Hey people,

I've just completed a SBS2003 to SBS2011 migration and most email accounts are working fine. However some POP3 accounts are receiving this email for SMTP.

Task 'jobs@dishtec.com.au - Sending' reported error (0x800CCC67) : '  The server responded: 421 4.3.2 Service not available'

Open in new window


I'm relatively new to managing Exchange, so it be great if you could explain and include steps in your suggestions :)

Thanks.

Have you started the POP3 service?
Are the POP3 port/s open on your new server?
Is the user POP-enabled?

With SBS 2011 everything is configured for using POP3 only is the "Microsoft Exchange POP3" service is set to manual and not started by default so if you want your users to connect by using the POP (the same for IMAP) you need to start the service it would be good to change the startup type to automatic so after a restart the service will be started automatic.

Ofcourse when you have users connecting from outside your network you need to configure your router to let the POP port (110) through to the SBS server

Yes to 1 and 2. How do I check if the user is POP enabled?

Thanks.

The problems with reply email signatures

Do you wish that you could place an email signature under a reply? Well, unfortunately, you can't. That great Exchange/Office 365 signature you've created will just appear at the bottom of an email chain. What a pain! Is there really no way to solve this? Well, there might be...

You can check this by going to the users mailbox properties within exchange management console (Recipient Configuration, Mailbox) and on the mailbox features tab you can check if this is enabled (this is the default option)

But reading your question again, you are talking about sending via exchange, when you connect via POP and want to send via exchange you are trying to relay, this is not configured by default.

Just make sure you have configured outgoing authentication in Outlook and follow the server configuration, by this document: http://blogs.technet.com/b/sbs/archive/2008/09/19/how-to-configure-sbs-2008-to-host-pop3-imap4.aspx and don't forget to continue to this link at the end of the article:

Thanks for the info, I setup the services to automaticallyu start previously (during the setup) and firewall ports were also open.

I have configured a new receive connector as described in the second link, I'll see how it goes tomorrow.

Cheers

Thanks, your links worked. I had to configure a receive connector and change the client emails to use SMTP port 587 and TLS.
