[msmtp-users] msmtpq not verbose?

["Pablo S.M." <joseleopoldo1792@...20...>]

Hi,

Is there any possibility to make msmtpq (i'm not speaking about msmtp!) more quiet? I mean, not to throw a lot of information like: 

mail for [ -f XXX@...20... joseleopoldo1792@...20... ] : send was successful
  mail queue is empty (nothing to send)

I'm trying to use it with emacs with
(setq message-send-mail-function 'message-send-mail-with-sendmail)
(setq sendmail-program "/usr/bin/msmtpq")

and emacs always gives an error, although the mail is being sent... I think the reason is (maybe) this infomration emacs gets back from msmtpq.
