Zdravim. Zacal jsem s migraci dat a sluzeb na novy zelezo s cistym systemem a mam docela problem s postou.
Pouzivam debian squeeze s aktualnima balikama postfixu, dovecotu a mysqld.
Nyni k problemu: Udaje o schrankach a domenach mam v mysql, abych si je moh administrovat pres postfixamina. Odesilani posty ze schranek bezi bez problemu. Pokud mi ale pride posta na nejakou z danejch schranek, spadne mi client (thunderbird). Koukal jsem se, co se s postou deje a vypozoroval sem nasledujici:
priklad:
1277032543.Vfd00I3c1978M530835.mydomain:2,
ale melo by to vypadat takto:
1277032543.Vfd00I3c1978M530835.mydomain:2, S
Pokud si rucne dopisu do nazvu soboru flag nakonec, client nepada a vidim v nem novou zpravu.
Presne ten samej problem jsem resil uz pred rokem, bohuzel sem si nezaznamenal cim to bylo :/
Jinak pouzivam stejny konfiguracni soubory jako na starym serveru a data mam s identickyma pravama rsyncnuty na ten novej server. Uzivatele jsem taky zkopiroval. Je teda dost dobre mozny, ze jsem vynechal nejaky nastaveni mimo /etc/dovecot a /etc/postfix.
Pokud nekdo vidite nekde chybu nebo Vas neco napada, budu vdecny za kazdou reakci, komentar a predevsim pomoc. Diky

Pro priklad uvadim sve nastaveni:

}
protocol pop3 {

pop3_uidl_format = %08Xu%08Xv
pop3_client_workarounds = outlook-no-nuls oe-ns-eoh
mail_plugins = quota
}
V /var/log/mail.log je videt ze mail se normalne prijmul:

zkousel jsem i Vase nastaveni a problem zustava, pouzivam imap, pop3 ne
Pred par minutama jsem vyzkousel i cisty konfiguraky z balicku postfixu a dovecotu z repoziraru s modifikaci podle tohohle navodu a problem zustava. Vsechno funguje v poradku do ty doby, nez se pripojim clientem a dojde k presnunu mailu z /new/ do /cur/. Opet neni nazev souboru ukoncen flagem. :/
# dpkg -l | grep dove ii dovecot-common 1:1.2.11-1 secure mail server that supports mbox and maildir mailboxes ii dovecot-imapd 1:1.2.11-1 secure IMAP server that supports mbox and maildir mailboxes ii dovecot-pop3d 1:1.2.11-1 secure POP3 server that supports mbox and maildir mailboxes
protocol imap dát
login_greeting_capability = yes imap_client_workarounds = tb-extra-mailbox-sep
Restarting IMAP/POP3 mail server: dovecotError: Error in configuration file /etc/dovecot/dovecot.conf line 17: Unknown setting: login_greeting_capability
Fatal: Invalid configuration in /etc/dovecot/dovecot.conf
failed!
Pokud smazu login_greeting_capability a pridam pouze imap_client_workarounds = tb-extra-mailbox-sep problem pretrvava.
Tak sem prave vyzkousel m$ outlook 6ku a ta prekousne ty nazvy souboru bez flagu na konci v pohode.
Netusite nekdo jestli musi bejt dovecot nejak specialne nastaven aby spolupracoval s thunderbirdem korektne?
Thunderbird 2 i 3 mi okamzite crashne po prijeti zpravy (= na konci nazvu souboru chybi flag), outlook 6 v poradku prijme zpravu.
