Steps to reproduce:

Start TB, go offline. Compose news message. "Send Later". Go online.

Actual results:

Prompt to send message, when accepted:
Sending of the message failed.
The message could not be posted because connecting to the news server failed. The server may be unavailable or is refusing connections. Please verify that your news server settings are correct and try again.

Error console:
TypeError: this._copyProcess is null sendLater.jsm:236:13
mailnews.send: Sending failed; The message could not be posted because connecting to the news server failed. The server may be unavailable or is refusing connections. Please verify that your news server settings are correct and try again., exitCode=2153066726, originalMsgURI=undefined MessageSend.jsm:335:27

Expected results:

Message should have been sent.

File > Send Unsent Messages mostly doesn't work in this situation at first, the message is sent after several tries.

Seems to work me, sent a message to aioe.test.

We're using eternal-september.org which requires authentication. As we wrote, maybe not 100% reproducible, but certainly happening after a fresh start. Other users on the server complain about the issue, too, in fact, we're just communication their complaints. Besides, the TypeError is very real.

I can confirm that there is something wrong here.

The message in the outbox has the correct ID in the X-Identity-Key: header. But when I go back online (or just do a "Send Unsent Messages"), I get the login dialog for another account that doesn't even carry the group and for which I happen not to have any credentials saved.
Not even the email address matches.

Unfortunately, the NNTP log is not helpful at all.

I can't reproduce it in another profile.

The patch fixes comment 3, not sure about the original reported bug.

Thanks.
I do not see the error message from comment #0.
Could it be the result of using an invalid or inappropriate ID?

If not, sorry for hijacking the bug.

The patch fixes comment 3, not sure about the original reported bug.

When applying the (rebased) patch to a 102 build, it doesn't fix the problem. Some observations:

• The problem can't be reproduced with the C++ module (mailnews.nntp.jsmodule - false).
• Looking at sendLater.jsm, the error occurs here:
  https://searchfox.org/comm-esr102/rev/c98398fe1f2e4652e08c0f369aea13b92a03ff8f/mail/components/activity/modules/sendLater.jsm#236, after resetting process here: https://searchfox.org/comm-esr102/rev/c98398fe1f2e4652e08c0f369aea13b92a03ff8f/mail/components/activity/modules/sendLater.jsm#269

Removing that line 269 slightly changes the behaviour reported in comment #0: The TypeError no longer occurs at line 236, but sending still fails. So there seem to be two issues here: 1) For some reason which wasn't addressed yet, only in the JS module sending fails after going back online. 2) After that, the error handling leads to an additional TypeError.

Reproducing the issue with both send and nntp loglevels at All, we see:

10:15:12.007 mailnews.send: Delivering news message MessageSend.jsm:1084:25

10:15:12.206 mailnews.send: notifyListenerOnStopSending; status=2153066726 MessageSend.jsm:500:25

So the server indeed returns 441 You are not allowed to post to alt.de.test, however, in general, the account is set up to post there, as this successful log shows when posting while already online:

10:20:01.354 mailnews.send: Delivering news message MessageSend.jsm:1084:25
10:20:01.355 mailnews.send: notifyListenerOnStartSending MessageSend.jsm:373:25

NntpClient.jsm:144:18
10:20:01.689 mailnews.nntp: Done with status=0 NntpClient.jsm:829:18

Adding

    this._userIdentity = userIdentity;
    console.log("=== 1", userIdentity, accountKey);
    this._accountKey = this._getAccountKey(accountKey, userIdentity);
    console.log("=== 2", userIdentity, accountKey);

to createAndSendMessage we see correct identity and account key when sending online and also when coming back from offline. So the wrong identity/account doesn't appear to be the issue here (and yes, the bug was hijacked ;-)).

This is a bit puzzling. Looking closely at the debug output, in the bad case there the connection is established first with server reply S: 200, which doesn't happen in the good case since the connection already exists.

If looks like establishing the connection after going back online doesn't work. This suspicion is also confirmed by:
Go offline, prepare message, send later, go online, send unsent - failing
Go offline, prepare message, send later, go online, do not send unsent yet, get messages, sent unsent messages - working.

Maybe the connection after going back online isn't established with the correct credentials. eternal-september.org offers two sets of newsgroups: Its internal ones for unauthenticated users and the "world's" newsgroups for authenticated users. Unauthenticated users can't post to alt.de.test.

Thanks for the analysis, I updated my patch to authenticate if needed before sending POST request. Please try again.

This works now (after solving minor merge conflict with https://hg.mozilla.org/comm-central/rev/abcaf011c387#l2.211).
Please consider removing
https://searchfox.org/comm-esr102/rev/c98398fe1f2e4652e08c0f369aea13b92a03ff8f/mail/components/activity/modules/sendLater.jsm#269
since this will lead to TypeError in case of a real failure.

I tried force-setting mailnews.nntp.jsmodule=true in xpcshell.ini for that test file, it didn't help. Can you take a look?

The problem is https://searchfox.org/comm-esr102/rev/ba62f1e53b7cb7c1df37b51c72ffe18dcbf0adf5/mailnews/base/src/nsMsgAccountManager.cpp#945-946 loads NntpService.jsm, but the test needs to use MockNntpService, thanks.
