Thank you for your quick responce. I appricate that.
I tried what you sugested and used 7z to compress the 7.5 MB file. That worked well and dropped the file size to 5MB. When I tried to mail it again, it still would not go through.
Have you heard anything about Yahoo limiting file size as a way of reducing spam, something called greylining?
I turned off my virus scanning temporarly to see if that would help, but even that did not.
Thank you again.
