sendmail relay check

[Marek Barton]

Dobry den,

mam problem se sendmailem v tom, ze mi prijima do spoolu maily od
neexistujicich nebo jinak nekorektne se tvaricich domen a snazi se je
dorucit na jine servery, kterym delam relay a tyto servery se spravne
odmitaji se mnou bavit. Ve spoolu mi pak visi tuna mailu, ktery maji
vetsinou chybu: Domain of sender address does not exist nebo does not
resolve. Samozrejme jsou to vzdy spamy. Testoval jsem svuj server a pokud
moje odesilaci domena spravne neresolvuje, tak se se mnou spravne odmita
bavit, proto netusim, jak mi spameri dokazi svoje maily vnutit do spoolu.

Pouzivam sendmail 8.13.8 a muj sendmail.mc je tady:

..
OSTYPE(linux)dnl
DOMAIN(generic)dnl
FEATURE(access_db, btree -T<TMPF> /etc/mail/access)
FEATURE(relay_hosts_only)
FEATURE(virtusertable, btree /etc/mail/virtusertable)dnl
FEATURE(mailertable, btree /etc/mail/mailertable)dnl
FEATURE(notsticky)
FEATURE(`enhdnsbl', `bl.spamcop.net', `"Spam blocked see: http://spamcop.net/bl.shtml?"$&{client_addr}', `t')dnl
MAILER(local)dnl
MAILER(smtp)dnl

pripojuji i hlavicku takoveho mailu:
