Hello Stephan,

thank You for Your reply! If You need more information, just tell me how 
to get it - I'm not an email administrator, just trying to hold and 
serve my emails privately without needing to buy extra disk space from 
my provider.

To reproduce the abort, You'd probably need to fetch the original email 
- it's from the tomcat users mailing list (there're more than this one, 
but after this first fetching aborts):
