Small error with mail script on my website

[jorizzzz]

I've got a strange problem with a mail script on my website. This script is a contact form that emails me with questions from users. But since i've began using an external mail server, the emails aren't delivered any more. I've done the following things:

- Deleted my old mail accounts on the server
- Deleted the mx records
- set the mailserver (domain -> options -> mailserver) to external

If i'm checking my log files while sending an e-mail, it says that it deliveres it to www-data@YH-Linux01.mydomain.com instead of csd@mydomain.nl what i've entered in the mail form..

YH-Linux01.mydomain.nl is the hostname of my server...

Here is a piece of code of the mail form:

mail("$ContactWebsiteNaam <$ContactEmail>","$ContactOnderwerp","$Body","$Hoofd");

Where $ContactEmail is csd@mydomain.nl

How can i correct these problems? This is the message from my mail.log:

Jun  9 18:06:37 YH-Linux01 postfix/local[29337]: AC67F1D005B: to=<www-data@YH-Linux01.mydomain.nl>, relay=local, delay=0.07, delays=0.03/0/0/0.04, dsn=2.0.0, status=sent (delivered to command: procmail -a "$EXTENSION")

As you can see, it is not mailed to my domain but to the hostname of my server...

What's in /etc/postfix/main.cf and /etc/hosts? What's the output of

hostname -f

?

What's in /etc/postfix/local-host-names, /etc/mailname, and /etc/aliases?

Local-host-names:

localhost
YH-Linux01.mydomain.nl
localhost.YH-Linux01.mydomain.nl
localhost.mydomain.nl
localhost.localdomain
mydomain.nl

and ofcourse the domains of my clients

/etc/mailname:

YH-Linux01.mydomain.nl

/etc/aliases:

# Added by installer for initial user
root:   fred
clamav: root

The problem is that mydomain.nl is listed in /etc/postfix/local-host-names. Did you set the Co-Domain mydomain.nl to external mailserver as well in ISPConfig (go to Co-Domains, select mydomain.nl, and then go to the Options tab)?
