How to setup user for email, but no login.

[devostyle]

I have a linux box hosting a few domains. I would like to set up the server to allow people to check email without being able to login to the system through telnet, ftp, ssh, etc. Can anyone help?

I believe if you if you set up the users shell to "/dev/null"....it will not let them log on through telnet, ftp, ssh, and etc.

I don't that will restrict ftp, but will restrict telnet or ssh (even better than /dev/null, lots of service accounts have a shell of /bin/false). You need to restrict FTP in another fashion. Check the docs for your ftp server. If you have a lot of mail-only users and few users that are allowed to FTP, you can probably use an allow list instead of a deny list.

I use /usr/bin/passwd. User still has the ability to change his/her password, but nothing else.

I created a script called addmail:

------------------------------------------
#!/bin/sh
# Add a user without login privilages
/usr/bin adduser -n -d /dev/null $1
passwd $1
------------------------------------------

usage = addmail newmailuser

good luck!
