There was quite a lot of good debugging info posted... Would it make sense for it to make it into the wiki?

Hi Glenn,

I just uninstalled two different versions of SpamAssassin and installed the actual version 3.3.1 from source. But the problem still exists after this.

This did the trick to me :-) "MailScanner --debug --debug-sa" gave me the hint:

11:33:45 Use of uninitialized value in numeric ge (>=) at /usr/lib/perl5/5.8.3/x86_64-linux-thread-multi/DB_File.pm line 276.
11:33:45 Use of uninitialized value in numeric gt (>) at /usr/lib/perl5/5.8.3/x86_64-linux-thread-multi/DB_File.pm line 280.
11:33:45 Deep recursion on subroutine "DB_File::AUTOLOAD" at /usr/lib/perl5/5.8.3/x86_64-linux-thread-multi/DB_File.pm line 235.

So there is a problem with the subroutine "DB_File::AUTOLOAD". I tested some things about DB_File::AUTOLOAD and after having a look at


I uninstalled "DB_File" (and I had also the chance to work with CPANPLUS
;-) ) and installed it completly clean and new. Some testing and: It works fine again! :-)

So a big "Thank You" to you Glenn, Martin and Steve for the hints. And @all on this list: I wish you a Happy New Year.
