--MailErrorSummaryTo=rcpt not working

[AlexanderSch90]

Hey,
znapsend should send me an email in case of errors. What do I need to create a mail ?! I already have = root; = admin; = myexternalMailAdress@gmx.de tried. Unfortunately there is an error everywhere when calling the program with this Option:

--MailErrorSummaryTo = rcpt

Syslog says "Unknown option":
Feb 10 16:20:48 pve2 systemd[1]: Started ZnapZend - ZFS Backup System.
Feb 10 16:20:48 pve2 znapzend[32143]: Unknown option: mailErrorSummaryTo

Maybe it is because i use this version? https://github.com/Gregy/znapzend-debian
Should i make an Issue there?
