Did I just dodge a bullet? Or is this a local issue with one installation? We have many users on Thunderbird and was about to move from 15.7.6821 to 6885. 

I received this "invalid arguments" error with Thunderbird yesterday also. Might be a fluke as it seems to be working fine today.

I'll keep an eye on this thread for a few days here.

Kevind, do you run 15.7.6885 also ? or other version.
Im waiting for respons from SmarterTools before i downgrade, if that is possible.

Same problems here, since running version 15.7.6885

We are weary, wary, and worry that SM fixes will break something that wasn't broken before. Unfortunately this is a pattern that has been going on for some time.  

It would be nice to get some relief from this cycle.

Webbhotell,

Running Version 15.7.6885. Tested it just now and got the following:

Changed to a mailbox running on Version 15.7.6855 and worked fine. Not sure if there have been any recent Thunderbird updates that would have caused this.

So im not alone, probably all is affected, but Smartertools didnt try Thunderbird for this upgrade.

Still waiting for SmarterTools to respond. 3 days now.

Where can we find an older version and downgrade until SmarterTools fixes their bug ?

Hi Webbhotell,

I have opened a ticket with you in order to resolve this issue.

Hi,

  I am seeing the same thing in Outlook Express on Windows XP.  I thought it was something I did with TLS/SSL that is causing it.  I cannot even copy between two IMAP accounts anymore without an error, it seems to copy fine to sent items and other imap accounts, but it gives that error.

Thanks!

Thanks to all who've reported on this. Will wait for the dust to settle before updating my SM v15. 

Same here (SM 16.3.6897).

Since this issue is affecting several users isn't appropriate to share the possible solution rather than opening individual tickets?

I have tried a new build now and didnt see this error, so i think SmarterTools will fix this issue really soon.

Thanks webbhotell sweden,

really hope so.

The same is happening to me also just browsing "sent items" folder trough IMAP in Thunderbird. The folder is not updated and I get the timeout error.

This is what is logged in SM:

[2018.11.28] 13:13:55 [x.x.x.x][18169847] Exception: (PooledTcpItem.cs) Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

ST, is there a timetable for the fix? 

Paul,

  I would think a minor release of v15 + v16 would be coming out this week, as on Monday both products reach EOL, and no more patches!

-dave

@David: I cannot tell you how un-thrilled I am to be reminded of that.

So the (burning) question is: will this particular issue be fixed or will it not?

Hi Paul,

  Sorry to remind you of that.. I was reminded in one of my tickets I opened.. I also am running a CustomBuild and the IMAP issue seems to be solved in that, the CustomBuild was only suppose to add better logging, but it seemed to have fixed my issue too..

   I am waiting for support to get back to me to tell me what is changed in that CustomBuild that could of fixed the issue.

-dave

Good to hear. Long live v15. *sigh*

As we close out the month, just checking on the status of this. I was hoping there might be a patch this week.

The strange thing is, nothing in the 15.7.6885 release notes regarding IMAP updates, so wonder what changed...

We have several customers impacted by this problem. Any ETA on the next public release of SM 15?

Hey Scott, do you know what version of Thunderbird these user's are on?  I updated to Thunderbird's latest release 60.3.2 and I'm able to send emails against SmarterMail15 without seeing that error.

Hi Larry, Thanks for checking this out. I was able to reproduce withe TB 60.3.2 and SM 15.7.6885.

I sent several messages and some messages were sent with no errors. When there is a problem a dialog box is displayed with the following message:

"Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors.
You can retry or save the message locally to Local Folders/Sent-test@mydomain.com."

Apparently this issue can be sporadic. Some folks on here seem to have gotten a custom build that fixes the problem. So AFAIK we are still waiting for the next minor update to v15. I am still on 15.7.6821 here.

Hey Scott, thanks for extra info.  I'll try it again with sending multiple emails and see if I can reproduce it.  Thanks.

Ok all I checked in with the developers who work in this area and there is a fix, however, it's not yet in the latest release.  I know there are about 3 people who do have a customer build and they each confirmed that it was resolved in their environments.  Paul had already stated this previously and I didn't catch that...so sorry for any confusion.

We will complete a SmarterMail15 release tomorrow to get this fix out to the community so keep an eye out for an update.  Thanks!

Great. I'll look for the update.

Thanks, Larry! 

v15 is still very stable & reliable here. 

We have no plan to upgrade to v16, will run v15 a couple of more years, nothing new to warrant an upgrade.

1. Smartertools should start LTS version so we dont must upgrade.

2. Every domain claiming one account from licencepool is ridiculous. Get rid of that "feature" will make me want to upgrade.

Hi,

I'm experiencing this same exact issue.  

Thunderbird version 78.6.0

SmarterMail Build 7642

It happens often, and seems random, as well.  Any suggestions on things to try or check?

-Freddy

Hello Fred,
Please open a ticket with support and we will get working on getting this fixed as quickly as we can. Likely, after you open the ticket, we will need a log with the error inside of it as well to help us figure out what exactly is returning that error. Thank you in advance. 

Josh, 

I don't have a license for support and maintenance.  I'm using the Free version of SmarterMail offered through my hosting company.

Is there a way to pay for a one time support for the Thunderbird issue without purchasing 1-year maintenance and support?

Fred, Thanks for your update. I've sent you a direct message to get some more details from you.
