przekierowanie:

printf "$user@$hostname\n" >> /root/.forward
service sendmail restart
# b)
wysylamy maila telnetem:

telnet adres_ip 25
mail from: root@smol
rcpt to: smol@smol
data
tresc maila
.
quit

su smol
mail

ŻEBY PRZEKIEROWAĆ TRZEBA WEJŚĆ W KATALOG cd / i stworzyc plik .forward: nano .forward i wpisać do niego adres mial
na ktory ma byc przekierowany mail
