I just discovered that many e-mails sent to me by various e-mail lists have been bouncing. Only discovered it when e-mails from yahoogroups did not arrive and I checked the website. The message said, as an example:

Week of Bounced messages

2/26/2006       17
2/19/2006       16

for a total of 550 messages, when they cut off service.

We have broadband and iPhone service from iiNet. We use a G4 PowerMac dual processor tower and a G4 Powerbook, both running 10.4.5. We use Safari and Mail.app. We have a 604T Wireless D-link router from iiNet. Our download limit is 4 Gb, but we have never remotely approached that amount.

Usually the broadband is pretty zippy, but there have been occasions when it has slowed to such a crawl that we had to give up any browsing.

iiNet says probably our hardware or software is at fault, but I doubt it.

Can anyone shed light on what is happening? Is it likely something to do with iiNet's service?

Thanks,
