I don't known where is the probleme.
VM1 can send mail
VM2 can send mail through gmail
but VM2 can't send mail through VM1

I made a litle change in the VM2 smtpd.conf

table secrets file:/etc/smtpd/secrets
listen on lo
accept from any for any relay via secure+auth://label@192.168.0.209:587
auth 

so i have got some interesting logs
