    Relaying

    Deep breath <img src=/S/crossfingers.gif border=0 alt=crossfingers width=17 height=16>
    I am running Exchange Server 2000 on Windows 2000 Server behind a Cisco firewall. Our e-mail works absolutely fabulous in the main office. I have people in other sites though (one here, one there, one in another place) who have Outlook or Outlook Express set up to use our mail server. However, they get the 550 relay not allowed error. When I put the IP address of the particular computer in my list of allowed relayers it seems to work. However, cable and DSL clients have their IP addresses change all the time. High administrative overhead thus occurs. Is there a way to effectively (and without getting hijacked by spammers) allow my users to reply to and forward e-mails. Thanks for your time.

    User who have their own ISPs (high band or low band) should use their ISP's SMTP server. If the user is mobile, it's a bit of a hassle to change for in the office and not in the office, but if they don't like that, they should never go home.

    Another alternative is to allow VPN access to enough of your network that they will be working with an allowed address.

    You should have a 'Hosts and clients that successfully authenticate' option in your Routing Restrictions. (it's there for Exchange 5.5). That option will prevent anyone from sending mail through your SMTP server, without having a valid account on your network. (In OE and Outlook's Internet mail options, when you setup an account, there is an option to require a login for your SMTP. Your users will need to set that setting (if they have an email account on your server, they should be able to just tell it to use their POP3 account info).

    Also, for people on the road, that don't have OE setup correctly, you can also setup OWA, which is pretty easy to do, and is quite handy too.
