    	The latter remains to be seen. Originally I used 400,
    	but I found that it only led to massive and almost
    	endless retries for obviously bogus domains. Then I
    	switched to 500. And the loggings show that really
    	existing domains are hit only very rarely.
    Very rarely becomes 'quite a lot' if you have hundreds of thousands
    of emails a day. If 20 valid emails get bounced by us a day, that is
    unacceptable. We can not put the burden of this on our users, so we
    have to bear it ourselves by returning 400. This is partly of course
    a difference in the customers we serve :)
The latter is probably the deciding factor in which
approach to choose: an ISP is in quite a different
position than an end site.
