1935800 - Displayed count of POP3 downloaded messages is sometimes wrong...

Status: RESOLVED FIXED

(Thunderbird :: Mail Window Front End, defect)

Description

[Fred Stluka]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36

Steps to reproduce:

• Hit F5 to download new mail messages from POP3 server
• Observe the informational messages that appear in the footer status bar of the main TBird window

Actual results:

The informational messages that flash by briefly show that several
mail messages are being downloaded.

But the count of mail messages is wrong., typically too high.
For example, there is only one new mail message at the POP3 server,
but the informational messages show that 3 new mail messages are
being downloaded.

I checked the POP3 server immediately before the download.
There was only 1 new message waiting to be downloaded.

I also checked the TBird filters to make sure there were not
additional messages that were being filtered to other folders
and going unnoticed, or being deleted by filters.

It seems that the download is happening perfectly.
Only the count in the informational messages is wrong.

But this wrong count is very disconcerting, leading me at first
to fear that messages were being lost. That does not seem to
be the case. No messages are being lost. The displayed count
is just wrong.

The same problem occurs when I download into one account
from one POP3 server (F5), and also when I download into
multiple accounts from multiple POP3 server (Shift-F5).

Expected results:

The displayed count should have matched the number of
mail messages that were actually downloaded.

Forgot to mention:

On macOS 13.2.1 Ventura, I recently updated quickly from:

• T-bird 91.13.1
  to the following one after the other:
• TBird 102.15.1
• TBird 115.10.1
• TBird 116.0
• TBird 128.5.1esr

This behaved as expected in 91.13.1 and perhaps in 102.15.1.
I first noticed the problem in 115.10.1 or perhaps it worked there also.
It is definitely a problem in 128.5.1esr.

Thanks for your continued support of an incredible product!

Thanks for your report. Messages that have just been deleted are removed from the server the next time a connection is made to get new messages. Unfortunately the number of removed messages is included in the status message.

When messages in a local inbox are deleted by the user, the actual deletion is performed the next time the POP3 server is contacted to get new messages. This removes the confusing status message about message being "received" in this case.

Yeah, that sounds like a very good explanation. Thanks for looking into this so fast!

BTW, effective January, I've decided to bump my annual donation to Thunderbird up from $100/year to $500/year.
It's a REALLY good product, and you guys are providing REALLY good support!

Thanks,
