Do you host your mail server at home or in an office, or is it in a data center? If you host it yourself: Please ask your ISP if they block port 25.
hello , my server is at home , my ISp block port 25 , i use smtp redirect to another port and work fine ( for receive), for outgoing i have set in main.cd relayhost = smtp.wanadoo.nl (my isp) but doesn't work ..... if i telnet smtp.wanadoo.nl 25 , i don't have answer ..... can i use another port ? thanks
You can use only the ports that the smtp.wanadoo.nl offers. I've just tried to telnet that server from my own server (in a data center), and also can't connect. Are you sure this is the correct server? If so, I'd contact the Wanadoo support and ask what's wrong.
