ppa upload went to black hole

Hi,

I'm quite new to ppa so sorry in advance if my question is futile...

Yesterday, I made a team account (and it's ppa) https://launchpad.net/~openplacos with a friend of mine. I follow instructions from tutorial:

create a gpg key
confirm key with email
sign conduct code

It seems I've done successfully all these steps. Then I try to construct and push my source file:
$ debuild -S -sa (this script ask for my gpg passphrase)
$ dput ppa:openplacos/ppa <on the generated .change file>

dput prints that upload is successfull. However, after one night, I've no email (confirmation/rejection), even in spam folder. Build page (https://launchpad.net/~openplacos/+archive/ppa/+builds?build_text=&build_state=all) is totally empty... I found no information on help page except if:
1. gpg key not verified (my key seems to be ok)
2. source not signed (already verified)

Do you have any suggestion ?
Thanks in advance,
