Re: Attachment Question

but the attachment was changing to a windat i guess for emailing to myself.

when you send a file attached to an email, usually it can be read on the recipient's mail software. But if you use Outlook or Outlook Express and use the wrong options, your Outlook / OutlookExpress will encapsulate all the attachments into an enveloppe called winmail.dat . It may seem stupid, but it will work if your recipient has Outlook or OutlookExpress. So in a way, you can think of it either as a way of natural selection of your friends, or of a way of bugging your everyday life. Just kidding, the explanation is that it is the only way Microsoft had to enable sending one huge file (say, 10MB) automaticaly split into 5 emails.

to make things short, you just have to clear that option in your email client.

to make things longer, in fact when you send a file attached into an email, it is encoded on Base64 before being added as a multipart inside the mail (next to the HTML multipart if you send HTML emails). that Base64 encoding makes the file globally bigger (+30% average). that's why for instance if your mail server forbids you to send a 5MB email, you can't send a 4MB file because 4MB + 30%x4MB = 5.33MB.
