    I have installed a fresh debian6 with ispconfig 3.0.5.2.

    I have enterd a Mail-Domain, and on my Mailprogramm, I have create the account for imap and smtp

    I see the "Welcome"-Mail of ispconig, but can' recieve or send Mails.
    If I try to send a Mail, i got the message "Connection Refused".

    netstat -tap show this:

    I have used the Documentation for "Perfect-Server": http://www.howtoforge.com/perfect-server-debian-squeeze-with-bind-and-dovecot-ispconfig-3-p4

    I also try to deactivate the firewall in ispconfig gui, but same result. "Connection refused"

    Are you expecting your mail to be sent/arrive on TCP port 25?

    I'd double-check your output you posted as there doesn't seem to be anything listening on that port according to what you listed?

    Ok, sorry for waiting. I have reinstalled the whole Server with Debian7 now.


    Same Problem.
    After i create a new Mail-Domain, i got a Welcome-Mail on my account. But if i try to send a Mail, i got "Connection refused". I also got no Mails, which are send to this email-adress.

    In /var/log/mail.err I see :
    Code:
    amavis[1241]: (01241-11) (!!)TROUBLE in process_request: connect_to_sql: unable to connect to any dataset at (eval 111) line 247, <GEN35> line 420. at (eval 112) line 322, <GEN35> line 420.
    
    and in mail.warn I got an error, for missing mysql:
    Code:
    postfix/proxymap[22115]: warning: connect to mysql server 127.0.0.1: Can't connect to MySQL server on '127.0.0.1' (111)
    
    So i had a look into /etc/postfix/mysql-virtual_mailboxes.cf

    I use those connection-Data and log me in. But i didn't see any other DB as "information_schema, dbispconfig, test".

    Must there be a db for my mails?!

    Code:
    netstat -tap | grep mysql
    tcp        0      0 *:mysql                 *:*                     LISTEN      24118/mysqld    
    tcp        0      0 localhost.localdo:36780 localhost.localdo:mysql ESTABLISHED 2161/amavisd-new (c
    tcp        0      0 localhost.localdo:mysql localhost.localdo:36790 ESTABLISHED 24118/mysqld    
    tcp        0      0 localhost.localdo:36790 localhost.localdo:mysql ESTABLISHED 22121/amavisd-new (
    tcp        0      0 localhost.localdo:mysql localhost.localdo:36780 ESTABLISHED 24118/mysqld

    I found a solution:

    On /etc/postfix/main.cf there was this Config by default:


    inet_interfaces = loopback-only

    I have switch it to
    inet_interfaces = all

    and Mails will be send.
