Neither.  Amavis (hopefully you're using the version called
amavisd-new) is a third party content filter you've enabled
separately.  There is an amavis-users mail list where you can get
help specific to amavisd-new.

Apparently amavis isn't working correctly.  If restarting amavis
doesn't help, look in the logs for errors from amavis.

You can (temporarily) disable the content filter and get mail
flowing by commenting out any "content_filter" statements in postfix
main.cf or master.cf, then requeue all deferred mail with "postsuper
-r ALL"

Further discussion of this should move to the amavis-users list.
