I am having trouble with my out box sending emails I have composed. No big files or attachments clogging the works. Just not sending. Any help please?

Your SMTP server is down, or your attempt to login to it is not working properly.

Are you on a new ISP or traveling? Is this a newly-configured email client or email account?

[zipperzap]

Not a new email client. But I am traveling. I am traveling with 3 other guys that have macs that are working just fine.

If they're using the same email account/server as you, then you may try creating a new email account in the email client, use the same outgoing & incoming settings, but name it differently, then try to send the emails.
