Hi everybody, am new to the forum and need some advice. Use Tiger OS x 10.4.2. Have a Netgear wireless router with my iMac G5. I can send small attachments from my .Mac account (Excel, Word, pdf etc) from my desktop. But any larger attachments (0.5-1MB) and the e-mail stays in my outbox. The error message is: 'This message could not be delivered and will remain in your outbox until it can be delivered. Sending this message content to the server failed.' However, I can upload the same attachement to my .Mac account on the web and send it on from there. So I am guessing it is not a router or ISP problem but a .Mac setup problem. any ideas?
