hi guys

I'm writing an application working with javamail, and I send the mail throgh a proxy server(CCProxy, you can search Google, find it) .

I have searched google to find a solution for that. eventually, i found a tips from one website.

Assumptions


(Sockets v4, v5)
proxy host : 192.168.155.1
proxy port : 1080



Normally, if you ask question like this. people like to answer you

  Properties props = System.getProperties();
         props.setProperty("proxySet","true");
         props.setProperty("ProxyHost","192.168.155.1");
         props.setProperty("ProxyPort","1080");
 

or set the HTTP proxy host and port

 Properties props = System.getProperties();
         props.setProperty("proxySet","true");
         props.setProperty("http.proxyHost","192.168.155.1");
         props.setProperty("http.proxyPort","808");

But above codes will not working with javamail.

well, what should you do,

here is the solution that you can send mail through a proxy server

---

   Properties p = System.getProperties();
         p.setProperty("proxySet","true");
         p.setProperty("socksProxyHost","192.168.155.1");
         p.setProperty("socksProxyPort","1080");

hi,kanweng ,your code has helped me a lot ,but if the proxy server requires username and password ,can you tell me what should I do?

 

 

when running GmailFetch,I got the message(my jdk version is 1.5.0):
Exception in thread "main" javax.mail.MessagingException: Connect failed;
nested exception is:
java.net.SocketException: Malformed reply from SOCKS server

you're a life saver...thanks so much for sharing your code.. :) God bless

 

 

hello, i tried the gmailsender piece of code. however i have an error
on this line:
getPasswordAuthentication() {
return new PasswordAuthentication(xxxxx@gmail.com, xxxxx);
}});
for the username bit- xxxx@gmail.com, i get an error:
"syntax error on token "@",.expected"
can someone tell me how to fix this?

 

 

hi, your code use a socks proxy,
but how to use a http proxy?
anybody knows?
thanks.

 

 

JavaMail uses mail protocols - SMTP, IMAP, POP.
These protocols are peers of HTTP. They don't layer
on top of HTTP. Thus, an HTTP proxy is of no use
with mail protocols.

SOCKS, on the other hand, works at a lower level than
all of these protocols.

 

 

do you know about http proxy CONNECT ?
i think this can do the tunnel, if i can pass socket object to javamail, it can work.
but i didn't find a way.

 

 

Your code's gr8 & thx for sharing it.

I tried ur send mail code on my proxy.

It works like a charm.

However, when I run it on a proxy client, I get the following:

There's a bug in the example code in SSLNOTES.txt.
There's a method missing. Search this

I've the same problem as jitendravedi.

However, when I use any other account without SSL transport, everything work fine. Any idea about this problem?

Thank!

 

 

Any help? :(

It look like a Java SE or JavaMail bug ....

 

 

The root exception is clearly coming from the
Java SE SSL code. You might want to try
asking for help in one of the Java SE forums.
You might also want to try some of the
debugging techniques described in SSLNOTES.txt.
