Default

in the file / etc / mysql / my.cnf I have add the following line:
max_connections = 500
max_user_connections = 500

in the file /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4

And after that there is no more error as before.

but after that it now

But when I try to send a test email sent but not entered in the Mail Inbox.

I try to telnet port 25 from the cmd very long response and then drop out:
220 test.dummy.example.net ESMTP (Network)
421 4.4.2 test.dummy.example.net Error: timeout exc

Connection to host lost.

C:\Documents and Settings\Administrator>


and very many activity from mail.log, in tail -f /var/log/mail.log
