[Mimedefang] random 451 4.3.2 Please try again later

[ADNET Ghislain]

Hi,

 I have some mail rejected by mimedefang but i cannot see why. I use it 
in the default config file just to do clamav scanning and spamassassin 
filtering and it works well (i have reject messages for spam and viruses 
in the logs so all is fine). Nevertheless i have from time to time a :

451 4.3.2 Please try again later

Error and i cannot see why or where does it comes from. I have put the 
logs of the milter to a more verbose level to have more informations but 
i do not have anything more than this:

i use :

# mimedefang -h
mimedefang version 2.52
# spamassassin -V
SpamAssassin version 3.0.4
  running on Perl version 5.8.4
# clamscan -V
ClamAV 0.86.2/1023/Mon Aug 15 22:15:08 2005


mimedefang files are the default apart from the bare minimum to make it 
work.

Any idea why this message appear?  Could it be a ressources problem ?
