Can't sent email from Outlook 2003 using IMAP

I'm trying to setup Outlook 2003 on a workstation using IMAP. I can receive email but cannot send email outside of our company . When I click  Send/Receive I get the following error message:

Task 'Checking for new mail in subscribed folders on' reported error (0x800CCC0F) : 'Outlook is unable to download folder (null) from the IMAP e-mail server for account Error: The server did not respond to this IMAP command before the connection was terminated. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'

I also get the following error message: A timeout occured while communicating with ( company name being our company name) . The connection has been closed.

If I send an email to someone in our company it works fine but if I try to send outside the company it fails.

What kind of server are you using, Exchange or Linux based?  To deduce if this is a client configuration (Outlook) issue or a server issue it would be useful to know if you are you able to send email over a Webmail connection without a problem?

The server is FirstClass version 9  running on a MAC server, OS 10.4.9.  I have several Blackberry's  setup up using webmail / IMAP4  that work without any issues. I can send mail without a problem from the BlackBerry's but not from Outlook using the same settings.
To confirm that the issue is with an Outlook setting setup Thunderbird and try sending an outside email from there.

I can't get Thunderbird to send or receive.
OK, so there's an issue with the sending piece of the server.  

It makes since that your blackberry's don't have an issue since they use the BB servers to send the email, and only receive email from the server.  As a temporary solution you could setup a gmail account and emails routed though that SMTP gmail connection.  However this is far from a good long term solution.  I need a little more information.

First, if you log into webmail does sending email to an outside address have any problems.

Second, has outlook (or any other email client besides blackberrys) ever worked?  Have you tried this on multiple computers?

Third, is this server internal or external to the clients (if it's internal try using the internal IP address instead of

Fourth, do you have any support from FirstClass?

Before you close the ticket do you mind letting me know why you didn't respond to my last post.  No hard feelings if you don't want to continue working on this, but it's not accurate to say "no answer" when I have a post waiting for your response that could lead to a solution.

Maybe the asker is unresponsive because I gave them the solution or suggestion that lead to the resolution.  I would propose the points be awarded to me.

cmathis65 original question is basically;

I'm trying to setup Outlook 2003 on a workstation using IMAP.

I think comment ID: 22755224 gave him the solution that he needed to resolve this issue.

If he tried my suggestions;
1) Test with webmail. If this works then that confirms the issue is with the local machine and he can double check the settings.
2) I ask if this works on other machines.  The point that he uses the word "a" in his question means this is probably an issue with a single computer, and not with others.  If he compares the settings between computers this may resolve his issue.
3) Try using a static IP address. By using an IP address instead of a domain name it eliminates the possibility of a DNS issue.
4) Call FirstClass. If he has support with FirstClass then he might be able to find the solution faster with a call to them.
