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
