When the Lightning extension is enabled and I attempt to send any e-mail, I get this dialogue:

Confirm

There was a problem including the file file:///C:/DOCUM~1/<NAME>~1/LOCALS~1/Temp/nsemail.html in the message. Would you like to continue sending the message without this file?

OK, Cancel


If I choose OK, the message is sent but the entire body of the e-mail is missing!

If I disable Lightning, e-mails send fine with no dialogue.

I'm using:

Thunderbird 38.1.0 (accessing a Gmail account with IMAP)
Lightning 4.0.1
Windows XP SP 3

Any ideas why this happens and how to fix?

Many Thanks.

That sounds like the normal temporary file created when you send a HTML message. It wouldn't hurt to empty your systems temporary files directory. I have no idea why Lightning has an effect unless its somehow changing the directory used for temp files.

I have done some further investigation, and it appears that the problem was being caused by Avast (not Lightning as originally thought).

There was a recent update to Avast 10.3.223 (and also to Thunderbird 38.1.0).

I have added the file nsemail.html to the Avast exclusion list, to work around the issue and successfully send e-mails with Thunderbird again.

Hope my solution can help someone else with this problem.

Thanks for reporting back. It very well might help someone with a similar problem, if they're savvy enough to search before posting.

BrowseMail ... perhaps it might be a good idea to post this also in the Avast forums.

To BrowseMail: Thank You Very Much!

Joined this forum with the single purpose to thank BrowseMail for his post. I suspected updating Avast was the cause, but didn't know anything about exceptions, etc. Your troubleshooting and sharing with others is Much appreciated. I am sure there are others (besides the ones who thanked you above) who feel the same way...

Interesting post, and after I added exclusions using short and long names, URL, and unqualified names, my message finally worked. And so did the next one. And then the next on failed again. So just kept retrying.... Send, Cancel the error message, OK the next error message, and after some number of tries it worked. So it seems that if Avast! is the culprit (1) adding the file to the exclusion list doesn't help consistently (2) it seems to be more of a timing issue than detection of a virus (3) repeatedly trying is sometimes successful... it can take a dozen or two retries to be successful, whether or not the file is in the Avast exclusion list.

The above all on an XP machine, running Avast! 10.3.2223. I haven't seen the problem on a Win7 machine, as yet, but I see it is running 10.3.2218... so I just got the update. Will report more after I reboot and experiment.

On the much faster CPU much faster hard disk Win 7 machine, I still don't see any problem. But it is quite annoying on the Win XP machine. Seems like an interaction between Thunderbird and Avast….. not sure what change to which program makes this happen now, when it didn't before.

Thanks for your posts. Pleased I could help out. Since adding the exclusion to Avast I have not seen the message any more on my Win XP PC. From personal experience I find that Avast issues tend to be with Win XP, rather than Win 7.

To add the file to avast goto: Settings/ActiveProtection/FileSystemShield/Customize/Exclusions/ press "Add" and put "*\" in front of the filename - like this "*\nsemail.html"

I tried what the previous poster suggested, and it didn't work for me. Specifically:

"To add the file to avast goto: Settings/ActiveProtection/FileSystemShield/Customize/Exclusions/ press "Add" and put "*\" in front of the filename - like this "*\nsemail.html""

Did not work.

Adding the full path to the nsemail.html file in Settings->General->Exclusions did work.

BrowseMail: many thanks, your advice of 17th July has helped avoid domestic distress.

WaltDaniels: I couldn't find the file either, but I just put *\nsemail.html in the exclusion list and that seems to have fixed the problem. I assume it's a file that is created and then dropped on the fly.
