SharePoint 2010 - Configuring incoming emails without local SMTP

  • You can look at configuring E-mail settings using the advanced scenario as described on MSDN here.

    Be nice Mike!

  • Hi,

    installing the SMTP service on the frontend machine(s) is not a requirement. But you have to know the address of and have access to the SMTP server.


    Outgoing email settings:

    In CA, add it explicitly under "System Settings" -> "Configure outgoing email settings" -> Outbound SMTP server (use the FQDN)


    Incoming email settings:

    In CA, add it explicitly under "System Settings" -> "Configure incoming email settings". If you want to use Directory Management Services (aka DMS, gives you advanved emailing features and user directory integration, such as AD), then you choose

    "Use the SharePoint Directory Management Service to create distribution groups and contacts?" YES

    The form will expand, and you can specify the FQDN of the smtp server.

    If you don't want to use DMS, then leaving settings as they are in "Configure incoming email settings" is good enough. Optionally, you can restrict the servers, from which SharePoint will accept emails, by adding them to the "Safe Email Server", but leaving it to "Accept mail from all e-mail servers" should be just as fine.


    A long story short: Just configure the outgoing email server, and leave the incoming settings as they are. Do modifications, if you want to use Directory Management Services.

    I hope this was helpful.

    Best regards,

  • Hi Martin,

    Have you even tested it?
    In my opinion, the SharePoint server uses a windows service to capture mails from a e-mail drop folder. As far as I know, the Exchange doesn't dorp mails to folder. So, I don't think it is possible to use Exchange server as the incoming mail server directly.

  • Agree with Jinchun.

    You don't have to run SMTP on Front-End Web Server but you have to run it somewhere to get the email in the "drop" folder as eml file and configure your SharePoint (the timer service) to be aware the location of the drop folder and pick up the eml files from there.

    The easiest way is to run SMTP server on Front-End Web Server and select "automatic" as shown here

    The not so easy way is to run SMTP server somewhere else and share the "drop" folder as network shared folder and give permissions to your SharePoint Timer Service account. And in the settings as shown, select "Advanced" and then give the network shared folder as \\myserver1\drop\

    Martin W Angler:
    We would like to have the minimal setup, with Exchange and without local SMTP.

    I used "Use the SharePoint Directory Management Service to create distribution groups and contacts > No". But when I configured it like this it simply did not work. So eventually I installed local SMTP and asked the Exchange admin to configure connector in Exchange to pass the mail sent to to the SharePoint server.

    So what do we miss to configure it without local SMTP? What kind of rights for SharePoint are needed in Exchange and what kind of settings have to be adjusted in Exchange? Can SharePoint directly look into and pick up mail from Exchange, how does it knows that mail for are for SharePoint? As far as I understand from Exchange admin, SharePoint was not picking the mails from Exhchange and mail was picked up only after local SMTP was configured...  

    We need SharePoint only to receive mail and that is all, no additional mailboxes or anything like that…

    Thanks in advance!
