SMTP "valid domain" Problem sending Usage and Performance Reports

Discussion in 'Windows Small Business Server' started by David Lingren, Aug 8, 2007.

  1. I am unable to send usage and performance reports. My SMTP smart host
    rejects them, saying " requires a valid sender domain".

    The report e-mails are coming from "",
    which I'm sure is not "valid" from outside our LAN.

    Alerts are coming through fine, because they are using the "Masquerade
    Domain" I set up in the SMTP Virtual Server. How can I get the usage and
    performance report e-mails to use the Masquerade Domain?

    Changing the SMTP port does not matter. Changing the "Fully-qualified
    domain name" does not matter. Changing the "Outbound Security" doesn't
    matter, i.e., basic authentication succeeds but the e-mail still fails.

    Also, I don't understand the difference between the Small Business SMTP
    Connector and the Default SMTP Server. Where can I go to read up on this

    Thanks for any help you can give me.

  2. Is this Comcast Business or Comcast Residential?

  4. Russ,

    I am using Comcast Residential.

    Marina's suggestion solved my problem - see my reply to her post.

    Are you sure that your Comcast residential account TOS allows you to run a
    mail server? In the Seattle area it is not allowed.

  6. Marina,

    I re-ran the CEICW; there was no entry in the "E-mail Domain Name" field,
    i.e. it was blank. I entered our external domain name.

    I also re-ran the "Set up Monitoring Reports and Alerts" wizard. There is
    no place to enter a "valid sender address"; the only e-mail addresses it asks
    for is the receiving address.

    Finally, I generated a performance report ("send now") and then went to the
    Manage Internet and E-mail page and clicked "Synchronize E-mail".

    It works! Entering the domain name in the CEICW was the answer. Thanks!

    Now, tell me why you have to run the wizard to make this change? Why is
    there no way to enter the external domain name in the Properties page for the
    SMTP Virtual Server or the Smallbusiness SMTP Connector?

  7. Well, the plot thickens...

    Any changes I make in the CEICW wizard's E-mail domain name field show up in
    the "Fully Qualified Domain Name" field on the "Advanced Delivery" dialog box
    in the SMTP Server Properties page. HOWEVER, changes made in the Properties
    page do not get through to the SMTP service. I tried restarting the service,
    but that didn't have any effect. I tried stopping the service, making a
    change and then starting the service - no effect.

    I then re-ran the wizard and made the change there. This time - NO EFFECT!

    I looked in the System event log. When the change works, there is an Event
    ID: 507 from the smtpsvc that says "Virtual Server 1: Default domain is set
    to ...". When the change fails, there is no event 507 in the log.

    Usually, the wizard works, sometimes it fails. The Properties page change
    never works.

    I see that the wizard stops and starts many services, which may explain why
    it is working most of the time. Maybe restarting the server after changing
    the properties page would also work, but this seems drastic.

    Related question - why do alerts use the Masquerade domain name but reports
    do not?

    Bonus question - why do we need the Smallbusiness Connector?

  9. Actually with Comcast "Business" you aren't supposed to run a Mail server
    But I've never had them say anything to a client when they have issues.
    For Obvious reasons, IMO they ignore this.
    Because if a business can't use their own mail server, they might as well
    switch to DSL which WILL allow them to.

  10. I'm not really running a "mail server" from the Comcast perspective. All
    I'm doing is sending e-mail through their SMTP server (the Smart Host), just
    as I do from Microsoft Outlook on my desktop system.

    David Lingren, Aug 10, 2007
  11. Marina,

    Well, it looks like changing the E-mail domain name field in the CEICW
    changes the Fully-qualified domain name field in the Advanced Delivery
    properties page of the Default SMTP Virtual Server. All I did was re-run the
    wizard; I didn't change the property pages directly.

    Did you see my follow-up post with more details?

    No incoming mail on port 25 to an Exchange server?
    Steve, Aug 11, 2007
  13. That's right. Right now I'm just using Exchange to send out server
    performance and status reports, and server alerts (did I hear you think

    If/when we want to use Exchange for "real" e-mail, I plan to use the
    Microsoft Connector for POP3 Mailboxes and get mail through the ISP's "smart

    We'll continue to look like a bunch of individual e-mail clients, e.g.,
    Outlook, from outside our internal network.

    OK no problem. Just didn't want Comcast to shut you down as they did one
    company here for violating the TOS.
