Thanks,

The timeout sometimes happens when you are trying to send a document with a large attachment.

I have no idea why Yahoo would say no data because to my mind an attachment is data, unless it has no text in the body of the email and that is what it’s complaining about.

The attachment of in excess of 2MB would in some cases exceed an ISP or mail services limits. As you found zipping didn’t help, this could be due to the size as mentioned above.

But you perservered and get the file that triggered the alert, good job.
