Thunderbird doesn't synchronize IMAP until the program is closed

[Jeremy LaCroix]

Binary package hint: thunderbird

I'm using 64-bit Jaunty Kubuntu on two machines. I use an IMAP account because it's important to me that I have the same email on both machines.

While I was using Intrepid, changes to my email happened immediately. For example, if I had both machines running with thunderbird open on both, if I deleted an email on one, it would be deleted on the other. Now, in order for the changes on one Thunderbird to propogate to the other I have to close Thunderbird. As soon as I do, all the changes I've made propogate to the other thunderbird and then on my webmail.

The first thing I did was call my email support number, and they reset my account and that didn't fix it. They said no configuration changed, so it must be Thunderbird.

Another example is if I have Thunderbird open and webmail open in Firefox, then I delete an email in Thunderbird, the email isn't deleted in webmail. Once I close Thunderbird, the changes I've made to my messages then appear in webmail. For whatever reason, Thunderbird does something when it closes to synchronize, instead of in real time.

Steps to reproduce:
1. Open Thunderbird for an IMAP account
2. Send a test email to that account from a different account (such as webmail)
3. No change in Thunderbird
4. Close Thunderbird
5. Open Thunderbird again
6. The new email appears

Expected behaviour:
The new email should appear as soon as step #3 above

Actual behaviour:
The new email only appears at step #6 above, after closing and re-opening Thunderbird

I found the problem, the following needs to be set to true in the config editor:
mail.imap.expunge_after_delete

Confirmed on Jaunty with thunderbird package version 2.0.0.21+nobinonly-0ubuntu1.9.04.1

Noted that reporter no longer uses Launchpad
and there has been no activity for 11+ years.

Using Thunderbird 68.8 and Ubuntu 18.04 I was
not able to reproduce a problem following the
steps in the bug description. I used my mail
provider's webmail and Gmail to send, receive
and delete mail. No problems found, I did not
have to close and re-open Thunderbird to see
newly arrived ir deleted mail.

Marking "Incomplete" in case anyone subscribed
to the report still sees an issue.
