Hi,

I am writing a shell script to send mail notifications. But while trying to send a mail from my system, (using sendmail) it says:

"Client does not have permission to submit mail to this server"

I think i need to provide username/password with /usr/lib/sendmail. But I could not find the options in man pages.

Can anyone help me with the syntax please?

Thanx,
Rooky.

if your server uses authsmtp, then yes you will have to. but you have not given enough of the error for anyone to know. it could be just locked down by ip...??

look for lines such as these in the sendmail.mc

if this is the case you have to encode the user name and pass before you are allowed to send email.

see here:-

a true test to see why you cannot send email is to telnet to the mail server on port 25 and identify yourself if it gets that far. from the return codes you will be able to see why you cannot send email.

There is no sendmail.mc file in my /etc/mail directory

my /etc/mail consists of:

sendmail.hf, sendmail.cf, submit.cf

Here is the error snapshot:

oh sorry - thought you administered the remote smtp server.
from the error, it looks you are simply not allowed to relay mail via this server.could be one of many reasons..blacklisted...no proper rDNS...need to authenticate first..
something you would have to check with the server administrator

I do have an account in the server. The question is how do i provide the username/password with sendmail so that the server relays my mail?

i dont know...but i know you can do the way i sent you in that link...

Okay, what do u suggest about the missing sendmail.mc file??
Do i need to create one?

on a redhat distro it should be in /etc/mail.
not sure if it is missing - did you search?? was redhat an rpm install??
if so

rpm -qc sendmail
or
rpm -ql sendmail

or locate sendmail.mc

anyway, you dont need to touch this file for what you want to do as far as i know.
i think you just have to find another way of sending the mail so that it can do an smtp auth when connecting to remote smtp server.
tbh - you shouldnt have to authenticate if you are relaying mail. does this server point to mx records?
