Zdravím, měl bych ještě jeden problém. Kombinoval jsem návod z AbcLinuxu, inspiraci z kofiguračních souborů původního serveru a inspiraci z netu, abych dal dohromady smtp autorizaci. Došel jsem do stádia, kdy autorizace funguje. Tím myslím, že pokud daný účet na server existuje, tak se autorizuje. Pokud ne, je spojení odmítnuto. Pokud ale v poštovním klientu nastavím, aby žádnou autorizaci neposílal, tak mail server stejně odešle.

Otázka tedy je, jak udělat, aby při anonymním příhlášení spojení taky odmítnul.

Už do toho koukám celkem dlouho, takže možná něco pořád přehlížím.

/etc/sasl2/smtpd.conf

pwcheck_method: authdaemond
log_level: 3
mech_list: plain login
authdaemond_path:/var/run/authdaemon.courier-imap/socket

Výše uvedená autorizace funguje pouze pokud do adresáře /var/run/authdaemon.courier-imap je pro skupinu other právo spouštět. Což asi taky není úplně v pořádku.
