Re: SMTP using SSL with authentication - problem



There are some special security settings for Domain Users using Outlook
Express. If you logon Windows using Domain User A and create an Outlook
Express POP3 account with Domain User B's email address, username and
password, you can receive POP3 emails but you CAN NOT sent email with this
email account. The error in this situation is the same as what you got
('454 5.7.3
Client does not have permission to Send As this sender.) Of course, if you
logon Windows using Domain User B and use User B's own username and password
in Outlook Express, everything will be OK.

Something will make you hate Outlook Express. If you logon a local user
account on your Windows, you can use any Domain User's email, username and
password without a problem. You are restricted only as a Domain User. Too
bad, you can't use "Run As" to start Outlook Express.

PL,

Maaan... this is weird...! I created a third test account and it works
just
fine as well... ! So now I have 2 good test accounts and 1 bad test
account
+ 1 bad legit user who's complaining...
Everything seems configured right on the FE server... could there be
anything on the BE server? Shouldn't be like POP3 right? POP3 has to be
the
same on both FE and BE, in fact you set it on the BE and the FE inherits
the
POP3 settings it seems like. But the SMTP seems to be independent between
FE
and BE servers?

Not sure what to try next!? Here is the error message: (modified personal
info)

The message could not be sent because the server rejected the sender's
e-mail address. The sender's e-mail address was 'Per.Test@xxxxxxxxxx'.
Subject 'Test from home using POP3/SMTP', Account: 'DOMAIN - PerTest',
Server: 'mail.domain.com', Protocol: SMTP, Server Response: '454 5.7.3
Client does not have permission to Send As this sender.', Port: 25,
Secure(SSL): Yes, Server Error: 454, Error Number: 0x800CCC78

HELP!

Thanks!!

Check:

Client submission SMTP VS in ESM:
1. Basic with TLS/SSL enabled
2. Anonymous is disabled
3. Port 25 for TLS, Port 587 for SSL (they are not the same for
SMTP....)
4. Sender Filter, Recipient Filter, Connection Filter, Sender ID Filter
are
unchecked
5. "Allow all computers which successfully authenticate to relay,
regardless
of the list above" Unchecked
6. Both Users has same permission in the "Permissions for submit and
Relay"
dialog box

Outlook Express:
1. Correct username and password are entered (for some reason, you may
or
may not need to use email/UPN as the user name)
2. "My server requires authentication" is checked under "Outgoing Mail

Help!

Setup POP3/SMTP connectivity on this FE 2003 server, plus only allowing
authentication and SSL for these users.

Tried to setup a test user using Outlook Express, and the test user was
able
to sucessfully recieve and send emails.
Setup a second user, with same privileges, and this user is able to
recieve
(POP3) emails, but not able to send emails?!
Get a 454 error, but this user should be able to send if authenticated,
just
as well as the first test user... !?

What could cause this kind of problem?

TIA!!
