Hi,
this is a simple command line utility to send
emails.
It uses your default email account from your
email applications (modest).
To send an email just enter the email subject,
receiver address(es) and type in your message
(finish up with ctrl+d). Examples:

mailcmd -s subject recipients
your message

or

echo "your message" | mailcmd recipients

If you have configured modest for autoupdate, the message
is sent the next time you are online. Otherwise it stays in your
outgoing folder until you push "send/receive" (in modest).
