ESMTP ABORTING: Connection broken during DATA

[Carsten]

Hello,

i am using amavis with postfix by sending mails to amavis via 
smtpd_proxy_filter.

But amavis runs in a timeout, and i don`t know why.
Until now, it appears only with one single message, but I am afraid, 
that this could happen more often in the future.
