2010 E-Mail Alerts with External SMTP Mail Server

  

I'm using SharePoint Server 2010 internally for testing purposes/development purposes.  I don't have Exchange Server or any other SMTP mail server setup.

I have a hosted SMTP mail server.

Can I connect SharePoint Server 2010 to an externally hosted SMTP mail server for e-mail notification testing?

In this case, my hosted SMTP server requires authentication... so I'm not sure SharePoint Server 2010 will be able to connect.

Any ideas?

 

Thanks!

Configure Incoming Email in SharePoint 2010 with a remote (public) SMTP Server

  
I have a standalone SharePoint 2010 Installation on my local network. Have configured the SMTP Services and a SMTP domain called "internalcompany.com". Created a hosts file entry also for that - now outlook is able to send emails to this domain; it reaches the drop folder and from there SharePoint picks it up and pushes to the document libraries. So far so good. But obviously this is not what I want to do: my www.company.com is my public domain and mail server is mail.company.com - how do I get the local SMTP point to this address - so that if someone sends an email to shareddocs@company.com (just like any other normal id), it comes to my local server and then SharePoint. How do I do this? Remember, my server is standalone and my network is not domain based and does not have exchange.Karthick

Real Server noob having mail problems.

  
Hi Everyone, I have coded my application to send mail and it works fine some of the time depending on the to or from address specified in the particular message but at other times I am getting a relay error. "The server will not relay mail for foreign domains". I HAVE authenticated myself to the mail server using a valid username and password in the code. Basically here is the setup. Our site is hosted overseas in the states with one company, our nameservers are also in the states but with our company not the hosting company. Our mail server is local (that is here in New Zealand). I'm pretty sure that the code is right because I've read dozens of posts on here which point to coding errors and it seems to be right. Do I need MX records or anything like that in some place? What do I do? Thanks
