No a na co se chceš přihlásit na SMTP nebo IMAP?

Co to vypíše za chybu?

Jinak zvenku tak to může blokovat firewall, nebo nastavení těch programů a pokud se chceš přihlásit z internetu potřebuješ veřejnou IP nebo aspoň přesměrovaný port.

[Petr Šobáň]

Jinak jednoduchý test:

telnet server protokol a pokecat si:

[petr@soban ~]$ telnet soban smtp
Trying 127.0.0.1...
Connected to soban.
Escape character is '^]'.
220 soban.doma ESMTP Postfix
HELO soban

quit

[petr@soban ~]$ telnet soban pop3

Escape character is '^]'.
+OK Dovecot ready.

z localu:

telnet localhost imap
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
* OK Dovecot ready.
 

zvenku:

 

telnet MOJEip smtp
Trying MOJEip...
Connected to MOJEip.
Escape character is '^]'.
220 mail.mojedomena.cz ESMTP Postfix (Debian/GNU)
 

u pop3 mmi ti pise telnet: Unable to connect to remote host: Connection refused
 

podle meho by to melo byt ok?

jinak zkousim thunderbirda - to nastaveni mi extra nejde - zadam tam mailovy ucet, imap, v nastaveni zabezpeceni mam "NIKDY" (zkousel jsem i to ostatni take bez uspechu) a "nepouzit zabezpecenou autentizaci" adresa serveru jsem zadaval mail.mojedomena.cz (i mojedomena.cz)

chce to po me (pri prijmu zprav) zadat heslo tak hned jak ho zadam tak: prihlaseni k serveru mail.mojedomena.cz selhalo  (nebo jen mojedomena.cz)

[Petr Šobáň]

Není to v pořádku.

Dovecot poskytuje jak POP3 tak IMAP.

Takže běží dovecot ? Co je v logu od dovecotu při pokusu o spojení ?

 

[Nes]

v dovecot-info jsem pri tomto odmitnuti nasel (thunderbird napsal ze prihlaseni k serveru mail.mojedomena.cz selhalo):

 

dovecot: .2008-12-31 14:22:30 .Info: imap-login: Login: user=<nes@mojedomena.cz>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured
dovecot: .2008-12-31 14:22:30 .Info: IMAP(nes@mojedomena.cz): Disconnected: Logged out
 

 

[Nes]

edit - omyl - nenapise nic - to napsal pri prihlaseni pres roundcube (ma nastaveno automatickou kontrolu zprav) - pres toho thunderbirda ani tuk.

[Nes]

odesilani pres smtp mi funguje ale nefunguje prijimani pres imap

 

FW mam vyply, verejnou IP mam

[Dušan Hokův]

a co vam teda napise po prikazu:

telnet vaseverejnaip imap ?????

[Nes]

telnet mojeverejnaip imap
Trying mojeverejnaip...
Connected to mojeverejnaip.
Escape character is '^]'.
* OK Dovecot ready.
 

[Dušan Hokův]

tak v tom pripade vam imap server bezi, a pripojite se na nej i zvenku

[Nes]

on bezi, ale pripojit se proste neda

jeste prikladam dovecot.conf

ps: tady neexistuje moznost to hodit do CODE?

[faha]

Bude treba trochu debugu pro zjisteni kde je problem, podle vse jak pisete tam tam IMAP server nasloucha, pokud dostanete vyzvu

potom co zkusite telnet VASE_VEREJNA_IP 143

(mimochodem, zkousel jste to z LAN ve ktere je server nebo jen z localhostu a pak z venku? Je vas server primo na verejne IP nebo delate portforward?)

 

Doporucuji pred debugem schodit firewall, zalezni na vasi distribuci ( #/etc/init.d/iptables stop), ale lze to resit i jako

#iptables -P INPUT ACCEPT

#iptables -P OUTPUT ACCEPT

#iptables -P FORWARD ACCEPT

(pro jistotu defaultni po;litika na acceptm pro vsechny retezce)

----

Dle info z vaseho konfig dovecotu mate log /var/log/dovecot.log

zpustte na server prikaz , mel by zacit zobrazovat obsah logu

#tail -f /var/log/dovecot.log

A nyni se zkuste pripojit zvenku na IMAP , pozorujte co rika log soubor jeho vystup zkuste zaslat sem, mohlo by to pomoci v diagnostice.

Pokud tady nic nevypadne, sel bych cestou tcpdump a podivat se zda-li opravdu nejaky pakety prisli, pripadne bych se ujistil, ze na druhe strane z aplikace thunderbird/stroje opravdu data odchazeji pokud je to Windows tak pres ethereal/dnes Wireshark pokud Linux tak pres tcpdump.

bash: /etc/init.d/iptables: není souborem ani adresářem

 telnet 193.19.177.53 143 (z jineho pc)
Trying 193.19.177.53...
Connected to 193.19.177.53.
Escape character is '^]'.
* OK Dovecot ready.

 

kdyz to zkousim z domu pres TB tak dovecot.log beze zmeny, dovecot-deliver.log take bez zmeny, ale dovecot-info.log mi napsal: 

dovecot: .2009-01-04 10:51:07 .Info: imap-login: Disconnected: user=<nes>, method=PLAIN, rip=83.240.13.204, lip=193.19.177.53

ta IP 83.... je IP doma ze ktere se pripojuji

IP 193.... je IP na ktere bezi log a tudiz i dovecot

u vsech techto pokusu mi TB napise pripojeni k serveru mail.mojedomena.cz selhalo

to tedy znamena ze se spravne pripoji, ale z nejakeho duvodu se nemuze zalogovat a stahnout zpravy?

jeste me napadla jedna vec - TB mi vzdy napise zadejte heslo pro USER@mail.mojedomena.cz - neni chyba v tomto? nemelo by to byt jen USER@mojedomana.cz ?

Neni treba nekde povolit mou IP ze ktere se pripojuji?
