What is the difference betweeen MAILX and SENDMAIL. I have SENDMAIL configured in my system, how is it different then MAILX, espicially in the syntax of sending mail from the command line.
Thanks in advance

mailx
Quote:
The mailx utility provides a message sending and receiving facility.
It has two major modes, selected by the options used: Send Mode and
Receive Mode.
Send Mode
Send Mode can be used by applications or users to send messages from
the text in standard input.

Receive Mode
Receive Mode is more oriented towards interactive users. Mail can be
read and sent in this interactive mode.

Sendmail
Quote:
sends a message to one or more recipients, routing the message
over whatever networks are necessary. Sendmail does internetwork
forwarding as necessary to deliver the message to the correct place.

Sendmail is not intended as a user interface routine; other programs
provide user-friendly front ends; sendmail is used only to deliver pre-
formatted messages.
More information available in your man pages ($ man mailx)

Question unix mail
I am totally a newbie so pls help me out a here.
Does this mean that even if sendmail is installed, mailx is still used in the background, or is sendmail independently functioning.
Thanks

You need sendmail or some other MTA. You don't need mailx.

If your sendmail is in /usr/lib/sendmail, move it to /usr/lib/no-sendmail. Send an email to another domain (send it to an address that isn't part of your domain). Look at your mail queue ($ man mailq). Your mail will be sitting there unable to send because there is no sendmail (you moved it). Remember to move sendmail back now.
