PL\SQL is designed for processing data that is in Oracle databases.  Trying to use PL\SQL for something it was not designed to do may not be your best option.

I've never used the MAIL_CLIENT package, so I can't help you with that.

It may be easier for others to help you here if you describe the problem or error you see with the host name, and if you give us some information about: "Not connecting", like what exactly is not connecting to what?  Do you get an error message?

MAIL_CLIENT Contains Java Methods to Fetch the Data from Mail Server.
in that  we have a Method initially to connect/ Login to the Server from Back end.
  p_hostname => '',
  p_port     => 143,
  p_protocol => mail_client.protocol_imap,
  p_userid   => '',
  p_passwd   => '***',
  p_ssl      => false
Not Connecting:
We are getting errors as (Unknown Host name, Network Not Reachable, No Route To Host Exception)    So, that we are finding Other way to fetch the Data from Mail Server.

I assume you have confirmed the database server can talk to the mail server on that port and this isn't a simple network issue.

Did you follow the installation instructions and perform the dbms_java.grant_permission steps?

Depending on your version of Oracle, you might need to set some network ACLs: dbms_network_acl_admin.

Yes slightwv,  i granted the permissions and  i am trying this from admin User..

in between i tried in other way i.e.
build a Mail Server in Cloud instance.
in the Same instance i added Database, in that database i installed Mail_Clint Package and tried connecting.
with this scenario we solved the Unknown Host issue but we are facing Another issue i.e. "ORA-29532: Java call terminated by uncaught Java exception: javax.mail.AuthenticationFailedException: [PRIVACYREQUIRED] Plaintext authentication disallowed on non-secure (SSL/TLS) connections. " while running the Procedure Connect Server.

can you Explain me what Exactly we need to do to setup network ACLs: dbms_network_acl_admin.

>>Plaintext authentication disallowed on non-secure (SSL/TLS) connections.

In the connect_server call, I would take a look at:  p_ssl - SSL flag - defaults to false.  Possibly set it to "true"?

Sorry but I cannot provide exact steps you need to take because I don't have a system setup similar to yours to test.  I can look at the documentation you provided and errors you are receiving and make some guesses at what might be causing issues.

Thank you slightwv.

we tried that option Already but we need certificates for that. it checks the certificates at that time.
than we get another type of error like "No Certificates found.."
Pradeep komariSystem AnalystAuthor Commented:
we got the correct Solution from other source.
Actually the problem is located at Mail Server configuration in Linux.
we don't have the parameter "ssl" in configuration file.
we must declare that parameter as no for this type of error.

Thank you all.
