SMTP CONFIGURATION IN MINI2440

I WANT TO SEND MAIL FROM MY DEVICE.
HOW TO CONFIGURE IN MINI2440

Save the capitals for emphasis.

You will need to run an smtp client on the machine.  I use msmtp
stand-alone, although msmtp with Mutt is a commonly used program.

The instructions on the msmtp homepage are quite straight-forward. 
Authentication may be the most difficult part, if needed.

hello,
i currently used smtp its work fine on laptop but its not work on mini2440.
   Smtp* smtp = new Smtp(ui->uname->text(), ui->paswd->text(),
ui->server->text(), ui->port->text().toInt());
in memory allocation time its show Illegal instruction
why this error occured

"Illegal Instruction" error Occurs when you Compile code for one processor
architecture and Try to run that binary on processor with different
architecture.

i.e. wrong "-march=" option

Hello Sandeep Sondagar,
Thanx
I use this 
QMAKE_CFLAGS_RELEASE += -march=armv4 -mtune=arm920t
QMAKE_CFLAGS_DEBUG += -march=armv4t -mtune=arm920t
QMAKE_CFLAGS_MT += -march=armv4t -mtune=arm920t
QMAKE_CFLAGS_MT_DBG += -march=armv4t -mtune=arm920t

my working Qt configuration is 
./configure -embedded arm -xplatform qws/linux-arm-g++ -prefix
/usr/local/Qt -qt-mouse-tslib -little-endian -no-webkit -no-qt3support
-no-cups -no-largefile -optimized-qmake -no-openssl -nomake tools

-no-xrandr -qt-freetype -qt-gfx-linuxfb -qt-kbd-tty -qt-kbd-linuxinput 
-qt-mouse-tslib -qt-mouse-linuxinput

in this configuration i am not use openssl last time.
Send me the solution
