If you are using Exchange then authenticating to the SMTP server can only
help resolve your problem even if your admin says it isn't required. From
your email Exchange is doing exactly what it's supposed to, not relay
unauthenticated mail to any domains not marked as "incoming" or explicitly
In Mail.app edit your SMTP server and select authentication. For the
username use domain\username and Mail.app will authenticate before sending
any mail. You migt also be able to use your userPrincipalName
(email@hidden) but since you are doing a legacy migration I'd
suggest sticking to the NetBIOS method of domain\username for now.
Actually I should have simply stated, use the same credentials you entered
for the incoming server since you can receive mail. :)
I did want to mention something about the "Exchange" vs. IMAP accounts in
Mail.app. Apple decided to use OWA and IMAP with the Exchange account to
filter out Exchange specific mails which for me meant it wouldn't show some
meeting requests. This was the case with 10.3 so I'm not sure if it is still
hosed up with 10.4 but I'd be careful using the Exchange mode vs. a standard
IMAP account. I was hoping they finally went the WebDAV route like Entourage
with the Exchange accounts for 10.4 but no such luck.
