I almost always have an internet connection when I want to send a mail,
and having a setup that silently fails to send mail is a horrible setup!
set header_cache = "~/.cache/mutt" # cache headers for speedss
source ~/.mutt/mailboxes # source mailboxes generetated by offlineimap
-# SMTP: msmtp (with queue)
-set sendmail = ~/.msmtp/msmtpq # use msmtp message queue
-set sendmail_wait = -1 # fork sendmail to the background
+# SMTP: msmtp
+set sendmail = /usr/bin/msmtp # use msmtp
set send_charset="utf-8" # only utf8
# GnuPG
