resend async email.

[zw963]

Hi, I use mu4e, and use emacs-async package to sent email.

But, in some case, when I sent, I found the internet is not connect.

In this case, my sent email is moved to Maildir: /sent, But, the email
is not sent out actually.

How to do for this case?

Thanks.

See log, I could see:

Sending via mail...
Delivering message to opensuse@opensuse.org...

If internet is available when sent, correct output is:

[mu4e] Message sent
Delivering message to opensuse@opensuse.org...done

Current, my internet is not so stable, is there exist a workaround for this?

thanks

If your connection is unstable, you should use by default mu4e in queued
mode, when you are sure you are well connected flush all your queued
mails.

I agree this is a problem but it is hard to fix this only on the async
side, probably we should find a solution both on mu4e and async-smtp.
(i.e telling mu4e the mail have been sent from the async callback)

I create a issue for mu project too, thanks

My network is not so bad in most case though.

But this case will happen occasionally.

the problem is if this case happen, I hard to do the resend operation.
I have to copy this email content and create a new mail send it again.
I think this operation maybe make mu4e index broken.

It is a very bad experience for me, currently, I prefer to waiting email is sent
and not use async email package. it better ...

This is definitely a bug. The a sinking on package is supposed to signal an error if the email fails to send, which would leave the buffer in an unsent status.

At the moment, this is just an experimental package to show proof of concept. I would recommend not using it in light of this problem.

This is too late, when the error is sent (if it was) mu4e or whatever mua have moved
the email to sent recipient, it is why I said we have to find a fix in
both packages (probably around the message-sent-hook usage).

I use it since months, and when used on a valid connection it is safe to
use (this email have been sent async).

You can modify the value of smtpmail-queue-mail automatically when your network is connected or disconnected.
This ensure your mails are queued when network is disconnected.
You can achieve this by installing https://github.com/tromey/emacs-network-manager library and using something like this:

(use-package NetworkManager
    :config
    (NetworkManager-add-listener
     (lambda (state)
       (setq smtpmail-queue-mail (not state))
       (when (eq major-mode 'mu4e-main-mode)
         (let ((pos (point)))
           (mu4e~main-view-real nil nil)
           (goto-char pos))))))
