Postifx - connect from unknown

Zdravím ve spolek,

řeším na svém malém poštovním serveru takovou věc. V logu se mě hromadí tyto informace:

Sep 27 20:44:27 mail postfix/smtpd[4711]: connect from unknown[192.168.1.1]
Sep 27 20:44:27 mail postfix/smtpd[4711]: disconnect from unknown[192.168.1.1]
Sep 27 20:44:27 mail postfix/smtp^Cd[4711]: connect from unknown[192.168.1.1]
Sep 27 20:44:27 mail postfix/smtpd[4711]: lost connection after UNKNOWN from unknown[192.168.1.1]

Jsou jich řádově desítky za sekundu. 192.168.1.1 je gateway. Pošťák Postfix, systém Debian Wheezy.

Zde je výpis z main.cf

Zkoušel jsem TCPDUMpem odchytit provoz, ale nic než, že to jde z 1.1 jsem se nedozvěděl... Díky za každou radu. Tonda
