Good afternoon.
I have the following issue
When I send from example#gmail.com to other gmails or company mails working properly.
But when I try from example#gmail.com to send to example#company.com I receive the following error
550 "JunkMail rejected - mail-yb1-f181.google.com [209.85.219.181]:40242 is in an RBL: "
If I send from another example_1#gmail.com to example#company.com working properly.
I check if the Ip is blacklisted but is not.
What I should try? Please help
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
I'm trying to send emails via Javamail to a corporate account. My Java test app works fine when I send message to gmail and my personal email. I can also successfully send to the corporate account via my email hosting webmail client.
I've read through posts here and have tried setting -Djava.net.preferIPv4Stack=true in the VM for the test app but it did not work.
I have checked the junk mail at the corporate client and the message is not there. That is not to say its not being blocked elsewhere at the corporate site.
Any ideas what can be causing this problem?
I'm using org.apache.commons.mail.HmtlEmail and this is the test code:
// Create the email message
HtmlEmail email = new HtmlEmail();
email.setHostName(smtpHost);
email.setAuthenticator(new DefaultAuthenticator(smtpUser, smtpPwd));
email.setSSLOnConnect(true);
email.addTo(to);
email.setFrom(from);
email.setSubject(subject);
// set the html message
email.setHtmlMsg(text);
// set the alternative message
email.setTextMsg("Your email client does not support HTML messages");
// send the email
email.send();
So #Bill's question regarding Javamail debug output got me thinking about the content of the email message. The debug log shows all is fine but what I found was I included Bootstrap and Fontawsome JS / CSS links in the email header and that caused the message to be rejected by the corporate system for security reasons presumably. Thanks for the help
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 use SwiftMailer for send mail to facebook user. Sometimes I get response from facebook mail server
said: 554 5.7.1 POL-P8 http://postmaster.facebook.com/response_codes?#pol-m Message refused (in reply to end of DATA command))
Please tell me what could be wrong?
I'm not sure, but this could be a result from a non-valid or non-existing SPF record for the domain name.
