Joomla 2.5 emails not received - email

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.

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.

How does an SMTP server resolve ambiguity?

Suppose I own an email 'demo#gmail.com'. Now, I create a new Microsoft account using my existing email. Thus I get another email 'demo#gmail.com', but this one is served by Microsoft.
So the situation is: one email and two providers.
If I send a hello email to 'demo#gmail.com' using my personal SMTP server, to which of the above will it send: will it send to the one hosted by Microsoft or the one hosted by Google?
How does it solve such an ambiguity? What are the factors that influence this?
This is a very common problem because many providers are giving us an option to create a new account using our existing email.
My observations:
I saw the emails inside the inboxes of both the services. I found that they had completely different emails.
There was no email which was common to both the inboxes. So there must be some mechanism to deal with it.
Let us look at the problem the other way round: If I had an email 'demo#outlook.com' initially and I created a new Google Account with this email address, then:
An email sent to this email address from another gmail account goes to the Google's server. An email sent to this email address from an Outlook also goes to the Google's servers.
There are two different ways of looking up an email. The 'normal' way:
You send an email to an server, in this example gmail.com.
Your mail delivery agent looks for mx record of gmail.comand send it to the ip-address of gmail.com.
If an email is delivered locally by the domain outlook.com it perhaps doesn't lookup the mx record, but lookups in a local database if the email-address exist there, and sends it to the ip-address of the outlook.com.
I think in the inbox of outlook.com are only microsoft emails.

Godaddy email forwarders not working when sending from php mail

I have an email forwarder set up on my GoDaddy account, which works fine when sending from an individual email account, but when I sent to it from a PHP script, it never gets received.
Here are a few additional details (I feel like the first two items here might be key in figuring out the answer):
The email forwarder is on a GoDaddy account with a domain name. The Website for this domain name is hosted on another godaddy account. The nameservers set on the Domain name account are the default name servers (The website is working properly, because both accounts are GoDaddy).
I have tried setting the email forwarder up on the hosting account instead of the domain name account. Interestingly, the email then does receive emails from php mail, but it does not receive emails sent directly from an email account. Instead, I get the error message "Your message wasn't delivered to name#xxx.com because the address couldn't be found, or is unable to receive mail."
I can successfully send an email to any other email account from the same php script, so the problem is not my php mail function
I had made some changes to MX records at one point, but then changed them back. A GoDaddy support tech said that they were correct and should work
I've spent lots of time with Godaddy support, they said that they can not help me since the email forwarder is "working" when sent from a regular email account.

Mailbox unavailable. The server response was: This domain is not hosted here

I am performing some tests on my Nopcommerce site that should allow the user to type a message in to the contact box of the site and that message should be sent by email to a user.
When setting up and testing said user on the site, I am able to perform an email test against an internal email address and this works fine, I receive the email. However, if I try and send the email to an external email address, such as hotmail etc, I receive no error logs at all.
Has anyone ever come across this issue when trying to set up an email on a Nopcommerce site?
I am using port 25 however I have tried to use port 587 with no luck
The answer was that the username and password no longer existed for the server I was sending mail from. Moreover, another issue I had was that the mail still wasn't sending and was sitting in the Message queue. To overcome this I had to make sure that the bindings for the site on IIS were identical to the host values on the site. Doing this allowed me to send mail.

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.
