I've added 2contact.com to the /etc/hosts file. This is what my hosts file looks like right now:
127.0.0.1 phunix02 localhost.localdomain localhost localhost4 example.com 2contact.com
::1 phunix02 localhost6.localdomain6 localhost6
Also I don't think i'm blacklisted, unless the timeouts mean I'm blacklisted..
Listed 0 times with 4 timeouts.
But still nothing changed..
EDIT: there is another mailserver in the domain, could it be that's the reason why sending mail to gmail isn't working? The other mailserver has ip 10.0.0.12 and is also reachable at mail.2contact.com
This other mailserver runs microsoft exchange 2003, and when I check www.mijnip.nl
it shows me this IP: 184.108.40.206 and says my host name is: mail.2contact.com ... is there any way to fix this (if this ofcource is the problem) and could this also be the problem why mailing to the email@example.com
