A napr. pres netcat nebo telnet se na venkovni port 25 pripojit jde ? Tohle vypada jako kdyby byl zablokovan pristup na venkovni port 25

[Chulda]

Souhlas. Někteří ISP port 25 ven blokují. Buď si to nechat odblokovat nebo nastavit relayhost na jejich mailserver (možná i o tohle bude třeba zažádat).

[mchf]

Hodilo by se nastavit do relayhost nejaky smtp server.

[HrabalVojta]

Poskytovatel se po týdnu přiznal, že opravdu byla chyba na jejich straně i když velmi dlouho zapíral. Asi po experimentu s jejich smtp šli hledat chybu.

Telnet 25 na jejich smtp funguje. Ven ne.
