Hello!
Sendmail is generating some logs like:

Apr 23 09:13:13 x sendmail[13772]: ruleset=check_relay, arg1=pp.gov.al, arg2=217.24.240.230, relay=pp.gov.al [217.24.240.230], reject=550 5.7.1 Access denied

I have entered this IP(217.24.240.230) in /etc/mail/access like this: 217.24.240.230 REJECT.

I don't know what it is. Is my mailserver sendind spam??

Please help me understand this. Thank you in advance!
