Many thanks for your reply Emmanuel

But i think that such options should be well known by all. Who has not had a 
problem of SPAM?, or Who has not tried to strengthen security in his mail 
server to avoid sending Spam?. And it is for the danger reasons of SPAM that 
i don't want configure my email server with relays when the mail server is 
out of the LAN.

Moreover, if the PVE developers don't think that such options are good, if 
anybody can tell me how configure my PVE host manually for that can send 
emails with auth and without a relay (and if is possible, with ssl/tls and 
port number to use), please give me a web link for that i can do a practice, 
i will be very thankful !!!.

Anyway, many thanks for your recommendations.

Best regards
Cesar
