nekdo vyuziva muj mail server ke spamu?

[bambas]

Zdravicko,
v praci mam nahozeny server na verejne IP na testovaci ucely. Bezi tam 
na testovani postovni server qmail s courier-imap. tughle jsem se 
podival do logu
/var/log/qmail/send a byl jsem zdesen. nicmene tomu trochu nerozumim, 
zde je vypis z logu: (znamena to ze nekdo snazi pouzit muj server pro 
odchozi postu a dokonce se mu to povedlo?)
