The config option 'mta' is a misnomer, since it does not set an actual
MTA to use, but a commandline tool that provides email sending service.
Both SendMail (the mta, not the spelling) and postfix provide a
'sendmail' binary, and have compatible commandline interfaces. the
'mail' command is a different binary, provided by a typical non-mta
package (on ubuntu: mailutils).
If you want to use postfix, remove all of SendMail, install postfix, and
check that you have a 'sendmail' binary (e.g.: sudo which sendmail).
Then configure fail2ban to use 'sendmail'.
