I don't buy it. Julie's suspicion of her Registry change, which in my testing has no effect whatsoever on the SMTP transaction, does not compute. > So I've abandoned my hypothesis in favor another, but unknown to me, > explanation. I think your suspicion of oversize messages is very well-founded. As you can read in my last post, I observed both Yahoo and MSN disconnecting after oversize messages without sending a 552. I could send an undersize message both before and after the disconnected sessions from the same account and IP, so I have real doubts as to whether any other characteristics are taken into account other than size (note the attachments had a variety of non-executable extensions). -Sandy To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
