Greetings all. I have been using Eudora 7.1.0.9 in windows as my email client for nearly 20 years. Currently it is running with the latest version of windows 10. It was running fine until this past weekend when it suddenly decided not to send emails. I can receive emails no problem. None of my settings in Eudora have changed.

These setting were working fine for years. I called dslextreme technical support for email and they of course said not our problem – They said their mail server is working fine and has been without any issues.

Try setting "Secure Sockets when Sending" to "Required, Alternate Port".
Your provider has probably updated their security requirements, and you will probably have to do the same for receiving soon as well.

Dav...sky - Thank you for responding. My provider's tech support said there had been no changes to the server and it was working fine - no other customers calling in with similar technical issues. Of course that is the easy way out for them. Thank for your suggestion -- I have tried all the options for setting "Secure Sockets when Sending" and none of them permit me to send emails again. There are four options to choose from for "Secure Sockets when Sending" :
Never
if available, STARTTLS
Required, Alternate port
Required, STARTTLS

Any further thoughts or suggestions would be most welcomed and appreciated . Best regards, Joshua

Well they must have changed something, or it wouldn't have suddenly stopped working!
There are two immediate possibilities.
One is that they have stopped supporting TLSv1.0 encryption, which is the only version that Eudora can natively use.
That is fixable using an update to some Eudora program files. It's called Hermes (nothing to do with the courier company!)
https://sourceforge.net/projects/hermesmail/
These new files give TLSv1.2 support to Eudora for sending and receiving.
The other possibility is that they now require an application specific password for mail clients that they deem to be insecure.
Eudora is one of them due to its age since its last update of course!
Have a look at the webmail interface, and check the settings page to see if there's anything that refers to that.
If so, you will have to get the webmail system to generate an application specific password, which you will have to use in Eudora in place of your usual password. Use the option Special>Forget Passwords in Eudora to remove your existing password, and put in the new one when prompted.
Good luck!
Cheers,
Dave.

Dear Dave and fellow forum members, Thank you for the thoughts and suggestions. I have downloaded Hermes and copied the files, per the readme.txt file, to my Eudora directory.

"I still cannot send emails" is about as useful as "Doctor, it hurts
when I do this".

Install, if you haven't already, the esoteric plugin.

Tools/Options/Logging
Enable everything except maybe Search... and Playlists.

Attempt to send some message.

Shut-down Eudora.

Open the Eudora log file, scroll down to the start of that session and
start examining it for the server handshakes. If you cut&paste to a post
here, be careful -- Eudora uses simple UUEncode for masking passwords;
anyone with any skill can decode the sent password.

Installing the Hermes files is always a good thing to do.
If you don't need them now, you almost certainly will at some point in the future when the servers stop supporting TLSv1.0.
You can check that the Hermes update is working by going to the properties of your Eudora persona, selecting the "Incoming Mail" tab, and clicking on "Last SSL Info" after doing a mail check. In the "SSL Info" box it should say "TLSv1.2".
As for the sending problem, did you look at the settings on the webmail interface to see if you can generate an application specific password?
Cheers, Dave.

Dear Dave. Thank you so much for your assistance with this. I copied the hermes files over to the Eudora directory and verified that the modified date was yesterday when I copied the files over. I closed Eudora and relaunched it. I rebooted my computer, a Microsoft Book 2. The last ssl info gives: You have never done any ssl negotiations with any personality since the last time you started Eudora or a negotiation is in progress with that personality. Should the "Secure Sockets when Sending" be set to "Required, Alternate Por" or to "Never" I tried both but neither seems to make an difference. . I still cannot send emails. I am not sure what you are referring to when you say: "The other possibility is they now require an application specific password for mail clients they deem to be insecure.
Have a look at the webmail interface, and check the settings page" -- Where do I find the "webmail interface" (a search for webmail in settings for windows 10 gave no results and I went to Zimbra my email service provider - dslextreme 's, browser based mail client and, perhaps in my ignorance, found nothing under preferences which would seem to effect sending mail from an email client?
"If so, you will have to get the webmail system to generate an application specific password, " How would I go about doing that? "which you will have to use in Eudora in place of your usual password. Use the option Special>Forget Passwords in Eudora to remove your existing password, and put in the new one when prompted." Should I remove the existing password and put in a new one anyway? I so appreciate your assistance and knowledge. I tried to send screenshots here but was unsuccessful - This forum does not seem to permit including pictures/attachments. With my appreciation and gratitude for your assistance. Best regards, Joshua

Hi again Joshua, we really need to know that the Hermes files are working. Checking on the sending side won't be any good as you can't send at the moment anyway, so it will always say that you haven't made an SSL connection!
Do a mail check (it doesn't matter if it doesn't find anything) and then look at the persona properties again, this time looking under the "Incoming Mail" tab. What do you see if you click the "Last SSL Info" button there? Does it say TLSv1.2? If so, the Hermes files are doing what they should do.

Are you sure you're looking in the right place?
Do a mail check, and then go to Tools>Personalities, and select your <Dominant> personality, which I assume is the only one you have.
Right click on it and select "Properties".
Select the "Incoming Mail" tab.
There should be a "Last SSL Info" button at the bottom of that window.
Select it and see what it says. It should say "TLSv1.2" in the "SSL Version" field.
If you can still receive messages (ignore the sending problem for the moment) that should work and should confirm that the Hermes files are doing their job.

