Sorry for the reply at the wrong place. Using gmail because of this trouble. without the plain text checked. My fault...
Thank you for the help here it's moving along. Now, probably going to black list myself on gmail with all the test mails that got unleashed -face plam- I definitively had tunnel vision after 2 days. Now I'll continue. THe mails haven't shown up yet in my gmail account... Yes, it's a big network ;) and it's only one of the subnets ... Thank you again.
