General :: Create Users For Email Only And Not On The System?
Feb 20, 2011
i am reading on sendmail and so far my impression is, we must create users on the system (where sendmail is installed) for them to be able to access their emails. I wanted to ask that is it possible to create users for email only and not on the system ? Like lets say i want to create a user client named noony, who gets and sends his email to my sendmail server, but i dont want to actually create the user on my system ?

I need to add linux and samba users using a shell script, it falls over because you are prompted to set a password.
I had a similar problem when installing the samba package using a script because it asks for confirmation after the command, I got round it using --force-yes -y as below.
apt-get install samba smbfs swat --force-yes -y
I suspect and hope you can do something along those lines when creating a linux user and a samba user, something like
smbpasswd �a username ?

i have to create 100 users in Linux with some password can it be done in one go i tried newuser command but the home directory is not created for those users.
plus when i login for the first time into a server i got
EXECUTING /etc/profile ...
EXECUTING .profile ...
EXECUTING /xyz/abc/bin/setenv.ksh file ...
before the prompt. The above three lines shows that some kind of script was set to run when a user login for the first time that will create the home directory (if i am not guessing wrong)and never run if user login again.

I just loaded a new server. I did an adduser with the -c and -p to create a few new users. The users show up in /etc/passwd, but when i try to SSH to the server as them I get access denied.
Is there somewhere I have to add their names to allow them to SSH in? they have /bin/bash as their shell accord to passwd.

I'm trying to send mail to other users on the same host, but they don't arrive.I've tried using mail and alpine. Both programs apparently work fine, in that they behave as expected and apparently send the email.But when logging in as the recipient, there is no mail in /var/spool/mail, and nothing in alpine INBOX

I want to make a webserver with multiple users allowed to login through SFTP to a specific folder, www.Multiple users are added, lets say user1 and user2, and all of them belonging to the www-data group. The www directory has an owner www-data and a group www-data.
I have used chmod -R 775 on the www folder, but after I try to create a folder test through my SFTP server (using Filezilla) the group of the directory created has only r and x permissions, and I am not able to log in with the second user user2 and create a directory within www/test due to a lack of w permission to the group.
I also tried using chmod 2775 on www directory, but without luck. Can somebody explain to me, how can I make it so that a newly created directory inherits the root directory group permissions?

In my Windows environment, I use email client such as Microsoft Outlook to connect to our email server to send email with the following configuration:
Incoming server (POP3): 995 - (requires with SSL)
Outgoing server (SMTP): 465 - (use encrypted connection SSL)
[code]....
And the mail server requires user ID login and password.how do I setup a text command based email client in my Linux (Centos 5.1) to send out email through the existing email server above, which is in another machine? The email client has to be text command based because I need to use command line to send notification email from anothar application installed in my Linux (Centos 5.1) Since the email client will only be used to send email notification, I don't require setting up of an email server in my linux.

Using CentOS. I have a cron setup to run this command: Code: /var/test.sh | mail -s "Test Cron" mr182@somewhere.com The email is sent but the output of the script is not in the email body, it's just blank. I know there is some output because there are some echo statements in the script.I don't want to get an email for all cronjobs, just this one.

I have an email setup where all of the emails from our email host is downloaded to our Linux server using Fetchmail. Then some of the incoming emails are sent to an MS exchange server (server1.domain.com) using Postfix. What i want to do is to send a copy of all emails to Another server (server2.domain.com) for redundancy.Can postfix be configured to send copies out to both?

Id like to ask you some advice. Im currently using as mail server Lotus Domino. Because of many reasons I need to create an SMTP server that receive the email from Dominothat relay those email into an authenticated SMTP on the internet. How can I do that? I create a Debian virtual machine and I installed Postfix. I edit the config file and set the relay host (authenticated SMTP on internet),the mtp_sasl_auth_enabled and smtp_sasl_password_maps parameters. If I try to send an email using that SMTP server I got a message that say âœRelay access denied, check the email address†What did I do wrong

I'm niomi and I'm the first account with sudo. I add an account, bob. niomi can get in reliably on active mode. (maybe relevant?: passive doesn't work) bob is jailed to his home directory, niomi is in ftp-special which gives her access to /. bob can't log in and his shell is set to bin/false. What could have gone wrong?
