Strange behavior with backup mail notifications

[Catwoolfii]

I've tried to configure postfix, but now I also tuned in for 5 minutes. No need to use something alternative.

Yes, same problem here - I will switch to Postfix on my next installation of PVE. Having said that, it would be nice to fix the double email with ssmtp bug but honesty, life is too short and I've got used to it now

For PVE VERSION 5.4 I'm using ssmtp and it worked for me by editing the file /usr/share/perl5/PVE/Tools.pm
Original line - open (MAIL, "|-", "sendmail", "-B", "8BITMIME", "-f", $mailfrom, @$mailto) ||
Corrected line - open (MAIL, "|-", "sendmail", "-B 8BITMIME", "-f", $mailfrom, @$mailto) ||
