It is already installed, so this does not help me

Registration confirmation is turned on or off in Admin Panel/Setting/Moderation Settings.

You're are going to need some sort of MTA (Sendmail, Postfix) to send confirmation or any other emails or message notification from your domain.  You don't need to open port 25 if you are only sending mail out.  If you open port 25 so that you can receive mail on your domain, you will need to button down your system or it WILL become a SPAM relay.

Messages between accounts doesn't require an MTA, as it is not email

I am runing an Postfix email server!!! is there a file that I need to edit or something??????

Is postfix running?  If it is, there aren't any settings that you need to adjust (though you want to be very sure that you've locked it down properly so that it doesn't turn into a relay for Viagra.

If you have an email problem with the server in general, then I'd consider the following:

What flavor and version of Linux are you using?

Is Postfix your default MTA?  If it is, your IP and server name (mail.x.com) should be in entered in /etc/main.cf

A lot of Linux flavors install Sendmail by default.  You should be able to just yum install postfix -y and then make the server name and IP entries in /etc/main.cf and it should work right away, as long as it is the default mail program.

If you are not sure about any of this, then I'd do a yum system-switch-mail -y.  Then run the command system-switch-mail.  This program will tell you which is your default MTA, and allow you to switch to Postfix if Sendmail is the default.  The you can just erase Sendmail with an rpm -e sendmail --nodeps.

But if you have a working mail system, I don't see why you should have any trouble sending mails from Dolphin.  Then again, I'm not sitting in front of your machine.

Hope this helps.  But really, more information is needed to answer with any degree of certainty.

Make sure there is no restriction for mail function in your PHP settings.
