    Hi!

    I have a problem when sending a mail to [email protected] (siol.net is my ISP) and others as yahoo (but gmail works fine)
    I have followed instructions in this howto:
    http://workaround.org/articles/ispmail-etch/

    My /var/log/mail.log file with error of this:
    Code:
    Oct 17 20:08:47 streznik postfix/smtpd[11046]: connect from localhost.localdomain[127.0.0.1]
    Oct 17 20:08:48 streznik postfix/smtpd[11046]: 1E2301F337A: client=localhost.localdomain[127.0.0.1]
    Oct 17 20:08:48 streznik postfix/cleanup[11049]: 1E2301F337A: message-id=<[email protected]>
    Oct 17 20:08:48 streznik postfix/smtpd[11046]: disconnect from localhost.localdomain[127.0.0.1]

    Oct 17 20:08:48 streznik postfix/smtp[11051]: 1E2301F337A: host mailhub.siol.net[193.189.160.212] refused to talk to me: 421 Service not available
    Oct 17 20:08:48 streznik postfix/smtp[11051]: 1E2301F337A: host mailhub.siol.net[193.189.160.25] refused to talk to me: 421 Service not available
    Oct 17 20:08:48 streznik postfix/smtp[11051]: 1E2301F337A: to=<[email protected]>, relay=mailhub.siol.net[193.189.160.211]:25, delay=0.72, delays=0.42/0.03/0.28/0, dsn=4.0.0, status=deferred (host mailhub.siol.net[193.189.160.211] refused to talk to me: 421 Service not available)
    
    I send a mail to my ISP asking what could be wrong, because my ip resolves to my domain name and vice versa. And I got a reply explaining me that this error is shown because I send mail throu their server mailhub.siol.net and that if I have my own server I should send mesages throu it. Or else this relaying thing has to be configured.

    I read something about this on postfix sites but I kinda don't understand. Could someone explain in some simple way what this means, and give me a hint in which direction I have to search to repair this error?

    Thank you,
    Matic

    Most likely your ISP does not allow relaying through their servers from any email account not originating within that server(s).

    I would like to send email from my server, not relay throu some other servers.
    Any ideas?

    Yes, shit, I am blacklisted. I need to set some security settings. Hmm .. Tnx falko. If I set these settings right, so I don't get blacklisted, then my server should work ok?

    Yes. But if your server is running on a dynamic IP address, it will always be blacklisted because most dynamic IP addresses are automatically blacklisted.

    If you have a static IP address and have fixed your server, you must contact the blacklist maintainers and ask them to remove your server from their blacklists.
