I am having trouble with IE 3.0 mail client on Macintosh PowerPC. When I click on "Send/Receive", I see the request for login go through and get back an ACK OK, but then I receive the following message:
Logging off of mailhost
mail could not be sent at this time.
Mail error. The server did not understand the request.
I have tried this with two separate ISPs and I have the same result. Has anyone seen this before? This only happens when sending mail, not receiving it.
