Hello
I need help for this mailx command :

mailx -vvv \
  -r "superlinux" \
  -s "Subject: mailx send mail starttls fullsmtp fullname to some_user@isp.com" \
  -S smtp=smtp.isp.com:587 \
  -S smtp-use-starttls \
  -S smtp-auth=digest-md5  \
  -S smtp-auth-user=4aed0c8909e33260970ca8b0448cc065 \
  -S smtp-auth-password=f92b7d80ddb397a953b8d0748d1478bd \
  -S ssl-verify=ignore \
  some_user@isp.com <<< "some text"

isp mail server accept starttls and accept AUTH CRAM-MD DIGEST-MD

250-STARTTLS
250-AUTH CRAM-MD5 DIGEST-MD5

When using

-S smtp-auth=digest-md5

I got this error :

Unknown SMTP authentication method: "digest-md5"

or

Unknown SMTP authentication method: "DIGEST-MD5"

Any help is welcome.

Hi
From the mailx man page…


smtp-auth
Sets  the  SMTP  authentication method.  If set to
`login', or if unset and smtp-auth-user is set, AUTH LOGIN is used.  If
set to `cram-md5', AUTH CRAM-MD5 is used; if set to `plain', AUTH PLAIN
is used.  Otherwise, no SMTP authentication is performed.

So I would guess it needs to be login,/plain or use imap and would be
cram-md5?

The error come from my local mail server :

Connecting to 192.168.130.80:25 . . . connected.
220 mydomain ESMTP
.........

not from recipient mail server ( smtp.isp.com: ) because I have just forgotten to configure the relayhost parameter on the local mail server.

So the story is not finished.

I finished the configuration, and give news as soon as possible.

After having configured postfix for relaying I am able to send mail using mailx for test.

1°) Add local mail server to /etc/mailrc on sender computer

set smtp=smtp://my_mailsrv.my_domain.net

2°) On the postfix mail server computer verify the /etc/postfix/generic table which contains (left side) the linux user and (right side ) the corresponding ISP user

3°) On the postfix mail server computer verify the /etc/postfix/sasl_passwd table which contains (left side) [smtp.isp_domain] port and (right side ) the corresponding isp user_name@isp_domain:user_password

4°) Use this command on the sender computer (which use smtp parameter which is in /etc/mailrc)

mailx -vvv \
        -r $USER@my_local_domain \
        -s "Subject: mailx send mail my_server_smtp sender_name to user_name@isp_domain" \
        user_name@isp_domain <<< "some text"

Bad parameters in /etc/mailrc prevent mailx to run as needed.
So when doing test check every things.
Obvious isn’t ;).

Any comment is welcome
