Incoming Mail Relay blocked with users using POP3 Access

[tfoley]

I must have something setup wrong... we keep getting relaying errors.

Here is our setup:

Wingate 5 server with two network cards, one local, one internet.
Wingate is running it's built in Email Server.
12 users running Outlook with POP3/SMTP services

Sending mail from the LAN side is fine.

Sending mail from the Internet side occasionally has problems. We sometimes get the "Incoming mail relay attempt blocked. Mail from MYUSER@MYDOMAIN.CA to someuser@somedomain.com denied".

Since they are logging in through the smtp server and using their name and password, why would Wingate consider this as relaying?

I did notice the error message indicates the user as GUEST, which leads to an authentication problem... however...when I look at the Activity tab, it clearly shows the remote user as authenticated as themselves from some internet IP...

Should the mail server assume the user is authenticated if they logged into the smtp server with a Wingate Username/password and not cause relaying problems?

I assume its just my setup and I've missed something obvious.

Thanks

Aha, I think I found it... however, it appears I am screwed at present:

Wingate shows "Available Authentication Methods", USER/PASS does not have SMTP rights... hence my users that login with their wingate first.lastname and password can't properly authenticate.

However, they all use Outlook and it appears that Outlook/Wingate don't get allow too well.

I'll see if the NTLM auth will work (we don't use Domains here so no one has a NTLM login)...

Ok I've tried the options as listed in the help file, still no go.

No matter what I try I cannot get Outlook to SMTP authenticate with Wingate (Using the WinGate user database and not NT User Database).

Does version 6 address this problem?
