Unable to send email, Eudora 7

Hi.  I thought I had this problem solved, but now it's back again; tried searching all over, but no luck; created a trouble ticket, no response.


I'm running Eudora 7 in paid mode on Windows 7 professional.  Our email accounts are provided by Verizon Your Domain; our isp is Optimum.  If you are familiar with Eudora, you know that you can create "personalities," which are essentially different email accounts.  My "dominant" personality works fine -- am able to both send and receive.  However, on my secondary personality, also via Verizon Your Domain, I can receive, but not send email.  Both personalities have identical settings in Eudora (I would attach a screen shot, if I could).  Authentication is allowed, submission port 587 is selected, secure sockets set to never.


When I try to send mail from the secondary personality, the error message is "530 5.7.0 No AUTH command has been given."   I already deleted and re-entered my password.  Does anyone have a fix for this problem?

Hello again


For anybody stumbling on this post, I found the solution.  Many thanks to the genius who figured this out:




Copy and paste the code, and you're good to go!

Dear Howie B, Thank you SO MUCH for posting this! I was really losing my mind. You (& TLBepson) totally saved me!


For readers who need to have it spelled out, here's the solution that Howie B was talking about:


Close Eudora. Go to the Eudora main folder and find the file Eudora.ini . You may not see it immediately b/c Windows 7 displays filenames without extensions; look for it using 'Search' or look for a file with a gear icon, named EUDORA, of type "configuration settings." This is the file you want. Make a backup copy of the Eudora.ini file in case you mess something up.


Scroll down under Settings until you find the line


Immediately under that line, type



Close & save the Eudora.ini file and restart Eudora. Send. VOILA - IT WORKS!


For some of you, this will not be the only fix you need, because you don't have the servers or the ports assigned correctly. BUT DO THIS ANYWAY. THIS IS A REAL BUG AND A REAL FIX. DO THIS NOW SO IT NEVER PLAGUES YOU IN THE FUTURE.


OK, now, to be sure everything works with the port assignments, let's just review the correct Eudora settings for Eudora 7.1:


Getting started – Enter server names - pop.verizon.net for incoming, smtp.verizon.net for outgoing

                              Check ‘Allow authentication’.

Checking mail – Secure Sockets when Receiving: Required, Alternate Port

Incoming mail – Server configuration = POP/ Authentication style: passwords

Sending mail – Check ‘Allow authentication’.

            Secure Sockets when sending: Required, Alternate Port

                        (alternate port default settings are same as above, SMTP 465 & POP 995)

Thank you, thank you, thank you!! This totally worked. I've been using Eudora since 1995, and the thought of having to change e-mail clients was seriously freaking me out.

THANK YOU so much - hopefully, someone will advise Verizon tech support directly about this so they can better advise people when they call.  They had NO IDEA how to help me.

If you are running postfix (Linux mail server) and relaying outgoing mail through Verizon (in my case it's talking to Verizon server through stunnel for SSL):


in your /etc/postfix/main.cf add:


# SG: limit to only plain, login: verizon says it accepts cram-md5, but does not!
smtp_sasl_mechanism_filter = plain, login
