问题
I have tried so much and don't get things working.
I have a domain and no hosting/webmail so I wanted to redirect everything to my gmail account. As I have a linux (Lubuntu 13.06) machine running I thought I could configure a mail server. That seemed not to be so easy.
I have redirected my mail.domain.com to my ip and the port is open (I know this because while playing about, I once did receive an error message back by email from Postfix)
I am working with Postfix, however any other application is fine by me, if easier and just as safe.
I followed this instructions, however without success http://www.java-tutorial.ch/ubuntu/forward-all-incoming-email-to-single-address
All other instructions I read on the internet were alike.
When sending a test email (not from receiver address as this is a loopback issue with gmail) I do not receive a bounce and my log files are also empty so no clue what happens.

I've got it working now. For everyone who also wants a mail server just for forwarding mail:
nano /etc/postfix/main.cf
inet_protocols = ipv4
myhostname = mydomain.nl
virtual_alias_domains = mydomain.nl
virtual_alias_maps = hash:/etc/postfix/virtual
transport_maps = hash:/etc/postfix/transport
# catch all on your domain and send to gmail
nano /etc/postfix/virtual
@mydomain.nl mygmail@gmail.com
# transport all traffic to gmail through your isp smtp server
nano /etc/postfix/transport
gmail.com smtp:smtp.myisp.nl:25
postmap /etc/postfix/virtual
postmap /etc/postfix/transport
/etc/init.d/postfix restart
