A few more details on this issue from my research: 1) hotmail free storage is not 5 Mb - rather 2 Mb - 2) MSN subscribers is 10 Mb 3) Hotmail has message limits for outgoing mail - a) Free - 1 Mb b) MSN Subscribers - 2 Mb, 3Mb c) 500 messages per day max d) 50 recipients per message 4) There is no limit on incoming message size as far as I can tell 5) Messages that cause the user's mailbox to exceed the limit are supposed to be returned to sender - and are per my testing - IMAIL's rather terse "undeliverable to ..." 6) If the user's mailbox is over quota then the message is returned to sender - also verified - However, I first observed this SMTP_DELIV_FAILED error was on an 8 Mb message to a MSN account. I deleted the message after about 10 tries and told the user he couldn't send messages that large. I've observed several more and it seems generally to have something to do with larger messages. I am fairly certain that Hotmail is dropping the connection. It may have something to do with an elapsed time threshold that's exceeded during transfer because I don't think the entire message is delivered. I think if it were then the error would be returned. I really wish that IMAIL had some better control over the number of retries or the total time for retry so that in these kinds of cases the user would be notified sooner.
