Attachments that are less than 1 megabyte take about 5-10 minutes to send, and anything over 1 MB won't send at all! (no, I don't have dialup ) I'm told (upon Activity Viewer hanging at 100% for several minutes) The server response was: 4.3.2 Please try again later Use the pop-up menu below to try a different outgoing mail server. All messages will use this server until you quit Mail or change your network settings. Message from: [my name and email address] and I can Edit Message, Use Selected Server, or Try Again Later. It's been a while since I've sent attachments so I have no idea when this actually started, but I've never had problems before, regardless of the attachment's size (as long as it fit in the person's inbox and didn't go above my limit) Messages with no attachments are fine. Anyone have any idea? Thanks.