Hi again Joshua. That's very good news that the Hermes files are working and you are making a TLSv1.2 connection.
That is one big possible cause of the problem eliminated, and hopefully it will enable things to continue working if TLSv1.0 support is removed on the servers, which it almost certainly will be at some point!
You usually have to have "Required, Alternate Port" selected on most systems nowadays for Eudora to communicate with mail servers, have you tried setting that on sending and receiving? Also make sure that "Authentication Allowed" is checked, "Use relay personality" is unchecked, and "Use submission port" is checked on the sending side.

Dear Dave, Greetings and good day. I have verified the settings and they are now as you requested. There is now a different error message. It seems to be from changing from "Never" to "Required, Alternate Port" -- What should SMTP Relay Personality be set to in the Sending Mail popup. None or <Dominant>? The new error message is:

"SMTP Relay Personality" in Tools>Options>Sending Mail" should be set to "None" if you only have one personality.
Your error message now looks much more like the root cause of the problem.
Basically your ISP has been blacklisted as a possible source of spam!
If you Google "RBL Restriction" you will find out plenty about it, such as here -
https://mailchannels.zendesk.com/hc/en-us/articles/202191674-Fixing-the-550-5-7-1-RBL-Sender-blocked-IP-or-domain-error
Usually I would have thought the problem would only happen sending some messages, not all, because it would depend on whether the receiving server blocked the message or not. You could try sending a test message to me at <dave-***@sky.com> to see if it works.
Whether it does or not, it's something that you need to sort out with your service provider, because they need to get themselves removed from the blacklist!
Cheers, Dave.

Dear Dave, Greetings and good day. I really appreciate your working through this with me. Sending emails just suddenly started working. I did not change anything and it just started sending emails. If it stops again I will call Tech Support at dslextreme.com again and tell them of the error and your link to the zendesk article. Perhaps they cleared the blockage. I will send an email to the address you provided. I hope you get it. Thank you so much for all your support and all your so knowledgeable and helpful assistance.

No there's nothing you can do, they need to find out why your messages are being blocked.
I would be very surprised if other people on their system aren't having the same problem although as I said it depends on who the messages are being sent to, as some servers will honour the block and some won't.
I trust you sent the test message to me using the full address, not the truncated version which is shown here!
It's dave-h<at>sky.com
You said that you managed to send some messages OK. Can you try sending them again (with suitable apologies to the recipients!) to see if they still send now?
If they do, that bears out what I thought, that some messages will be delivered and some won't, depending on the server they're being sent to.
I think your Eudora setttings are now correct.

OK. Well there's nothing else either of us can do about this.
Your outgoing messages are being blocked and only your service provider can address that.
They need to identify which blacklist you are on, and get the block removed.
If you have security software installed, i would do a full scan anyway, just in case you do have an infection on your system which is sending out spam messages! I hope not, but you never know!
I don't think this problem is now anything to do with your Eudora setup.
Good luck. Cheers, Dave.

Dear Dave and fellow forum members, Greetings. Things "magically" started working fine this morning. I am now able to send emails without issue. I wanted to finish the loop on the experience with this issue (at least for the time being) Tech support at dslextreme said they had several recent security and mail server updates. That it can take up to 3 days for the servers to fully update particularly as regards the older lesser used email clients served by these mail servers - but hopefully it is now all working correctly even for a user such as myself using an antiquated email client. They suggested I give consideration to using webmail, something more recent. That I stop using Eudora to avoid this kind of issue in the future. They indicated there is a good chance at some point Eudora will just stop working and not be able to serve as an email client anymore. Best regards and respects, Joshua

Glad to hear that it's working again now Joshua!
DSLExtreme had obviously been changing things, but at least now your copy of Eudora has been patched with the Hermes update it should keep working for a bit longer that it probably would have done otherwise.
Of course all mail providers would rather that you used webmail nowadays as that's easier for them to maintain and support, but many people still want to use mail client programs and store their messages locally, so it will be a long time before they will be able to get away with withdrawing that service.
Although Eudora is struggling a bit now due to it's age, it's still the best mail client ever made in many people's opinion, so I hope there's plenty more years in it yet, especially thanks to the guys at the Hermes project!
Glad to have been able to help.
Cheers, Dave.

Whether it does or not, it's something that you need to sort out with your service provider, because they need to get themselves removed from the blacklist!
Cheers, Dave.

Your further consideration is most appreciated. With best regards and respects, Joshua

Glad to hear that it's working again now Joshua!
DSLExtreme had obviously been changing things, but at least now your copy of Eudora has been patched with the Hermes update it should keep working for a bit longer than it probably would have done otherwise.
Of course all mail providers would rather that you used webmail nowadays as that's easier for them to maintain and support, but many people still want to use mail client programs and store their messages locally, so it will be a long time before they will be able to get away with withdrawing that service.
Although Eudora is struggling a bit now due to it's age, it's still the best mail client ever made in many people's opinion, so I hope there's plenty more years in it yet, especially thanks to the guys at the Hermes project!
Glad to have been able to help.
Cheers, Dave.

Dear Dave and fellow forum members, Greetings. Things "magically"
started working fine this morning. I am now able to send emails
without issue. I wanted to finish the loop on the experience with
this issue (at least for the time being) Tech support at dslextreme
said they had several recent security and mail server updates. That
it can take up to 3 days for the servers to fully update
particularly as regards the older lesser used email clients served
by these mail servers - but hopefully it is now all working
correctly even for a user such as myself using an antiquated email
client. They suggested I give consideration to using webmail,
something more recent. That I stop using Eudora to avoid this kind
of issue in the future. They indicated there is a good chance at
some point Eudora will just stop working and not be able to serve as
an email client anymore. Best regards and respects, Joshua
