[Postfixbuch-users] was greift hier?

[Werner Detter]

hallo, 

vielleicht steh ich grad aufm schlauch, kann mir kurz jemand sagen warum ich die folgende 
meldung auf meinem mailgateway im logfile erhalte ? 

Dec  5 13:48:59 mailgw postfix/smtpd[22173]: connect from unknown[67.15.62.10]
Dec  5 13:48:59 mailgw postfix/smtpd[22173]: lost connection after CONNECT from unknown[67.15.62.10]
Dec  5 13:48:59 mailgw postfix/smtpd[22173]: disconnect from unknown[67.15.62.10]
Dec  5 13:57:16 mailgw postfix/smtpd[22313]: warning: smtpd_peer_init: 67.15.62.10: hostname srv1.ultimatefreedownline.net verification failed: Temporary failure in name resolution

ich denke ich habe keine smtpd_*_restriction die auf forward/reverse dns eintrag prüft: 

smtpd_recipient_restrictions =
        check_helo_access pcre:/etc/postfix/helo_checks,
        check_sender_access hash:/etc/postfix/access,
        check_client_access hash:/etc/postfix/access,
        check_recipient_access hash:/etc/postfix/access,
        reject_non_fqdn_sender,
        reject_unknown_recipient_domain,
        permit_mynetworks,
        reject_unauth_destination,
        reject_non_fqdn_hostname,
        reject_invalid_hostname,
        reject_rbl_client cbl.abuseat.org, 
        reject_rbl_client sbl-xbl.spamhaus.org,
        
smtpd_sender_restrictions = 
        check_sender_access hash:/etc/postfix/access,
        check_client_access hash:/etc/postfix/access,
        check_recipient_access hash:/etc/postfix/access,
        permit_mynetworks,
        reject_non_fqdn_sender,
        reject_unknown_sender_domain,
        reject_rbl_client cbl.abuseat.org,
        reject_rbl_client sbl-xbl.spamhaus.org,
  
warum erhalte ich hier einen "Temporary failure in name resolution"?
