Postfix SMTP server: errors from unknown[x.x.x.x]

[Jafra]

Pekne nedelni dopoledne ...

mam nasledujici probelm s postfixem, blize upresni Mail, jez je dal uvedeny
od MDS. Dle zahranicnich konferenci jiz nekdo neco podobneho resil, ale k
zaveru jsem z toho nedosel.

Toto je cast grepnuteho maillogu:

Jun  6 10:49:13 mailserver postfix/smtpd[13258]: warning: unknown smtpd
restriction: ""reject_unknown_sender_domain"
Jun  6 10:56:35 mailserver postfix/smtpd[13271]: warning: x.x.x.x: hostname
hostxyz.domena.cz verification failed: Host not found
Jun  6 10:56:35 mailserver postfix/smtpd[13271]: warning: unknown smtpd
restriction: ""reject_unknown_sender_domain"

Diky za pomoc...
