so which file are you actually looking for? It says "FileNotFoundException"; the name of the Exception tell the story. Either the file is in the wrong location, or it is already locked by another application.

The output shows that the connection to the server is successfully made - you may want to ask the mail server admin about this, as the error message doesn't give you a lot to work with.

That's a common JavaMail message; the file is not actually needed and its absence causes no problems.

That's a red herring; it's in the DEBUG output of JavaMail so it can't be that important.

Doing a quick search for smtp 451 I found this link which says
SMTP Error - 451

Requested action aborted: error in processing


This response is sent when the SMTP server incurred an error in processing an SMTP transaction

This PDF file has even more information:
SMTP Error 451 : The action has been aborted by the ISP's server. "Local" (Local Problem, Local Error) refers to the next server that your message will go through after leaving your server, typically your ISP's server, or the SMTP relaying service you are using, or, if your mail server is sending directly to the destinations, the destination mail server. This error is usually due to overloading at your ISP or your SMTP relaying service from [temporarily] too many messages or some other similar transient failure. Typically some [hopefully] temporary event prevents the successful sending of the message. The next attempt to send by your server may prove successful.

If this error keeps occurring to the point that it has effectively lost its transient nature and has become ..... frequent (!!), then the problem is at your end and you should check your own mail server (if you email out of a corporate network), communications on your side (router, server network card), or inform your ISP if your mail server relays through your ISP or if you are a home user emailing out through Outlook, Outlook Express, Windows Mail, or similar email program.

Examples of typical SMTP Error 451 return messages :
"SMTP error 451 Unable to complete command, DNS not available or timed out" or "451 Domain of sender address does not resolve" or "451 Error getting LDAP results in map", or "451 4.7.1 Greylisting in action, please come back in 00:02:00 [minutes]" or "The message that you sent has been delayed. The reason given for the delay : 451 Temporary local problem - please try later.".

------------------------------

With the original SMTP standards having been invented before spam became the scourge of the Internet, there are no SMTP error codes dedicated to anti-spam errors. As a result, SMTP Error 451 is now increasingly also used to indicate that a message has been rejected by the remote server because of anti-spam measures. A typical error might be, for example : "SMTP error from remote mail server after end of data, host <host_address>: 451 <ip_address> has recently sent spam. If you are not a spammer, please try later.".

If all anti-spam related SMTP 451 errors are as descriptive as the one above, then the error itself will tell you what you need to do. As a general rule, however, you will most times need to take some measures to have either your server, or your ISP's server, taken off some Internet blacklist used by the recipient.

Question too difficult for "beginning". Moving thread.

And thank you for pointing out my mistake.

And now for the actual movement
Other JSE / JEE APIs is where we usually discuss JavaMail so I'll move it there for you.
 
It is sorta covered in the JavaRanch Style Guide.
