Debian Etch i Postfix

alaraf - 25-04-2008 00:54
Jakiś czas temu postawiłem serwer pocztowy na Trustix-ie, ale dystrybucja niestety umarła (a wielka szkoda). Szukałem jakiejś alternatywy i padło na Debiana.

Zainstalowałem Etcha i zabrałem się za konfigurację Postfixa. ÂŻeby ułatwić sobie pracę poszukałem jakiegoś HowTo i znalazłem stronę Debian Admin.
Niestety, coś nie wyszło z SASL2 i postanowiłem wszystko odinstalować przez aptitude. Potem ręcznie wywaliłem katalogi, które uznałem za zbędne po deinstalacji pakietów (/etc/postfix i /etc/dovecot).

Spróbowałem ponownie zainstalować postfixa, ale nie udało się. Zinstalowałem więc ponownie exim4 z nadzieją, że wrócę do standardowego SMTP Debiana i wtedy instlacja Postfixa zastąpi exim4.

Nistety, podczas instalacji wywala mi:

Postanowiłem przeinstalować system bo stwierdziłem, że zajmnie mi to mniej czasu, niż szukanie konfliktu w pakietach. Po reinstalacji systemu udało mi się zainstalować i skonfigurować Postfixa.

Jeżeli zaś chodzi o main.cf, to sugeruję jeszcze parę ustawień, które powinny trochę poprawić bezpieczenstwo:
disable_vrfy_command = yes
smtpd_sasl_tls_security_options = $smtpd_sasl_security_options
smtpd_sasl_local_domain = HowTo moim skromnym zdaniem wymaga kilku poprawek przy komentarzach:
1) smtpd_recipient_restrictions - ten parametr sprawdza adres odbiorcy, a nie nadawcy (RCPT TO:)
2) smtpd_sender_restrictions - ten natomiast sprawdzać adres nadawcy (MAIL FROM:)
3) smtpd_sasl_security_options - ten parametr ustawia dozwolone sposoby autoryzacji (a nie zabronione)

Jeżeli ktoś z Was ma jeszcze jakieś poropozycje połatania Postfixa, to napiszcie.
