[horde] Attachment and html display

[miguel]

Hi All,
I'm trying to increase the attachment file size in Horde. I did changed 
the upload_max_filesize to 5mb in my php.ini file but still i can not 
send file bigger than 1 MB. When i try to do so i get a error message as 
follow:


  Request entity too large!


  The POST method does not allow the data transmitted, or the data
  volume exceeds the capacity limit.

    If you think this is a server error, please contact the webmaster
<mailto:castilloalexis at hotmail.com>


    Error 413.

I think is a file size variable value used at 
/usr/local/psa/home/vhosts/webmail/horde/imp/compose.php on line  1029 
and 1030 but i can't find that variable in any script inside /horde/ and 
/horde/lib/ directories so i can set it to a bigger size.

Another concern is inline html. I did modify 
$mime_drivers['imp']['html']['inline'] = true;  so when i receive html 
email everything is display find but the problem is when a try to send 
html email. When the email is received at the other end all html tag are 
displayed as  part of the message.

I would appreciate any help with these concerns.

Thanks.
Miguel
