Dotaz: postfix nedoruceni mailu - mail delivered system

[alim]

Dobry den, mam mailovy server postfix + virtualni hosty vse narame fungovalo posledni rok bez problemu, ale nyni POSTUPNE navysovali maily, kdy pri odeslani e-mailu do sveta se vratili zpet s chybou o nedoruceni:

priklad: Final-Recipient: rfc822; alim@unet.cz Original-Recipient: rfc822;alim@unet.cz Action: failed Status: 5.4.4 Diagnostic-Code: X-Postfix; Host or domain name not found. Name service error for name=unet.cz type=A: Host found but no data record of requested type

co se mohlo stat? v posledni dobe jsme aktualizoval system, tedy se zaktualizoval postfix+ ostatni potrebne k mailovani, v prosinci jsem menil dns servery! myslim si ze to MA neco spolecneho s tim ale kdyz dam nslookup unet.cz

nslookup unet.cz Server: 93.99.200.1 Address: 93.99.200.1#53

Non-authoritative answer: Name: unet.cz Address: 84.16.96.12

nebo dig tak je vse ok a nove dns servery mi odpovijaji..

dekuji za jakykoliv napad.

Non-authoritative answer: Name: unet.cz Address: 84.16.96.12

Tohle je špatně, zkontoorlujte si SOA záznam v unet.cz a i v reverzní zóně.

domena unet.cz neni moje.... tam odesilam mail.... tedy je chyba v DNS?

[Ripper]

A na jinou doménu odesílání funguje?

[alim]

jdou posilam maily pouze ktere jsou uvedene na serveru odeslat nejde na seznam.cz ani centrum.cz >>> nikam! Divne mi prijde ze jsem neupravoval zadny config a najednou prestalo fungovat. nebude to neco s DNS?

[Ripper]

Tak sem postněte konfiguráky postfixu.

[Ripper]

Ano chyba je v DNS záznamu u domény unet.cz

nejde poslat mail nikam! config:
myhostname = mail.abc.cz
alias_maps = hash:/etc/aliases

myorigin = /etc/mailname
mydestination = mail.abc.cz, localhost, localhost.localdomain,
relay_domains = $mydestination

receive_override_options = no_address_mappings

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# TLS parameters
smtpd_tls_cert_file = /etc/postfix/smtpd.cert

[Ripper]

Chybí vám tam:

mydomain = abc.cz

relay_domains = $mydestination je špatně nahraďte takhle:

relay_domains = proxy:mysql:/etc/postfix/mysql-virtual_domains.cf

[alim]

funguje to dekuji!
