Remote Mail Problem

Hello,
after trying out for 2 days, I finally have to ask you.
First, there seems to be a bug. When you choose imap and port 993 you'll get no Server Access. Same with Pop and 995. But if you choose pop service with imap setting, it gets the access. It seems, that the template shows the wrong service. This kind of bug, you only find deep in the night after trying out everything else ...;-)

So I am able to get a test connection with the wrong service type: OK Gimap ready for requests from 46.163.74.4 r2if1011812eeo.109

The cron is: /bin/wget -O /dev/null "http://test4.autoundsport.net/index.php?option=com_easyblog&task=cron";
It seems to work, the controlmail says: connected, awaiting respone, saving to `/dev/null

When I put the task in the browser manually, I get the following statement:
Email batch process finished.

Mailbox: Could not connect to mailbox.

There, the problem seems to be ...
