[Mimedefang] smfi_chgheader returned MI_FAILURE

[Mark London]

David - You are right, if I set the timeout to be at least 2 minutes, it 
does deliver the message after 1.5 minutes of solid 100% cpu usage by 
mimedefang.pl    A solution, albeit not a great one. :)  If I remove the 
call to action_change_header in my script that adds the Spamassassin 
header, the message gets delivered also immediately.  So for some 
reason, a very long Preferences header take up a huge amount of cpu, at 
least in my situation (p.s. I also tried upgrading to the latest version 
available via the rpm, which is 2.61) - Mark
