Well, I've just successfully sent a Word file and .jpg attachment to myself, so I guess it's nothing to do with the ISP. This is strange....I've proved I can send e-mails out with the attachments, but no-one else receives them ?!
I do have Alarm Zone Pro and McAfee Anti-Virus installed, so I'll check to make sure the settings aren't causing a problem. But if something's blocking outgoing attachments, howcome I can send them to myself ??
Answers on a postcard please !
