sending e-mail – how it
works (client)
1. mailx creates a fully-formatted
message and passes it to
SENDMAIL as configured in
/etc/mailx.rc
2. SENDMAIL reads a fully
formatted message from stdin
and queues the message in
/var/spool/clientmqueue
3. SENDMAIL attempts to contact
the mail daemon on localhost
port 25.
4. If the mail daemon answers, the
message is transferred using
SMTP and deleted from
clientmqueue, else the message
is left in clientmqueue
