Just wondering if there is any way to change the mail subject "Undelivered Mail Returned to Sender" to something else, if the error code is 550.
If no then is there is any way to detect a correct email.I am not saying about the email validation.That part is ok.But sometimes if there is no mail box then we get 550 error code.
Thanks,
SMTP reply code 550 means:
The requested command failed because the user's mailbox was
unavailable (for example because it was not found, or because the
command was rejected for policy reasons).
Double check your email settings.
On the other hand, the default error reporting email subject is fixed and you cannot be changed, as it is set in remote email server.

I got this bounce back email whenever try to send to a specific sender..
Any help would be appreciate..Thanks :D
mail content:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
example#example.com.mm
No Such User Here
Reporting-MTA: dns; mail.example.net
Action: failed
Final-Recipient: rfc822;example#example.com.mm
Status: 5.0.0
Unless there is something odd going on, the bounce back message is clearly telling you that the email address "example#example.com.mm" doe not exist. Perhaps "No Such User Here" is not the best wording, but it means that the email address is non-existant.
Is the .mm at the end of the email address part of the problem? Are you actually sending email to Myanmar?
I have never seen this bounceback message when the email address actually existed. Since this is unusual, I would send the email headers to the ISP of the intended recipient, since it is highly likely that is where the problem exists, and ask them to investigate. Also, I do think that you can get the same message if the users Inbox is full. Ask the intended recipient about that.
the problem has to do with your websites DKIM and SPF keys (Email deliverability in CPanel), if they are not added to the server it cannot verify the authenticity of your email.
The best solution is to contact your server support or CPanel support to fix the issue. There is almost nothing you can do via programming.
I had this issue and I spoke to my server's support team and it was fixed
At this point my email deliverability has not been marked as VALID, so the email
Mail delivery failed :returning message to sender kept persisting.
so I spoke to the server support team as the tooltip in the image suggested and it was finally fixed
if you noticed the VALID mark there
We are trying to figure out how to reduce the amount of bounces for our email platform and, one of the solutions we've found on the internet is to, via telnet, verify if the email exists.
So, for this example, we connect to the MX:
telnet alt4.aspmx.l.google.com 25
We start the communication:
helo hi
And, for every email we try (valid and invalid ones), we always receive the same response:
mail from: <fsafsaffsf#FasgagaoaSFasfas.co>
250 2.1.0 OK d8si998940wrc.143 - gsmtp
Are they doing this to prevent maybe a possible listing of valid emails?
What is the best way to verify if an email is valid before sending an email to it? We need this because our clients often uploads a spreadsheet with customer emails and always one or two of them are mistyped.
Thanks.
For a given recipient email address, you can:
extract its domain name (everything after #)
query DNS for the MX record(s) of that domain
for each specified server, connect and issue a VRFY command (see RFC 5321 Section 3.5), asking the server to verify the email address.
stop when you get a success reply.
However, SMTP servers are not required to implement VRFY. The simpler solution would be to just send the email normally, and then handle any errors from the RCPT TO command, and also handle the possibility that you simply can't always detect delivery errors in real time. If the email has to be relayed across servers, it might not fail on the server you use for sending, it may not fail until it is relayed to another server after you have already ended your SMTP session. In which case, the only way to detect delivery errors is to monitor your inbound mailbox for delivery failure emails being sent back to you.
The problem started suddenly. I have a problem that I can not solve when a random address send email to my domain martizi.com:
Technical details of permanent failure: Google tried to deliver your
message, but it was rejected by the server for the recipient domain
martizi.com by feedback-smtp.us-west-2.amazonses.com.
The error that the other server returned was: 550 Mailbox does not
exist!"
I use SES only to send email, just that. I want to be clear about the problem I'm having:
Use SES only to send email.
I have a corporate email that is provided by another company (here I can not receive the emails)
In my domain I have another MX address that is from the company email. Sometimes when someone tries to send email to some box # martizi.com, it returns with the error shown above.
I've seen a solution to this problem: Adding email from domains
SES panel> Domains> Mail From Domains> ...
After this he gives me an mx record to put in my domain, I put it, however it stays PENDING VERIFY and after 72 hours, it fails. I've done this twice and it does not check. Is this the solution?
TKS!
Either you are receiving email for martizi.com using SES, or you aren't.
You say that you aren't. This means you should not have this entry in DNS.
martizi.com. 3600 IN MX 10 feedback-smtp.us-west-2.amazonses.com.
With that entry, you're telling the world that feedback-smtp.us-west-2.amazonses.com. is one possible server (of several) that will accept incoming email addressed to martizi.com. That isn't the case, so the existence of this is a misconfiguration. Remove this entry.
I am having a problem where i get a bounce whenever i send a mail to my email address xxx#mydomain.com, from xxx#anyotherdomain.com. I tested this with about 10 of my email accounts and none of them work.
However I am able to receive mails from accounts like xxx#hotmail.com or xxx#gmail.com.
I get this bounce :
This message was created automatically by mail delivery software.

failed:
However no error codes. If anyone can help me or point me at the right direction that would be appreciated.
You should see a more detailed error message below what you quoted. But I would check to see if you have an SPF record for either of the two domains and make sure it is set correctly.
This is bizarre. I am trying to send an email containing this link:
http://newslamp.com/post/158516/home-made-robot-doing-a-perfect-quadruple-backflip
This is going out through my ISP (RCN), to stmp.rcn.com. I live in the Boston area, but I'm emailing from British Columbia, Canada, using the OS X mail client. When I try sending, the error message says:
Sending the message content to the server failed.
Select a different outgoing mail server from the list below
or click Try Later to leave the message in your Outbox until
it can be sent.
If I change the email message by adding text: fail
If I modify the url after the domain name: fail
If I change the "http" to "ahttp" (for example): fail
If I remove "http://": fail
If I change the domain name: email goes out
It's not an intermittent problem -- I've tried this about seven times by now, and it is completely reproducible.
From Thunderbird running on Ubuntu 12.04, email goes out regardless of the domain name, but email containing the link to the correct domain name does not get delivered. Email with the incorrect domain name does get delivered.
What would explain this behavior? How can I figure out where the rejection is happening (mail client? mail server? Some server between here and there?)
Yes by the looks of this link http://www.dslreports.com/forum/r28323974-E-Mail-RCN-Spam-Mail-filter- rcn has a very aggressive spam filtering system so you would be better turning this off or configuring your mx records and using your servers mail system
