JavaMail - Managing undeliverable feedback, notification

[himgi]

Hi to all,
I'd like to know how to catch the unliverable messages.

I'm sending email through my class below, but I cannot catch if a
message is not arrived, if the email is wrong and if the receiver has
received my message.
I could I catch all these things?
Where do I find a complete list headers for JavaMail?

Thanks in advance, Himgi.

Hi to all,
I'd like to know how to catch the unliverable messages.

You can't. JavaMail just hands the message over to the local MTA. The
MTA is responsible for delivering the mail.

Where do I find a complete list headers for JavaMail?

There are no specific headers for JavaMail. You can put anything in the
headers you want.

See this list of common headers:

http://www.faqs.org/rfcs/rfc2076.html

Thanks for your answer!

How could I implent such logic?

There are no specific headers for JavaMail. You can put anything in the
headers you want

to get an idea of the sort of thing you might like to setup, look at
mail your standalone mailer sends or the headers from others.

I would really suggest not to work from examples, but from the RFCs.
There are just to many broken mail clients out there which are very bad
examples.

Looking at mail clients (more than one, non of these from Microsoft)
could maybe provide additional information, but is no substitute for the
standard.

My advice still stands. Examples help you understand what something
is for, what is in commonly use etc. Examples help sort out the
esoteric never-used stuff from the near mandatory. Then go read your
RFC. with that background and it will make a lot more sense.
