1286620 - Thunderbird 'Not Responding' for 1-2 minutes after Send

Status: RESOLVED INCOMPLETE

(MailNews Core :: Networking: SMTP, defect)

Description

[rmaf]

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:47.0) Gecko/20100101 Firefox/47.0
Build ID: 20160623154057

Steps to reproduce:

TB sends the email, but freezes for 1-2 minutes, apparently after closing the session with the SMTP server.
I have tested with a clean TB install and the problem stays.

(OS: Windows 8.1 64bit)


Actual results:

My guess is that there is some misunderstanding between TB and the SMTP server at the time of closing the session.

I use smtp-mail.oulook.com server (with Normal Password, and STARTTLS). Following is a quote of the last part of the session LOG. I call attention for the last line "SMTP connection error quitting 804b0002, ignoring":

The LOG with timestamp shows a time delay between 'Service closing transmission channel' and 'connection error quitting 804b0002, ignoring' (see last 3 lines).

Briefly looking for a solution on Google:
https://www.google.com.au/?gws_rd=ssl#q=smtp+error+804b0002
it seems that this is a support question that should have been asked at
https://support.mozilla.org/en-US/products/thunderbird

Apparently the message is sent to the SMTP server which then chooses to ignore it for whatever reason.

I noticed that you are using smtp.hotmail.com. Please try with a different outgoing server.

Matt, I see you ware involved in: https://support.mozilla.org/en-US/questions/1111782

I tried TB with two SMTP servers:
smtp-mail.outlook.com (the connection is initiated with this address, not hotmail)
smtp.aol.com
With both, TB reproduces the same behavior.

I made the same experiment with 'Claws Mail' client. I did not find any problem with this client.
So, I am almost convinced that the problem is not on the side of the SMTP server, but on TB itself or, at least, with the way TB works on my Windows 8.1 64bit system.

rmaf, 
Is what you are seeing "Not Responding" in Thunderbird's windows title bar?

Wayne,
That's right. TB window title shows "Not Responding"

Comment 7

[Wayne Mery (:wsmwk)]

rmaf, during the one+ minute period of not responding, what is the CPU usage of thunderbird.exe per taskmgr?

Comment 8

[Wayne Mery (:wsmwk)]

Sounds like Bug 1332487 - Thunderbird frequently hangs for up to 45 seconds using W10-64 while composing message, and shows "not responding"
