ISPC 2.2.33 Problems with vhost and send mails

[kings]

I realized Perfect Server Mandriva 2009 (64) as is in your description . Then I installed ISPConfig.2.2.33. Now the server does the following errors:

1.After each new created server does not reflect changes in the http.conf immediately .Make only files Vhosts_ispconfig.conf with date a suffix of creation behind. I make by hands changes for this files to be work my server with new domains
2. mailboxes at each site will not send mail on behalf of user@domain.tld but only by the server name - server1.example.com.
3. From e-mail client is not possible to send mail to other accounts from this user@.domain.tld.

I read many post in forums but I can't find real explanation of my problems.
Can you tell me where is the shuffle, so I can fix these errors?

2) You have to set the sender email address under options in your email client.
3) Look in the mail log to get the exact error message.
