Something like this can happen if your apache is configured to use php

as both a handler and an output filter.   From the horde/docs/INSTALL file:



    a. PHP interpretation for files matching "*.php"



          AddType application/x-httpd-php .php



    Note: The above instructions may not work if you have specified

          PHP as an output filter with SetOutputFilter directive

          in Apache 2.x versions.  In particular, RedHat 8.0 Apache 2.x

          RPMS have the output filter set, and MUST NOT have the above

          AddType directive added.



Red Hat ships php as a filter via /etc/httpd/conf.d/php.conf so you can

not add the above AddType or you will have problems, including file upload

problems like you mention.

When i create a new mail ,and attach a file , and send it ,

i receive two files , one is the real file ,another 's file size is zero .



if i create a new mail ,and attach two files ,and it will display three files,

if i attache three files ,it will display 7 files .



i don't know what is the reason ,i think it is a bug .





thanks
