Zdravím, při nové instalaci postfix + dovecot na ubuntu 14.04 LTS jsem si nastavil, co jsem potřeboval: postfix master:

Email v pořádku došel do schránky. Následně jsem se pokusil přidat účet do Thunderbirdu. Účet se úspěšně připojil a načetl přijatý email. Následně jsem se pokusil email odeslat, ale vypíše mi to pouze toto:

Poslání zprávy selhalo.
Zprávu se nepodařilo odeslat, protože spojení se SMTP serverem mx2.mojedomena.cz vypršelo. Zkuste to znovu, nebo kontaktujte správce sítě.

V logu na serveru není nic - mail.log

Email, který odešlu přes telnet i na jinou schránku v jiné doméně např na gmail účet, na tento doručený email můžu odpovědět a email dorazí do schránky na mx2 server. Můžete mi prosím poradit, kde mám něco špatně, nebo zda bych měl něco jinak nastavit? Děkuji předem za tipy a rady
