# Alternatively, you may hardcode the mailer using code like one of
# the following:
-# Use "/usr/sbin/sendmail -t" to send emails. The envelopesender
+# Use "/usr/sbin/sendmail -oi -t" to send emails. The envelopesender
# argument is optional:
#mailer = git_multimail.SendMailer(
-# command=['/usr/sbin/sendmail', '-t'],
+# command=['/usr/sbin/sendmail', '-oi', '-t'],
# envelopesender='git-repo@example.com',
# )
