The maximum email size is set at 25MB for your BT Yahoo! email account. However, you may find it hard to send attachments that are larger than about 20MB as attachments must be encoded so that other email programs can read them. Encoding attachments can add about 33% to their original size. So a 1.5MB attachment would be roughly 2MB after encoding.
If you need to send large files you can try these alternatives:
Zip up your files before you email them
