    I have successfully installed ISPConfig on my debian system.. So postfix is running, and i can telnet to my server through 25 and 110 ports succesfully. But, when i set up the mail account in outlook, it allways returns error, like username or password is wrong. I have added that user through ISPconfig -> Site -> User &E-mail -> NEW.

    But apparently, this user still doesnt exist, or ain't allowed to acces my mail server.

    Im guessing, if there might be a problem with DNS's? :confused:
    If i type "dig MX" i get an mx record to

    Should I do something with this domain ( in ISPConfig ?
    I'm kind of confused here, please help.
    Tnx to everyone :D

    Not to test it, but yes if you want to receive email from internet. Go to co-domains inside your domain to add

    If you send an email from OE to your server to your email is it delivered?

    Do you use the correct user name (something like web1_user) and password?
    Any errors in your mail log?
    Which distribution do you use?

    I get this error, if I try to send e-mail to the account that I created:
    Technical details of permanent failure:
    PERM_FAILURE: SMTP Error (state 9): 550 <>: Recipient address rejected: User unknown in local recipient table

    this debian I use:
    Kernel Version 2.4.27-2-386
    Distro Name Debian 3.1

    Where can I see postfix error log?

    Tnx guys ;)

    Now, suddenly, outlook stopped rejecting username and password (i think it's somehow connected with the dns server refreshing time).

    But now i get this error when i try to send an email via outlook:

    The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was ''. Subject 'test', Account: '', Server: '', Protocol: SMTP, Server Response: '554 <>: Relay access denied', Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79 is some working mail adress.

    and also, if I try to send a mail from somewhere else to my, i get this err:

    Technical details of permanent failure:
    PERM_FAILURE: SMTP Error (state 9): 550 <>: Recipient address rejected: User unknown in local recipient table

    any ideas?

    Ok, changes again :)

    I removed reject_unauth_destination from my in Postfix

    now things changed a bit..

    If i send a mail to, i don't get an error anymore, and it looks like the mail has been sent successfully. But never cames...

    If i send a mail from account in Outlook, it just waits and waits, and then returnes the usual outlook err msg: SMTP server did not respond in 60s...blabla..

    It looks im getting closer, but I'm still not there yet...

    I found an mail.log, and has lots of entries like this:
    Any help'll do!

    Please run
    postconf -e 'smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination'
    and restart Postfix.

    this string 'reject_unauth_destination', was there before, but i removed it manualy... now with that code u suggested, that came back ofcourse. But this makes things even worse. Now i'm exactly there where i was 5 posts above..
    Now if i try to send an e-mail to my account, I get an error right back:

    Technical details of permanent failure:
    PERM_FAILURE: SMTP Error (state 9): 550 <>: Recipient address rejected: User unknown in local recipient table

    if I remove 'reject_unauth_destination', then e-mail is sen't succesfully, but it never cames, though I can see it, in my Maildir folder...

    I hope, you understand, what I'm trying to say, couse my english is a little poor :)

    Tnx again, falko

    You men you see the email in the maildir folder but cant fetch it with pop3 / IMAP?

    Then you must either switch from maildir to mbox in ISPConfig or install an maildir capacle pop3 and imap client like courier or dovecot on your server.

    Can you post your real domain name here?
    Don't remove reject_unauth_destination.

    Do not correct anything in the virtusertable file manually! It's useless as ISPConfig removes your changes.

    Does the website has a co-domain with empty host field? If not, create that co-domain.

    heh, great, finally some progres!

    I found out, that the e-mail is sent successfully, if I send it to, and not to the ""
    why is that so?

    not a big problem, just wondering...

    E-mail, cames in Outlook to!
    But if I make reply, it says:

    any ideas on that one?

    The relay problem is because the "SMTP server requires autentication" checkbox in outlook.

    The account problem is because postfix isnt reading your aliases config file, did you change something on postfix.conf?
