smtpd_recipient_restrictions = check_policy_service inet:[127.0.0.1]:60000, permit_mynetworks, reject_unauth_destinationrestrikce JDOU po sobe ! (rozumej cteni pravidel ...),tzn check_policy_service musi byt posledni ... Takto:
smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination, check_policy_service inet:[127.0.0.1]:60000Protoze ty to mas obracene, tak se provede pravidlo: check_policy_service inet:[127.0.0.1]:60000 a na ostatni se uz nedostane .. Pak postgey uz pozdeji to ma ve whitelistu, tak se to chova OK Vice zde a zde
Tak je to spravne ... Tak to ma byt
U greylistingu se muze stat, ze nektery mail server ZNOVA tu zpravu neposle (takovy mailserver je blbe nakonfigurovany, takova je ale bohuzel skutecnost), ale u normalnich systemu to MUSI byt OK ...
Nicmene doporucuji sqlgrey a je k nemu i webinterface ...
se mi to stale vraci s chybou: 450 4.7.1To "stale" asi ted znamenalo, ze se maily nedoruci uz ani po tech 5ti minutach, po kterych se ti to pred upravou main.cf preci dorucovalo ne?
Poslu si testovaci email a vrati se mi zpatky.Pokud se testovaci mail vrati s kodem 4xx, tak je to spravne.
Zkusim to jeste jednou a doruci se mi.To je normalni stav. Dulezite je, jestli se prvni mail vratil s kodem 4xx, pak uz to zalezi jenom na nastaveni mailserveru, ktery ho odesilal, zda ho bude posilat jeste jednou a pokud ano, tak za jak dlouho. V Postfixu je nastavena v defaultu hodnota 20 minut.
mydestination = $myhostname, localhost, $mydomain
relay_recipient_maps = hash:/etc/postfix/your_recipientsno a postfix pak vi o "lokalnich uzivatelich ... " a nezapomen: Note: the Exchange domains in question MUST be entered in relay_domains, and NOT in mydestination.

#!/usr/bin/perl -T -w # Version 1.02 # This script will pull all users' SMTP addresses from your Active Directory # (including primary and secondary email addresses) and list them in the # format "user@example.com OK" which Postfix uses with relay_recipient_maps. # Be sure to double-check the path to perl above. # This requires Net::LDAP to be installed.

error:49 error name: LDAP_INVALID_CREDENTIALS error text: The wrong password was supplied or the SASL credentials could not be processedChjo, co mam kde jeste spatne ?
Please note that if the password you use contains the $ sign (and perhaps others? I am not familiar with perl really, but some characters such as $ and probably also quotes have special meaning) you will have to escape them appropriatly with the backslash or perl will complain. For exaple, if your password is: pa$$word, you would have to enter: pa\$\$word hereCely problem bylv tom, ze heslo obsahuje znak "$". Doplnil jsem pred onen znak "\" vse funguje
.
Vsem dekuji za spolupraci, za napady, za trpelivost
Tedy pokud jeste upravis toto:
unknown_local_recipient_reject_code = 554
ale proc se mu to vrati s chybou 5xx, kdyz mu to muj server zamitne s chybou 4xx, ze to ma zkusit pozdeji.
Chjo, jsem z toho uz jelen
