Ok, if you are not using NFS for ANY part of the mail file system then you 
are best off using flock, add:

lock_method flock

To your sa-mimedefang.cf file

Also, see if perl is running in embedded mode, that might need to be 
adjusted, I do not know how well that behaves on Solaris so you might want to 
not run it embedded for testing as well.

If it is not being used, shut it off, this is something that should be done 
to any services you are not using and is a first step in hardening your

I probably should have asked for what version of perl as DB_File is a 
standard module with Perl nowdays. That is a current verion of DB_File so 
probably a recent verision of perl, perl 5.8 preferably.

Yes, the automounter is evil simply because I see many people use it for 
things that really, if you have to use NFS at all, should have been 
permanently mounted anyway (like home dirs, log dirs and mail spools). But 
regardless, if it is not in use.. turn it off.
