ip address

[Vince]

        

why is that in my qmail/maillog when i send email the logs is like this

"delivery 20: success:
216.42.80.32_accepted_message./Remote_host_said:_250_ok_961742865_qp_39020/"


why there is an ip address 216.42.80.32 there may be thats the problem why
my mails are gone in my qmail machine but when i send to to other like
hotmail account i succesfully got the mail.
