    Ad-aware tells me that EudPriv folder contains a "data miner". If I remove this folder Eudora appears to function normally but the deleted folder, and data miner are reformed. What is happening here? Is "spyware" involved? How do I remove it? I'm using 5.1 paid mode.

    Any idea why Eudora is still checking for incoming mails even though there is no network connection? The options for no email checking if there is no network connection have been checked.

550 Authentication Error

I'm trying to use Eudora to send and receive email from an account other
than my ISP. In Outlook I can do this by setting my outgoing mail server to
my ISP server and then selecting the "My outgoing server requires
authentication" option. This prompts me for the user name and password for
for my ISP account.

With Eudora, under Getting Started, I can select Allow Authentication but I
am never asked for a user name and password. I recieve the "550 relaying
mail to <domain name> is not allowed" error.

In article <E8BXa.493$ XXXX@XXXXX.COM >,  XXXX@XXXXX.COM  says...

  Which ISP are you logged on to?
  What is your mail server configured to?

  You must logon to the ISP you wish to send through.

  Logon to the ISP where your SMTP / return address is configured to.

  You are *probably* connected to one ISP with your mail server or
  return address configured to another, this is a common anti-spam
  preventative by ISP's to keep unathorized users from using their
  mail servers to distribute SPAM.

  550 Relay Denied Error


  You most likely have an ISP which is now requiring SMTP Authentication.
  You will need to Upgrade to Eudora 4.3+
  Eudora 4.2.2 with the following lines added to the Eudora.ini file
  in the [Settings] section.

I'm clearly missing the crux of the issue. I am connected to my Verizon DSL
service. No problems getting to my Verizon account. I can access my other
email account from Outlook, Outlook Express and Netscape Mail but not with
Eudora. The problem is that I need to authenticate so that I can relay mail.
All of them are configure to use outgoing.verizon.net as the SMTP server.
However, I don't see anyplace in Eudora where I can enter any
authentication. As I said, in Outlook, when I select the authentication
check box, it then asks what my Verizon user name and password are. At no
time does Eudora ask so what is it authenticating with?

So when I select Allow Authentication from the Getting Started tab, what is
supposed to happen? I'm using Eudora 5.2.1 Light and am not about to pay for
it if I can't use other email accounts.

Eudora will use the authentiation information that you have provided for
the incoming mail server. For what you want, you should look into the
version 6 betas ( http://www.**--****.com/ ) for the "relay personality"
feature. This will do what you want.

Alternately, you could create a personality just for sending mail.

Maybe this needs to be more remedial for me. Here's the new config. I have
downloaded Eudora My ISP is Verizon. I'm trying to get mail from
another domain, let's call it foo.com. I only have one account configured in
Eudora. It's looking at pop.foo.com for incoming mail which works fine. This
requires a user name and password which are configured. I have
outgoing.verizon.net as my SMTP server. However, I don't see any place that
I can put a DIFFERENT user name and password to authenticate this with
either during the configuration or when sending the email. Under the
"Sending Mail" tab I have selected Allow authentication and under SMTP
replay personality I have tried both "none" and "<{*filter*}>" both of which
seem to behave the same. I can't find any documentation on this feature. Can
I configure a personality? Is there some simple toggle switch I'm not seeing
that makes this work?

The exact error I get is:
<{*filter*}>, 1 messages left to send., RCPT TO: XXXX@XXXXX.COM  [10:16:29
Can't send to ". The server gives the reason: '550 relaying mail to
hotmail.com is not allowed'.

I would be willing to blame it on Verizon but both Netscape Mail and Outlook
work fine. They just suck as email clients.

I pre-6 Eudora, the way to do this was to generate a sending personality 
(Foo.com via Verizon) with all info necessary to send as a VZ account.  
Only the reply-to address should be foo.com.
Then a filter would change the personality of an incoming mail from foo.com 
to foo.com via verizon.  That's as complicated as it gets.  See:
< http://www.**--****.com/ ;

Thanks to all for the help. Jennifer's email seems to be the answer.
However, since I have the light version it doesn't appear that I can create
personalities to test the soluiton.

2.#5.1.0 smtp;550 5.1.0 Authentication required

I'm a novice MCSE. On the side I'm supporting a small network (SBS - 3 
workstations - Exchange).  The small network was built nicely by a networking 
company who became too expensive for my client, who is a friend, who asked me 
to support it.

The first Thing (and only thing) I've done was changed the Administrator 
Password on the server.

Now I've had reports of this error when users try to reply to emails.

 The e-mail address could not be found. Perhaps the recipient moved to a 
different e-mail organization, or there was a mistake in the address. Check 
the address and try again.
  <mydomain.com #5.1.0 smtp;550 5.1.0 Authentication required

They can email successfully if they type out the email address, but it will 
not work when they simply hit reply and send.

Does anyone know what I can try to do to fix this?

3.550 Authentication turned on in your email client


Please help as I am new to this and have been dropped in the deep end with 
this problem...

All users cannot receive SMTP mail and any messages sent to any email 
address get a NDR which has the message "550 Authentication turned on in your 
email client" as the reason.

We are able to send and receive internally, and send externally.

Our set up is that the MX records point to an online filtering service 
(emailsystems.com) and they then forward mail direct to our server. Mail is 
getting to them and being sent, but coming back as failed with the NDR as 

I have run through our exchange setting with them and they match their own 
email servers (and I have not changed them). We had a problem with our domain 
host which is now resolved, but in the process of getting that sorted out, 
something else has gone wrong. The DNS records are showing as correct with 
static IP's where appropriate.

The server is set up only to receive mail from a specified range of IP 
addresses (for email systems) and does not need authentication for delivery 
of mail to it.

Have i missed another built in security to SBS2003? 

I have re-run the email wizard and rebooted without success.

Any help greatly appreciated.
