Hello,

there was a problem on my old v5 installation that was really annoying, so I tryied to test v6RC1.

But it is still here : I can't send a mail.

Here are the log from zimbra.log :

So it seems that curl can't find the host mail.kawaiyume.net ???

I can solve the problem, with a zmcontrol stop/start, but some times after (can be few minutes, to 1 day) I still can't send a mail

Any idea ?
