What's SMTP server for Eudora to send out mail on SBC DSL connection?

Posted on 2006-05-18

Dear Expert,

I have a DSL connection through SBC one place and a Cable modem connection through Comcast another place.

I am required to use EUDORA on my laptop which I connect wirelessly to a Belkin router at the former and a D-Link router at the latter location.

At the latter location, I have no problems sending outgoing messages from Eudora since I use or's SMTP (as my email address is a Godaddy email account).

However, at the former location with the SBC DSL, I can't find an SMTP that will let me send out email from Eudora.  Not,,,,, nor any other SMTP from .  It just gives me the error: The SMTP server said: 530 authentication required - for help go to which doesn't help because it does not apply to my circumstances.

1) Can you recommend a few SMTP servers that will allow me to send out email from Eudora through my SBC DSL connection, both wired or wirelessly?

I even tried to setup my laptop as an SMTP server, installing a program called "Free SMTP Server" from  This also didn't work, the SMTP server saying: 550 Invalid recipient: <any email address that I tried>.

2) Why didn't Free SMTP Server work?

3) Lastly, are there any "free" remote SMTP servers out there anymore?  Like in the past, SMTP servers that allow anybody to send any mail without the server requiring authentication nor filtering according to email address or what not?

Thanks a lot for your speedy help!!!

    Greetings, rawray !

    1.  You should ask SBC Techical Support what is the SMTP server name.  Yahoo usually requires authentication, so that has to be selected.

    2. Not sure of your setup for Free SMTP Server, so I do not know why it did not work.

    3. Nerdshack email service has a free SMTP server which does not require authentication.

    Best wishes!

    Hi war1 et al.,

    1. I did ask SBC Tech Support, and after they were unable to help, they said to contact Eudora.  I'm aware of the authentication issue, I don't think that's the problem.  But let's say we forget about the SMTP search, and I'm going to just use Godaddy's SMTP for my Godaddy email account.  Why doesn't work within my DSL network (using Eudora)?

    2. I didn't do any fancy settings for "Free SMTP Server."  I just installed it the most standard/braindead way and started up the program and expected it to run.  Does that help?

    3. Thanks for the nerdshack link.  However, they require email addresses like to be used in the "From:" field when I want to be able to use my address.  This raises an issue from point #1, I think SBC Yahoo! is expecting an SBC or Yahoo! email address in the "From:" field.  So the question becomes, are there any "free" remote SMTP servers out there anymore that allow you to use your own email address/incoming server?

    Thanks war1.  To everybody including war1, any additional help is greatly appreciated.  I may end up splitting points.

    Just wondering if SBC block SMTP servers other than itself ... to fight spam.

    rawray, War1 already pointed this out, but the simple solution is to set up authorization in your Eudora. You don't just click the "allow authorization" box, you have to get an SSL certificate and add it. SBC help should have that procedure.

    Almost everybody is disallowing third party relay these days, so using a free smtp isn't a wise approach.

    does not allow unauthenticated relaying
    Configure your mail client to use "" as both your incoming and outgoing e-mail server .
    Don't forget to enable authentication for both incoming, and outgoing messages.
    Our servers don't allow unauthenticated relaying.
    If you have difficulty configuring your mail client, please consult the questions page.
    If you are still having difficulty, please contact the Postmaster. ..."
