Inquiry on javax.mail.SendFailedException: Invalid Addresses error

Hi,
Anyone does have any idea why the following is being encountered during the email authentication process? We are using PeopleSoft application and we have notification functionality which will send a notification email to the users but email not being sent due to an invalid email address but actually the email is active and valid. Below are the logs from SMTP
Log Start:

Kindly let us know your thoughts on this.
Thanks.

This isn't an authentication problem. You're sending to an address that your server doesn't know about, so it's rejecting your message. The error from the server is:
550 5.1.1 User unknown

Error: javax.mail.SendFailedException

Hi all,
I have a requirement to send a mail on click of a button. I have written a simple java code using java mail API. But while running the application i am getting
javax.mail.SendFailedException: Sending failed; nested exception is: javax.mail.SendFailedException: Invalid Addresses; nested exception is: javax.mail.SendFailedException: 550 5.7.1 Unable to relay for [email protected]
If i run the java code as a standalone java application everything is fine. Only in webdynpro application i am getting the above mentioned error.
My question is do we have to configure any settings in the WAS. If so, can somebody give me a detailed answer how to do the configuration.
Thanks and Regards,
Rathna

I stopped the Antivirus service and checked the application but it doesn't help.
Here is the code. But the code is working fine.

Is there any rule defined on the mailserver that BPEL is accessing via SMTP? Is it directly checking the address for validation or something?
Can you do a SMTP transaction on the BPEL server for this mail account only?
1) Create a notification process that sends a mail only for this user.
2) open a telnet session from the BPEL server commandline to do a SMTP conference.

Can someone tell me what I am doing wrong here?
Thanks.

The important line in the stack trace is
javax.mail.SendFailedException: 550 5.7.1 <[email protected]>... Relaying denied
The 550 error is being returned by the SMTP server to the your client as per the RFC.. It tells us that the client has built a message and has pushed it to the server. The server is looking at the message and finds something it doesn't like. It then returns the 500 series error to the client.
The relative locations of the server and client may be an issue since you can configure your server to treat clients run locally different, usually you have the localhost unrestricted and put the filters on for everyone else (there are some admins that lock down local clients on the theory that no one should be running a client on the server so if someone tries they must have hacked the box).
If you try running a different client on the machine with the identical settings for all the header fields you will still get the 550 error. At this point I would have a talk with the admin and ask what the rules for the server are.

What it means?
javax.mail.SendFailedException: Invalid Addresses; nested exception is: class com.sun.mail.smtp.SMTPAddressFailedException: 553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)
I use javax.mail API to send email from java servlet using a .info smtp server.
It is the domain .info that create this error?
Can i resolve?
I tryed with a .it smtp server but it doesn't change...only with the server smtp of my ISP the mail was send correctly!
Sorry for my english...Help Me!

The SMTP server you use does not allow relaying mesages from/to the specified domain. Example: you cannot use yahoo's SMTP server to relay an email to [email protected] Change your rcpthosts on the SMTP server.

Javax.mail.SendFailedException: 550 5.7.1

While trying to insert technician details into the DB, I get the following error. In the details I am entering an email id to which an email should be sent describing the details. The error is below :
Error: Error while Inserting Technician Details.Sending failed; nested exception is: javax.mail.SendFailedException: Invalid Addresses; nested exception is: javax.mail.SendFailedException: 550 5.7.1 Unable to relay for [email protected]
Could anyone please suggest a solution ?.
Your answers would be rewarded!!
Thanks,
Padmarajan

Hi Padmarajan,
Can you try this first from your Portal server ...
telnet smtpserverip 25
if you can connect then try sending a dummy mail to the same id as mentioned below.
This will help to verify if the problem exists at Portal level or SMTP server

Javax.mail.SendFailedException: Recipient unknown

Hi,
I know similar topics have been posted before but even after going through them all I have still not found a solution.
I am trying to send alert emails through my JavaMail application and get the Exception below. I am able to send emails to internal address', but not external address' such as my hotmail account. I have even asked the Administrator to put my IP address in the list of allowed IP's. Does anyone have any ideas? If anyone would like to take a look at the source code i have pasted it underneath the stacktrace.
Thanks in advance.

Sending mail to invalid addresses

Hello
I'm using TransportListener to catch TransportEvent, and my gmail account
My problem is that when i send a message to an invalid address, the event caught is MessageDelivered, ie, the mail is ever sent successfully, even when it is invalid, and i can't get unknown addresses.
message.addRecipient(Message.RecipientType.TO,
new InternetAddress("*[email protected]*")); // <- invalid address
