It appears that jadechip.com is in China, using a chinese ISP for mail service. A great many system administrators reject all mail from chinese hosts as a spam prevention measure, as great oceans of spam have historically come from China. Korea usually gets similar treatment. I cannot say if that is what sourceforge.net is doing, but it looks like it might be the case, and you are caught up in the broad block.
I don't think that SF is blocking email on this level, and at least they claim that they send bounces in case of rejects; but there is at least one case of configuration problems where no such bounces seem to be sent - when your ISP does not accept bounce messages to the postmaster address.
To test:
-> telnet mail.domain.tld smtp Trying AAA.BBB.CCC.DDD... Connected to mail.domain.tld (AAA.BBB.CCC.DDD). Escape character is '^]'. 220 mail.domain.tld ESMTP HELO mail.denx.de 250 mail.domain.tld MAIL FROM:<> 250 ok RCPT TO:postmaster@domain.tld 553 sorry, we do not accept bounces to postmaster@domain.tld (#5.7.1) QUIT 221 mail.domain.tld Connection closed by foreign host. ->
If you have such a situation, your messages will be rejected by SF, and may or may not receive bounces.
