Hughes.net was used as smtp (years ago) because it was more reliable. At your suggestion, I've changed back to the mail.dynamicmediasolutions.us smtp setting for my email account and the results are improved but still unpredictable. If I'm patient enough (sometimes as many as five attempts) an email with a large attachment (2-5 mb) will eventually send. BTW, I can tell by the progress bar if it's going to go or not. Hughes.net is a slow boat and if the progress bar zips across to 100% within a few seconds, it's not going to send. If the progress bar gives status (51, 65, 72%, etc.) updates that last at least 10 seconds, the email will send. The other two dynamicmediasolutions.us workstations are happy with hughes.net smtp and any size attachment.

Not sure all that helps, but I don't have the time to keep fooling around with this issue and -- although the process is cumbersome -- I am able to send email from my workstation with large attachments (eventually). So, I think I'm ready to retire this thread unless you have other suggestions.
