"IMail's relay setting is set to 'Relay for local users'. "
Stop right there. You are an open relay. Don't argue about it, you
are. There are only two settings in Imail that are secure against open
relay: "No Mail Relay" and "Relay for Addresses".
As for the rest, the log snip you provided (if it is complete) says that
you didn't authenticate. If you authenticate, you get a line like:
SMTPD (686901a10000118e) Authenticated [EMAIL PROTECTED], session treated
as local.
It looks like your hello command is HELO. Try changing that to EHLO. I
may be mistaken, but I believe that AUTH is an extended command, and
that you need to hello with EHLO to use those extended commands. List?
Am I right?

Subject: RE: [IMail Forum] Relay Questions
Thanks for all the responses. I'll explain what I'm trying to
do...
IMail's relay setting is set to 'Relay for local users'. What I
am trying to do is allow a web app on our network to email reports on
behalf of our customers through IMail. In some cases neither the sending
or receiving addresses will be local accounts on those reports so I need
to either allow the IP Address of the web server to relay mail, which
doesn't appear to be possible under my relay settings, or have the web
server do SMTP authentication on each email that comes through, which
doesn't appear to be working. I fully understand the argument about open
relays and agree that relaying for local users has it's vulnerabilities
and isn't the ideal method to use, but I'm trying to figure out why SMTP
authentication isn't working.
The error I get back in Outlook is the '550 not local host
yahoo.com, not a gateway' error. It doesn't seem like it's even trying
to authenticate SMTP. In Outlook Express I have my regular account
settings that work, changed the email address to [EMAIL PROTECTED]
and checked 'My server requires authentication' for SMTP. I've tried it
letting Outlook use the POP3 login and also setting it manually. I've
tried logging in as charles, [EMAIL PROTECTED] and
[EMAIL PROTECTED], but it doesn't appear to even be getting that
far. Here's what the logs say...
06:22 08:34 SMTPD(5acf02da0000097d) [66.235.102.123] connect
24.106.211.174 port 1264
