Send email from multiple SMTP addresses RRS feed

  • Question

  • Exchange 2010 SP1 / Outlook 2010 SP1 / AD2008 r2

    We receive email on three seperate domains. (d1.com, d2.com, d3.com).  Our employees need to send / receive email on all the domains.   Also not everyone has the same primary email domain setup in their AD account.  I can easily receive email on all the domains.  The users can't select one of their non-primary smtp address and send out as that email address.  What are my option for allowing users to send out email from their non-primary smtp address from Outlook 2010.  All the users have a single AD/Exchange account.

    I've attempted to setup additional pop3 accounts on their Outlook client.  The user can then select the pop3 account on a new OL email message.  For some reason I can't get this to work consistently especially if I include attachments.  I believe I have the relay open on the HUB transport because I can get some emails out.(Intermittent success on deliveries).  Emails with attachments appear to fail all the time. 

    The pop3 accounts create a second local data store that is used when I send email from the pop3 accounts.  The OL account settings allow me to switch(Change Folder) on the pop3 accounts.  Can I utilize the Exchange Inbox for pop3 sending?

    Is there another way to accomplish this or a third-party utility?

    Thanks joe

  • You can give them three separate accounts for the three addresses and use different clients to log on to each.

  • 1. What happens when user select From: option in Outlook and send.

    2. You can have seperate mailboxes and provide delegation ,so that mailboxes can be managed from same outlook

  • Hi,

    The step is similar as the link below:


    What you need to do is:(primary smtp address is user@d1.com)

    1. remove user@d2.com and user@d3.com from smtp address list for user account

    2. create the accounts (userD2 userD3) and change their smtp address to user@d2.com and user@d3.com

    3. grant "Send As" permission to user account for these two account.

  • I went ahead and added a mail enable security group like the document explained.  I setup a single user security group for each unique address I needed  to send from.  Everythings fine expect the GAL now has hundreds of additional security groups that don't need to show up for internal users.  The (Exchange Advanced / Hide group from Exchange address lists) will remove the group but it then gives me a "You do not have the permission to send the message on behalf of the specified user"  Is there a workaround for this?
