Emails are not downloading from server

Starting today, e-mails on the server are not being downloaded to the client – at startup or after the refresh button. Except, strangely, if I send an e-mail to myself using the client. Then that e-mail and all of the pending e-mails are downloaded upon Refresh. But after that, new ones on the server are not. It is possible that this behavior started with the upgrade to V9. I can’t recall if it was working OK yesterday following the upgrade. I am using POP3 from a desktop Windows 10 computer. Network is working fine. Disabling antivirus doesn’t help. Restarting computer doesn’t help.

I do not have a ‘solution’ for your problem, presently, but I will strongly urge you to do regular automated backups from within eMC.

Correction: I don’t have to send a message to myself to get the refresh working (once), just any outgoing message. Very odd.

From the POP3 log:

(Once again, the account was working fine in V8. The account settings look good. And the authentication works once after sending out an e-mail.)

I have uninstalled and re-installed v9, with no change in behavior.

Was the file you used the same as the one used when you were notified of an available new version?

Would you care to share your POP3 settings?

So host, port and security policy.

The installation file? I downloaded and installed it today, but I think it is the same version.

port 95
security policy: use SSL/TLS on special port (legacy)

I think you mistyped that. The port is probably 995. So the settings are correct.

We would need to see some logs from you to see why the authentication is aborted.
Go to Menu > Settings > Advanced and click on Send Logs.
Add “For Gary” in the subject and click on Send.

I look forward to your analysis of the logs. (I will be out of town and away from this computer as of Wednesday for 2+ weeks.)
BTW, when I say that message retrieval works ‘once’ after a send, I now think that it probably works until I close the app (which I like to do so that I can notice new e-mails on my phone).

I have the same problem after accepting update. I am afraid of losing messages by uninstalling eM.

I did this to myself since no final relent to upgrade reminders goes unpunished, but how long is the typical interval between the latest release, acknowledgement that a bug exists, fix of that bug, and a new release that fixes that bug among others?

I’m having the same problem with POP3/SMTP not connecting to a Roundcube server, all since upgrading to 9. Interestingly, the new release reset my port settings to the standard ones even though special ports (legacy) are needed to access Roundcube mail, but I’ve long since manually corrected that (and tried other things like the Diagnose and Fix buttons) and still have not been able to download mail.

So it’s webmail for awhile until I either wait out a bug fix or try a different e-mail client. I’m reluctant to downgrade back to 8 (or change clients) since I imported almost 20 years of e-mails into eM Client not long ago and don’t want to have do that all over again if I can help it (since I unfortunately can’t just back-reinstall an older version of eM Client, which will make me think twice about future upgrades–a simple “remind me in a month” once a month is much less hassle).

There were three months between releases 8.2.1509.0 & 8.2.1659.0, but only a week between 9.0.1317.0 and 9.0.1361.0, so it is pretty much a crap shoot to wait out a fix?

I did not lose emails when uninstalling (it asks), but somehow all my contacts disappeared. Fortunately I do exports every two weeks and my Carbonite backup had a version that was good.

Gary, did you get my logs? I am back in town and see that there is no new release with a fix for this bug. I can see that I am not the only user experiencing the problem, but apparently it does not affect everyone. Are you one of the developers of eM Client? Should I start looking for a new mail client product?
