It is likely that your work system has a system in place that will not let you send outgoing email from outside their network.
Depending on the system they are using, it could be that they look at the ip address range, or they could even look at a particular ip address.
Your mail administrator at work can tell you which system they use, and add you to the approved list.
It may be a little tough if your isp uses dynamic ip addresses, since the work system would use your public ip, not your local 192.168... ip Also your company may have a prohibition against off campus mail transfer.
The way to test this is to see if the email works when using the smtp settings for your local isp. This will tell you if your box has the proper configuration for sending email.
