    My question is:
    "Do I need to have separate IP addresses for each of my domain names so I can allow SMTP access through the domain names (i.e,"

    Here some issues I'm having:
    I have setup multiple domain names on my box successfully.
    I have created users and emails addresses with no problem
    Users can access their email through a email client like thunderbird.
    The problem is they can receive email but they can't send email.
    There are 3 domains. Domain number 1's email addresses can send and receive email but the other 2 domains can receive but can't send. The error from the email client is:
    "Sending of Message Failed.
    The message could not be sent because connecting to the SMTP server failed. The server maybe unavaiable or is refusing SMTP connections. Please verify that your SMTP server setting is correct and try again, or else contact your network administrator."

    The log files show the following when I try to send email:
    Apr 2 07:57:29 esss000418 postfix/smtpd[2053]: connect from[]
    Apr 2 07:57:29 serverName postfix/smtpd[2053]: setting up TLS connection from[]
    Apr 2 07:57:30 serverName postfix/smtpd[2053]: Anonymous TLS connection established from[]: TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)
    Apr 2 07:57:30 serverName postfix/smtpd[2053]: disconnect from[]

    Any advise with this would be greatly appreciated.
    Thank You

    No, you dont need separate IP addresses. Just point all "smtp" subdomains with dns A-Records to the IP address of your server.

    ping result of SMTP

    Thanks for your reply Till,
    I created an A Record entry for smtp at the GoDaddy level and in the ispConfig level. I just have to wait a bit till this takes hold. I'll let you know the results shortly.

    As a side note. currently, if I ping shows my machine's ip address.

    When I dig it shows:
    ;; ANSWER SECTION: 1529 IN CNAME 1529 IN A

    SMTP requires authentication

    I figured out the issue was I didn't put my username in mail client for smtp authentication.

    My Bad.:p
