Sendmail Accounts

Hi Linux Experts,

I have a good experience about Intallisng Linux Servers, DNS, Sendmail, Webmail Ftp... well, but I have a question about the Sendmail Accounts. I usually create the accounts using the Account Manager of Linux, but some one said me that it´s the wrong way, because there are another form (the correct form) to make it. Could you explain me what is the way to create account, onlu for sendmail??

Thanks

On a Linux system with the usual IMAP/POP server (the UWash IMAP server) it is reccommeded that one  create an email only account with a login shell of /bin/nologin for security reasons. This prevents an email only account from being able to actually log in to the server. It really doesn't matter what tool (Account Manager, useradd or direct edit of passwd/shadow/group) is used to do this.

There are alternatives to the UWash IMAP server (Cyrus, Courier, etc) that allow email accounts without needing a Linux account.

You'd only need "accounts in sendmail" if you've configured sendmail to do SMTP AUTH to allow roaming users relay privs (and sonfigured sendmail to use sasldb).
