MailScanner flooding auth.log

[Arjan Schrijver]

Hi list,

Ever since we installed MailScanner 4.60.8.1, our auth.log has been 
flooded with su's from root to nobody.
A little investigation told us that MailScanner was su'ing to user 
nobody for every mail, just to execute 'hostname --fqdn'.
This is new in 4.60, since the old MailScanner installation didn't have 
the problem.
Why was this done this way, and isn't there a more clean way to do it?

Regards,
Arjan
