| Hm, strange.... I'll have to test a bit .... But first I need get some

help to you:(
Well. It will not stop me from looking a bit further. (Please enjoy some
sweet dreams while you sleep.) So I picked up the source RPM for postfix
and started to grep for postmaster.
The following remark struck me as interresting:
~ * By default, Postfix probe messages have "postmaster@$myorigin" as the
~ sender address. This is SAFE because the Postfix SMTP server does not
~ reject mail for this address.
So I throw in the following line back into header check:
/^To:.*postmaster at vanderkooij.org/ HOLD
Now I need to sit back and wait .......
It looks we got ourself a winner here. The added header check works like
a charm. So it looks like we found an alternative to the HOLD everything
~ method. So I now need to sit down and describe the method in a bit more
details so other people can enjoy it too if they like.
