Hi,

I want to use mailx command. Can I hv an example of the syntax?

Receipient - abc@yohoo.com
subject - test
content - this is just for testing

Hi,
echo "this is just for testing" | mailx -s"test" abc@yohoo.com

for files:
mailx -s "subject" recipient < file.txt

Shalom Ngoh,

I use it via cron as follows

2>&1 | mailx -s "cronjob ran" someonewhoexists@nds.com

If I see that email address on my gate mail servers log, I'll have to punish someone. :=) (joke).

Hi,

Thanks for ur reply.

1) What is the diff between mailx and sendmail?

2) As I know, we can configure mail relay host at /etc/mail/sendmail.cf. Is this setting only applicable for sendmail? How about mailx?

regards.

Hi,
mailx is the "frontend" for sendmail. So mailx uses sendmail.

Hello,

1) What is the diff between mailx and sendmail?

Sendmail is standard UNIX implementation of SMTP protocol. Where as mailx is frontend. More advanced front end is Pine.

2) As I know, we can configure mail relay host at /etc/mail/sendmail.cf. Is this setting only applicable for sendmail? How about mailx?

Nope. Read the above answer.

Actually, mailx just wraps email for sendmail.

In reality, if your sendmail.cf isn't configured correctly, then mailx won't work (to anything outside the box).

IE - if you havn't configured a smart relay in sendmail (DS), and your server doesn't "know" how to get to your email server, then, a mailx -s "test" you@yourdomain.com

Hi,

Per my understanding after went thru all the replies, the mailx will invoke the sedmail to send mail. Am I right?

Currently I'm facing a problem as described below.

Our mail relay server is Trend Micro IMSS.

In /etc/mail/sendmail.cf, I set the 'Smart' relay host to this IMSS.

By using root and sendmail command, the mail can be reached at IMSS but the IMSS treats it as a SPAM.

By using root and mailx command, the mail can be reached at IMSS and divert to the destination sucessfully.

Q1) Why above problem happens?
Q2) What is the diff between /etc/mail/sendmail.cf and /etc/mail/sendmail.cw?
