Java EE (Java Enterprise Edition) General Discussion

Hi. I am making an application that sends e-mails by using Java Mail API.

However, our school does not support and blocked SMTP server. (I need to use

this program in the school)

The only thing we have is exchange server. And I don't really know what to do

with exchange server. I have searched on this forum, and some people said that

we can use 'IMAP' provider to use exchange mail server. However from what I know, isn't IMAP for just receving mails?

Is there any way to send emails without using SMTP server? (Our school does

not support SMTP, POP and all other things and all the ports are blocked for security issue. And they are telling me that they

don't have IMAP too. ( I don't know they are correct. I just think... they don't know what they are doing. - -)

But yes we do have mail server in the school. However we can only check and send emails by logging in to our network. If I am correct, they are using exchange server for that. Is there any way to send e-mail in this circumstance?

Thank You.
