New PropertySet(BasePropertySet.FirstClassProperties)
emailPset.RequestedBodyType = BodyType.Text
Dim f = EmailMessage.Bind(email.Service, email.Id, emailPset)
Update1: After some research it looks like i need to be able to read the Recipients table of the message in the PR_NDR_STATUS_CODE & PR_REPORT_TEXT fields. Still searching if there is a way to do this in EWS.
We were able to get enough info the
smtp.mydomain.com #5.0.0 smtp; 5.3.0 - Other mail system problem 554-"delivery error: dd This user doesn't have a foo.com account (hi#foo.com) [-5] - mail.foo.com" (delivery attempts: 0)>
part which is what we needed by telling the object to load the MIME content.
Definitely not the most straight forward API to use but hopefully we don't hit any more hickups.
We are sending hell lot of e-mails to our BREW devices ( in sprint network ) and after a while our mail server queues the messages and gets stuck. When we try to flush them, we get following from the server. Is there a solution to this problem? Is this error 452 from our mail server or sprint's mail server? How to tune up sendmail for faster e-mail processing?

This is called grey-listing. When you send too many e-mails (or more often - a certain number of e-mails where a recipient does not exist) a destination mail server does not black list you, but instead they temporarily block access from your mail server (essentially the IP address of your mail server). Usually this block is set for 1 hour but obviously can vary depending on the configuration.
You can do several things:
Contact the admins of the domain in question (e.g. postmaster#messaging.sprintpcs.com) and request your IP address to be whitelisted. (They may refuse)
Check/increase time e-mails can stay in your local queues (to have more chances of them to retry and finally get delivered
Add more public IP addresses to your server
That's from their server. It looks like email flood prevention.
One alternative is to use app-directed SMS's to get data to your BREW application.
It looks like the mx.messaging.sprintpcs.com is throttling you. Perhaps try sending your mail with different IP addresses to beat this. It is probably an attempt at spam control.
