Problem sending mail from email client to exchange server SMTP
Hi,
I've just installed a new SBS 2011 server, exchange all working, no problems.... however.... We have a couple of users who connect using POP accounts, again, all working, mail downloading without a problem.... until - they try to send mail!
Normal outlook/exchange account access is receiving and sending no problem.
What should I be configuring/looking for in order to get it working?
If I try to send an email, all I get is:
The message could not be sent because connecting to SMTP server mydomain.local failed. The server may be unavailable or is refusing SMTP connections. Please verify that your SMTP server settings are correct and try again, or contact the server administrator.

Hi,
How could I verify if the SMTP service is operating correctly? Our normal outlook/exchange connected machines are sending mail just fine!
Our MX Records are working correctly, with inbound and outbound mail to the fully connected exchange/outlook clients...
It's just the sending from outlook express which is failing.... via a normal SMTP using port 587

Go into your device manager and verify that SMTP is running and not "stopped" and that it's set to start "automatically".
You said that this is a new server; is there another Exchange server on your network currently?

Where would I find SMTP, under services? I've had a look and can't find any service related to SMTP?
It is a new server, which has replaced an older SBS 2008.....
Thanks

You need to configure the clients to use TLS, and then to connect on the port set in the Client Receive Connector. SBS will not allow you to relay email through the connectors already assigned to port 25.
Why aren't the users on Outlook Anywhere? POP3 is an awful protocol, no place in a business email system.
The advice about SMTP above is WRONG - SBS 2011 doesn't use the SMTP service. If you are receiving email correctly from the internet then the SMTP part of the Exchange Transport Service is working correctly.

Thanks Simon,
These are MAC machines running thunderbird..... They receive fine, but sending.... I just don't know where to check the right ports and settings I should be using?
Can you point me in the right directions, lay out what I need to do
Thanks very much

No idea on the Mac. I don't have anything to do with them.
Does that version of the Mac OS have an Exchange client so you can use web services?

Hi,
No it's just using a standard smtp server settings. Take the mac out of the question and imagine it's a windows pc with outlook express..... What smtp settings should I use with a pop account?
