Please help, thank you

im little bit frustrating now…i did work wiuth RT2 fine …then i did
install RT3 (complete new)
install was fine, i have all depencies web interface is ok… sendmail etc
is fine…but the mail never comes into the tracker…with
echo test | sendmail -bv
i see that he is going to the mailgate (rt)
how i can debug it cause logs (syslog/rtlog) does not have infos for me… is
there a debug info?
i use a https:// adresss is it not allowed?
when i make
echo test | /home/htdocs/rt3/bin/rt-mailgate --debug --url --action correspond
Connecting to at
/home/htdocs/rt3/bin/rt-mailgate line 473, <> chunk 1
what means this or is there a way to debug it?
