Greetings Bob , 

Well  look , as i have already demonstrated to u i put a line in my /etc/hosts assosiating My.Virtual.Domain.Net with 127.0.0.1 , the generic localhost address but sendmail did go along with it . As an OpenBSD user i met on irc said to me sendmail seems doesn't pay any attention to what /etc/hosts states. As both you and Rick Stevens said earlier sendmail is doing an nslookup on machine sending the email ( at least that far i understood ) . So i guessed if i run a named on my machine who would be able to resolve My.Virtual.Domain.net to an ip address i could that way satisfy sendmail and send the email . Of  course i can be wrong on that . The intresting thing though is that without running a named i managed to use pine to send an email by putting kostassf cha forthnet gr as the Sender address and not user My Virtual Domain net . Doing that i observed that although i have settep up correctly the Real Username in Pine when i received the email the From String stated kostassf !
cha.forthnet.gr as the Sender and not Kostas Sfakiotakis as expected . It seems that the receiving smtp server accepted the transfer by assuming the sender email address as Sender because it was the only thing that it could verify . 
Anyway as i found out running a named could produce a lot of problems to me and to the Internet in generall . So i think i will stay with what i fouund out untill now , which seems to be quite safe and use my forthnet email account as Sender whenever i use pine and not any local account . My thanks to both you and  Rick Stevens that assisted me up to this point . 

Regards , 
 Kostas
