I am using Fail2Ban v0.8.13. In this version, I had to modify also "config/jail.conf" "action_*" lines used for emailing to include ", sender=%(sender)s", but this version already have that. Though, it no more includes "sendername" in those lines, but the sendmail.conf still use "sendername", so I presume it would work as my current configuration.
