How big is the file that you're trying to email, and what's the error
message that you get? If the error message contains details of your email
address or the recipient's email address you may want to remove them before
posting here! Also, when you say a small clip, what's your definition of
small? I've known some ISPs and corporate mail servers to block attachments
larger than 2MB!!
Sometimes a recipient's ISP places a limit on attachment size, so if it's
their ISP's mail server (or their corporate server) that's reporting the
error then you should consider using a feature in Outlook Express (assuming
that's what you're using) which will allow you to split your large message
into smaller chunks. Assuming that the recipient is also using Outlook
Express they can reassemble the file at their end.
