I am using amavisd-smtp-20010808 with postfix 20010228
and KAVP and have a problem with attachments. They seem
to be messed up sometimes, especially when received by
mail clients on Windows computers. Some strange empty
lines appear between header tags and that is what could
cause problems. Additionally some reports have been
received that the keycoding is messed up from time to
time, but the genral problem is in screwed attachments
I have seen there was some kind of a bug in older
version of amavis related to metamail. Metamail is
installed on our system as well, but I could not find
from any scripts or configurations if it is used somewhere.
I am using based BestLinux R3 which is more or less
close to Redhat 7.0.
