[imp] I cannot send files over 500 kb approx

[Argimiro Veiga]

Please, I need aid.  I am desperate.  Already I have looked at myself all
the *. ini and I do not find the problem and the messages in the list do
neither give me the solution.

When I try to send a message with an attach file of but of 500 kb, aprox.,
the message is sent with an attach empty. On the other hand, with files
less than 500 k. functions ok.

The error.log of the Apache:

[error] PHP Warning:  fopen(/var/tmp/impatt93Ycpi) [<a

Por favor, necesito ayuda. Estoy desesperado. Ya me he mirado todos los
*.ini y no encuentro el problema y los mensajes en la lista tampoco me dan
la solución.

Cuando intento enviar un mensaje con un archivo adjunto de mas de 500 kb,
aprox., el mensaje se envia con un adjunto vacio. En cambio, con archivos
menores de 500 k. funciona ok.

Muchas gracias
