[mu4e bug] "replied" flag is not set after sending a reply

[vladmaraev]

Describe the bug

I don't quite understand the mechanics of setting "replied" flag and In-Reply-To field, but I don't see In-Reply-To field while composing a message (I think I could see it in previous versions of mu4e). After sending, the incoming message doesn't get flagged with "replied" flag.

When examining raw contents of incoming messages I see that: For incoming message Message-ID: AS8P251MB02623BAA6AD3F7419E1A9ED1CB8F2@AS8P251MB0262.EURP251.PROD.OUTLOOK.COM For my reply: In-Reply-To: AS8P251MB02623BAA6AD3F7419E1A9ED1CB8F2@AS8P251MB0262.EURP251.PROD.OUTLOOK.COM (REDACTED's message of "Thu, 22 Aug 2024 15:08:39 +0000")

In the thread view these messages look as they should.

How to Reproduce

It happens each time I reply (mu4e-compose-wide-reply).

Environment

• GNU Emacs 29.4 (build 1, aarch64-apple-darwin23.5.0, NS appkit-2487.60 Version 14.5 (Build 23F79))
• mu4e - mu for emacs version 1.12.6

Checklist

• I am running 1.12.x release
• I can reproduce it in "emacs -Q"

The In-Reply-To field is hidden by default; unhide it through the "Field" menu or by changing mu4e-draft-hidden-headers.

[vladmaraev]

Thanks for you reply. I didn't realise this. But now when I see it it is empty.

[vladmaraev]

Sorry I was mistaken. Now I can see it. But still, I don't get the 'replied' flag after the reply gets sent. I will try my best to further debug it myself.

[vladmaraev]

Just to mention that the issue is still present, even though In-Reply-To matches parent Message-ID.

[djcb]

Setting the flags of the "parent" message when replying/forwarding is handled in mu4e--set-parent-flags. Are you able to see if it is called after you reply?

And can you find the "parent" message, with something like:

mu find msgid:AS8P251MB02623BAA6AD3F7419E1A9ED1CB8F2@AS8P251MB0262.EURP251.PROD.OUTLOOK.COM

[vladmaraev]

Yes, I can find it. I tried with a more recent reply, and can find the message referred to from "In-Reply-To" field.

Perhaps a simple tests (this requires 1.12.8 for the logging).

1. send yourself a test message
2. wait until you receive it
3. turn on mu4e-logging
4. reply to your test message, send it, now in the log you should see something like:

2025-01-29 12:14:43.055 -> (add :path "/home/example/Maildir/sent/cur/1738145676.d73b29b5474b695a.abcd:2,S")
2025-01-29 12:14:43.155 mark [email protected] as Replied
2025-01-29 12:14:43.155 -> (move :docid nil :msgid "[email protected]" :flags "+R-N" :maildir nil :rename nil :no-view nil)
2025-01-29 12:14:43.155 -> (remove :path "/home/example/Maildir/drafts/cur/1738145676.0e5301a366d00669.abcd:2,DS")

and now the message you sent in (1) should get the "R" flag.

Do you see something similar?

This has gotten stale... closing for now. Feel free to reopen with the requested information -- thanks!

Sorry, I rolled back to 1.10.9 so I was inactive. But now I decided to try 1.12.9 again and managed to test it. Here is the log, it seems to be looking quite different.

@djcb Would it be possible to reopen the issue?

[djcb]

Hmm, the logs seems to show saving a draft message, did you follow the steps?

Yes, this is what I get (I tried once again). I forgot to mention that I am using msmpt as sendmail-program, not sure if it matters.

Seems your messages never make it to the sent-folder, i.e. mu4e-sent-folder, or?

Can you check if your draft messages include an "Fcc:" header? Note that you might need to check the raw file on the file-system.
