sendmail-program with msmtpq

[Xavier Maillard]

Hello,

I am trying to use msmtpQ with the regular mail-mode.
I set sendmail-program to "msmtpq" and `send-mail-function' to `sendmail-send-it'.

My goal with this setup is to queue my outgoing messages when I am not
connected.  There is something wrong at some point; when unplugged,
msmtpq is doing the right thing: it queues the outgoing message but `sendmail-send-it' would consider it as unsent.

Here is the log:

[2018-11-10 08:12:02.017] Sending...
Added to /home/xavier/.cache/mail/sent
sendmail-send-it: Sending...failed to   mail for [ -oi -f xavier@maillard.im -oep -odi -t ] : couldn't be sent - host not connected; enqueued mail as : [ 2018-11-10-08.12.02 ] ( -oi -f xavier@maillard.im -oep -odi -t ) : successful; 

Due to that behaviour, calling C-x m again is just asking if I want to erase the *mail* buffer instead of creating a new one.

What's wrong ?

Regards

I suspect that your program exits with non-zero exit status in this
case, but I cannot be sure because you don't seem to show the entire
message.

sendmail-send-it expects a successful sending to exit with zero
status.

Here is a test from the command line:

# With connection ON
$ cat /tmp/test-mail | ~/bin/msmtpq xavier@maillard.im
  mail for [ xavier@maillard.im ] : send was successful

$ echo $?
0

# With connection OFF
$ cat /tmp/test-mail | ~/bin/msmtpq xavier@maillard.im
  mail for [ xavier@maillard.im ] : couldn't be sent - host not connected
    enqueued mail as : [ 2018-11-12-06.05.45 ] ( xavier@maillard.im ) : successful

$ echo $?
0

As far as I can see, it should be ok. Does sendmail-send-it expect a message or something like that ?

Thank you.

Hello again,

in fact, no matter my online status, calling `compose-mail' after a
previous call to `sendmail-send-it' behaves the same.

I did not pay attention before but, I have many `sendmail-errors-XXXX'
buffers with msmtpqs's output (exactly the same output than when
calling it from the terminal).

Is it safe to "silent" msmtpq via an advice in the `sendmail-send-it'
function ?

Please show the full message you get in the *Messages* buffer after a
failure to send a message.

Sorry, I don't understand what that means, nor how it is related to
the issue at hand.  What do you mean by "silent"? if you mean
"silence", I still don't see where did you silence it and why do you
think it might be unsafe to do that.

In fact, there is no failure just an output from the msmtpq command
which I suspect, is not what is expected.

I read through msmtpq source code (thank you FOSS) and I find a way to
make the command be quiet.

I tested it and it no longer bails out any error anywhere (and my
mesages are either sent or queued depending my connectivity).

Thank you for your help.

As an interested bystander: did you suppress the error, or did you
change the return value so it didn't return a message (only the 0)? My
understanding is that msmtpq should return 0 whether it sent the message
or queued it, right? Can't `call-process-region' ignore the message, and
only pay attention to the return value?
