    I am using SuSe 9.3 and installed Postfix following The Perfect Setup - SUSE 9.3 (Postfix With SMTP-AUTH And TLS )

    server1:~ # telnet localhost 25
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.
    220 mail.57.ro ESMTP Postfix
    ehlo localhost
    250-mail.57.ro
    250-PIPELINING
    250-SIZE 10240000
    250-VRFY
    250-ETRN
    250-STARTTLS
    250-AUTH PLAIN LOGIN
    250-AUTH=PLAIN LOGIN
    250 8BITMIME
    quit
    221 Bye
    Connection closed by foreign host.

    It seems to be ok
    Ive installed Courier-IMAP/Courier-POP3

    My problem is that I don't know howto add an account like [email protected],[email protected],[email protected] etc
    Don't know how to add user and password for this accounts
    I've searched on Internet but nothing matching with my request was found.

    If someone can help me thanks in advance

    please detail like for dummies

    Thanks very much I've tried but dont understand

    Step 1 OK done it
    postconf -e 'home_mailbox = Maildir/'
    postconf -e 'mailbox_command ='
    /etc/init.d/postfix restart

    Step 2

    useradd -d /home/sample_user -g users sample_user
    passwd sample_user

    I dont understand i make a user with the home directory /home/sample_user and group sample_user and the password sample user

    Please detail for me like for dummies

    Step 3

    postconf -e 'virtual_maps = hash:/etc/postfix/virtusertable'
    postconf -e 'mydestination = /etc/postfix/local-host-names'

    Ive made a file virtusertable in /etc/postfix
    Made a file local-host-names in /etc/postfix

    Step 4
    Inserted in file /etc/postfix/local-host-names domains to accept emails

    Step 5

    Inserted in file /etc/postfix/virtusertable

    [email protected] sample_user
    [email protected] sample_user
    [email protected] sample_user

    You must replace the username, password and home directory appropriately.

    Again, replace sample_user appropriately.

    And don't forget to run
    Code:
    postmap /etc/postfix/virtusertable
    /etc/init.d/postfix restart
    at the end.

    solved half of my problems

    Now I can receive emails but cannot send

    He said he cannot connect to SSL Server.Looking in log mail i found TLS no entropy and I uncomment in master.cf the line
    tlsmgr unix n1000? 1tlsmgr

    When I try to send emails he can connect to server(TLS conection established TLSv1 RC4-MD5 ,SASL LOGIN authentification failed) but he did not reconigze user and password.

    Can you send emails when you connact with plain smtp without TLS?
     
  7. mavgh1

    mavgh1 New Member

    cannot send Mail with no TLS

    I have the same problem SASL conection failed.
    I must tell you that I'm running the server behind a router.Everything is configured to work behind the router(DNS,FTP etc and it works).When I receive mail I think there is the same problem he must route packets from Public IP to Private IP.
    Thanks anyway for your time and still hope for some help.

    What's the exact error message?
    Is saslauthd running? Please post the output of
    Code:
    ps aux|grep sasl

    this is ps aux|grep sasl

    root 6064 0.0 0.2 4060 1176 ? Ss Mar06 0:00 /usr/sbin/sasla uthd -a pam
    root 6103 0.0 0.2 4060 1176 ? S Mar06 0:00 /usr/sbin/sasla uthd -a pam

    root 15294 0.0 0.1 1796 636 pts/1 R+ 00:38 0:00 grep sasl



    When I maked the user and password I used the following syntax

    The account is [email protected]

    useradd -d /home/user1 -g users user1
    passwd user1

    In /home I made a folder user1
    I think its that's correct because I can login to IMAP.
    Thank you again for your quick response and patience.

    What's that? Is it possible that kwrite hangs when you try to edit /etc/postfix/sasl_passwd?
    I recommend to use vi on the command line to edit files: http://www.howtoforge.com/faq/12_15_en.html

    Can you post the exact error message from your mail log?

    Are you absolutely sure you use the correct username and password for sending emails?
     
  13. mavgh1

    mavgh1 New Member

    password

    With the same password I authenticate to IMAP.
    If I dont use server authentication for outgoing mail I can send email from my server from [email protected] to [email protected].

    falko Super Moderator Howtoforge Staff

    You don't need to authenticate if you
    - send from localhost (e.g. with Webmail)
    - send to a recipient that's on the server
    - your client is within the mynetworks variable in /etc/postfix/main.cf.

    what you suggest me to do

    What you suggest me to do.Everything seems to be ok but I cannot login.
    Shell I use sasldb,change the authentication mode ?

    falko Super Moderator Howtoforge Staff

    Please compare your configuration with the one from the SuSE 9.3 tutorial. It's working, I tested more than once, so I guess you maybe made a typo somewhere.

    mavgh1 New Member

    solved problem

    In /etc/sysconfig/saslauthd I changed

    SASLAUTHD_AUTHMECH = pam change it to
    SASLAUTHD_AUTHMECH = shadow
    restart saslauthd and postfix and it works

    Still have a question why yahoo.com send my emails to Bulk

    Many thanks to Falko for his time.

    This can have many reasons:
    - You're sending from a dynamic IP address/DSL line/dial-up account,...
    - You don't have proper PTR and SPF records.
    - Your IP address is on a blacklist.
    ...

    I'd contact the Yahoo support and ask why this happens exactly.
